Debunking the Myth of the 12-Hour Lithium Battery "Activation"

When it comes to lithium batteries, there's a longstanding myth that they need an initial "activation" process involving charging for over 12 hours, repeated three times. However, this claim is based on outdated practices, particularly those associated with nickel batteries like nickel-cadmium and nickel-hydrogen, which were popular over two decades ago. It's high time we set the record straight and understand the correct methods and precautions for the first three charges of lithium batteries.

The Dangers of Ultra-Long Charging and Full Discharge

Charging lithium-ion batteries excessively, particularly for extended durations, is unnecessary and can lead to severe damage. Ultra-long charging and complete discharge can result in overcharging and over-discharging, causing irreversible harm to the positive and negative electrodes of lithium-ion batteries.

At a molecular level, excessive discharge forces the release of an excessive number of lithium ions from the negative carbon, leading to the collapse of its layer structure. Conversely, overcharging crams too many lithium ions into the anode carbon structure, causing some to become permanently trapped. This is precisely why lithium-ion batteries are typically equipped with charge and discharge control circuits.

Correct Methods and Precautions for the First Three Charges

Contrary to the outdated belief of a 12-hour charging regimen, lithium batteries today come with built-in charging circuitry that safeguards against overcharging. There's no need to leave your battery plugged in for such extended periods. When a lithium battery is new, after prolonged periods of inactivity, or even after heavy usage, you can simply follow these guidelines:

Fully charge and discharge the battery once.

After this initial cycle, your battery is ready for regular use.

For long-term storage, charge the battery to around 40% or check the voltage of each cell (ideally, 3.83V per cell) before storing it.

If the battery remains unused for an extended period, it's advisable to perform a charge and discharge cycle once a month.

Understanding Charging Methods

Charging lithium batteries is generally straightforward, but safety during the charging process is of paramount importance. Here's a basic outline:

Charge with a stable current, typically ranging from 0.2C to 0.7C, depending on the manufacturer's recommendations.

Continue charging until each unit of the battery reaches 4.2V (volts per cell) and maintain this voltage until the charging current falls to about 10% of the initial value.

The precise peak charging voltage and the end current may vary slightly among different battery manufacturers.

Regardless of these specifics, a charging timer should always include a safety mechanism.When the battery reaches 4.2V per cell, it has only reached 40% to 70% of its full capacity.The charger should not immediately cut off power at this voltage; instead, it should continue charging until the current drops significantly, and then stop charging at a low current.

For those using standard chargers, it's important to note that even if a voltmeter indicates a voltage of 4.2V, the battery is not fully charged. At least 60% of its capacity remains unused. This underscores the importance of using a dedicated lithium charger with constant current and constant voltage charging capabilities.

In summary, forget about the outdated 12-hour charging myth for lithium batteries. Follow the manufacturer's guidelines, prioritize safety during the charging process, and you'll ensure the longevity and efficiency of your lithium-ion batteries.

Understanding Your Heavy Duty Truck Dashboard

There’s a lot going on when you are driving a heavy duty truck. You need to make sure everything in your truck is running smoothly to avoid potential disasters. Heavy duty trucks are complicated and have a lot of moving parts, and for this reason there are many more dashboard symbols and gauges that truck drivers have to keep an eye on.

Here is a guide to help you understand what your truck dashboard symbols, gauges, and warning lights mean.

Common Truck Gauges

Truck gauges provide drivers with vital information about the state of their truck and how it is functioning. All heavy duty truck dashboards have the following truck gauges.

Odometer: All vehicles have odometers, including heavy duty trucks, so most drivers are familiar with this dashboard gauge. The odometer shows the total mileage on your truck, and most odometers can also show the mileage of a specific route you have taken. This information is useful for knowing when your truck needs an oil change and other routine truck maintenance.

Voltmeter: This truck gauge shows the charge of your battering, either with numbers or with three colored sections. If your truck has a numerical voltmeter, it will read 14 to 14.5 volts when your battery is fully charged while your engine is running. This is the range your battery should typically stay in. If your voltmeter consistently reads below 14 volts or over 15 volts, then your batter is under charged or over charged, respectively, and you should have a diesel mechanic check your system. If your heavy duty truck has a colored voltmeter, you want the needle to hover in the middle green area. If it is in the red area to the left, then your battery is under charged, and if it is in the red to the right, then your battery is over charged. Keeping an eye on your voltmeter will alert you to charging issues before they turn into serious problems.

Tachometer: All vehicles have tachometers, too. The tachometer tells you the engine’s speed in revolutions per minute, or RPM. The diesel engines in heavy duty trucks are now designed to have maximum peak torque with lower RPMs.

Fuel Gauge: The fuel gauge is a vital auto and truck gauge in all vehicles. It lets you know how full your fuel tank is. Heavy duty truck drivers should check their fuel gauges regularly so that they can be sure they have enough diesel to make it to their destination. Running out of fuel while on the highway is a less than ideal situation that you want to avoid at all costs.

Engine Oil Pressure Gauge: The engine oil pressure gauge allows you to keep an eye on your heavy duty truck’s oil pressure. You want the oil pressure to stay between 30 and 70 pounds per square inch, or PSI. If your oil pressure is too low, your engine can suffer serious damage.

Air Pressure Gauge: This truck gauge monitors the PSI of each truck reservoir. You should regularly check both your primary and secondary air pressure gauges to make sure they do not fall below 90. If this happens, there could be a leak or some other problem with your air brake system. Pull over as soon as you can before your heavy duty truck experiences a breakdown.

Temperature Gauges: Heavy duty truck dashboards have a number of different temperature gauges. Some temperature gauges should be high while others should be low. Keep an eye on all your temperature gauges to keep your truck performing as it should be. The following are the different types of temperature gauges you will see on your truck dashboard.

Coolant – This gauge monitors the temperature of the coolant and should be around 165 to 195 degrees Fahrenheit. If you notice that your coolant temperature is too high, you need to pull over when it is safe and let it cool down before continuing your drive.

Engine Oil – This gauge shows the temperature of your heavy duty truck’s motor oil. If your oil is too hot, your engine can be damaged.

Pyrometer – This gauge displays the temperature of your diesel engine’s exhaust. This can warn you that your heavy duty truck may have engine damage.

Transmission – The temperature of your truck’s transmission is shown here. You can find out what a normal transmission temperature is in your manual. Normal temperature ranges vary by manufacturer.

Rear and Forward Axles – The temperature of the oil in your axles is shown here. Forward-rear and rear-rear axle oil temperatures should stay around 160 to 220 degrees Fahrenheit for Meritor axles or between 80 and 200 degrees Fahrenheit for Dana Spicer axles. When your heavy duty truck is under heavy loads or climbing steep grades, it is normal for these axle oil temperatures to go up, as long as the temperature falls back to normal afterwards.

Dashboard Symbols and Warning Lights

Heavy duty truck dashboards have a variety of warning lights and dashboard symbols that can indicate both emergency and non-emergency issues. You should familiarize yourself with what the different dashboard symbols and lights mean so that you know if it requires immediate attention. The location, design, and color of each warning light and dashboard symbol can differ among truck manufacturers, but here are explanations of what the most common symbols mean.

Check Engine Light: The check engine light can be indicative of both major and minor engine issues. If your truck’s check engine light comes on, check to see if any other warning lights have come on as well, such as those showing that your diesel engine is overheating or that the oil pressure is low. Pull over when it is safe so that you can turn your engine off as soon as possible.

Alternator Check Light: If your alternator check light comes on, this could be informing you that your truck’s alternator is not correctly charging your battery. When this happens, you should pull your heavy duty truck over when it is safe and only use the necessary battery-operated accessories, such as your windshield wipers, headlights, etc., until you can get the alternator checked by a diesel mechanic.

Low Coolant Level Light: The low coolant level light tells you that your coolant levels are low. This does not need to be attended to immediately, but you should schedule truck maintenance in the near future so that a diesel mechanic can find and fix the cause of this issue.

Tire Inflation Light: This warning light lets you know that one of your tires is underinflated. A tire that is underinflated is likely to cause a serious breakdown or accident. When you see the tire inflation warning light up, find a safe place to park and manually check the pressure of each tire.

Schedule Heavy Duty Truck Maintenance with a Certified Diesel Mechanic

Auto Repair Advice From The Experts In The Field

It's no secret that auto repair costs a lot of money. Complicated repairs and simple repairs alike can both cause you to lose your hard-earned money. That's why you need every advantage possible to reduce the cost of your auto repair bills. In this article, you will find tips that can help you save money on auto repairs.

Buy -  best tire pressure gauge

Do you have a hard time starting your car? Your battery probably needs to be recharged or replaced. You need to check the state of charge of your battery. You can use a hydrometer or a voltmeter, depending on the type of battery you have. If you have been regularly recharging your battery, it might be time for a new one.

If you notice your windshield wipers are not removing all the water from your windshield when it rains, you may need to replace the blades. This is a simple fix anyone can do. Measure the blades and purchase new ones from an auto supply store. Remove the old ones and snap the new ones in place.

When you are in need of an auto repair, shop around to make sure that you get the best deal. Go to at least three different repair shops to get a quote. If anyone charges something that is unrealistically low or high, you should seek someone else to do the job.

Understand the repair costs prior to leaving your car with any shop. Labour costs especially can run at different levels from shop to shop, especially if a specialist is involved. You'll want to know what you are getting into prior to learning about it the hard way days later.

Ask a technician if they are A.S.E. certified before you agree to have them work on your vehicle. If they have this certification, it means they have passed a written test and have worked in the industry for at least two years. You will know that you are getting someone skilled by choosing someone with this.

Do not be afraid to ask a potential technician any questions you have. It is your vehicle that they will be working on, and it is important that someone with the proper qualifications handle it with care. In addition to asking about the problem with the vehicle, ask them any other questions you have about your car.

Your car owner's manual is actually a valuable guide to the workings of your car. That means that you should not trash it as soon as you leave the dealer. It can tell you everything from what that light on your dash means to how to perform basic maintenance on your particular model.

Make sure to ask the mechanic who is about to work on your car whether or not he is certified. If the answer is no, leave right away and get someone else to do the repairs. If he says that he is, ask for some type of proof, so you know this is true.

Although the dealer for your car's make may provide the highest expertise when it comes to repairing service, it may not always be the most cost-effective choice. Many independent car repair shops have technicians that formerly worked at dealerships and are factory trained. You may be able to save a good amount by choosing an independent shop over the dealer without a loss of quality.

When working on your engine, be certain to wear proper safety equipment. You need ear plugs to protect your hearing, goggles to protect your vision and polyurethane or latex gloves to protect your skin from damage and injury caused by acids and other fluids. If you have long hair, be sure to secure it to avoid having it become caught in moving parts.

Keep your auto repair shop business card in your car at all times. You never know when something could go wrong with your vehicle. You'll want your favourite auto shop's phone number handy, though, when it does. Another option is to program all of their contact information in your phone.

Take your owner's manual with you when you go to the auto repair shop to get work done. If someone tells you that you need to get a service after a certain amount of miles, check and see if that matches what is in the manual. If it does not, let them know that you decline that particular service.

Put all the receipts you have for auto repairs in a plastic file, and keep this file inside your car. With that type of file, you can organize your files by time or specific types of repairs. Either way, you will have a complete record of your car's maintenance that will be helpful to your mechanic when more repairs are needed and helpful to you if you are dissatisfied with a repair. It only takes a few minutes to do, and the record can be a valuable tool.

You may need auto repair, but you don't have to break the bank to get it done. There are legitimate ways that you can give your car the repairs it needs while staying within your budget. This article will come in handy, so use it and keep your car running smoothly for less.

The Ultimate Guide To best cleaner for engine parts

Being one of the most crucial components of your car, the engine, it makes sense to know how to clean it. We'll outline what you should do and how in this tutorial.

Overview of engine cleaning

The engine is one of your car's most crucial components because it gives your vehicle power. The machine comprises four main parts: spark plugs, cylinders, valves, and pistons. Additionally, it has coolant pumps and oil filters.

Small Engine Parts Cleaner not only supplies the power but can also produce heat that, if not properly dissipated by airflow through vents or fans in the front or back of the car, could harm other components.

This article will walk you through the step-by-step process of cleaning a standard automobile engine, one with an owner's manual with detailed instructions on where and how to clean them.

Why do you need to clean your engine?

Your engine's health depends on regular cleaning. The engine components can clog up and cause issues if you clean them infrequently.

1: Performance: If the engine is clean, it will run efficiently. It won't generate enough power to operate your car easily.

2: Fuel economy: Because less heat is lost through the exhaust system and more air is flowing through the engine, a clean engine uses less fuel than one that is unclean. Over time, this helps you save money on fuel expenses.

3: Resale value: If a car's owner wants to sell it, they want it to be in excellent condition so that it will sell for a high price at auction or in a private transaction (or both).

By doing routine maintenance in this way, a vehicle's mechanical components — particularly those connected to how frequently they are cleaned out before being reused later on — are kept in good working order, something that may otherwise go unnoticed.

How to prepare the car for cleaning

Get the Best Product For Cleaning Engine Parts to clean your car's engine; experts advise that you take a few steps.

Check the battery and charging system to ensure they are in good working order. 

1: To ensure there is enough power and the terminals are clean, check it with a voltmeter. Additionally, check to see whether your automobile has a good ground for power distribution or if there is water in the battery tray.

2. Inspect the coolant level and top it off as necessary, but avoid overfilling it, as this could lead to spills when cleaning.

 3. Make sure your engine has adequate oil, and if not, add more so that nothing gets caught when you're cleaning out all the pieces on top of them!

4: It's important to check the brake fluid frequently; if there isn't enough, obtain some more before continuing since brake failure could result, which would cause more issues than just filthy brakes. 

You should fix any leaks before adding fresh fluid since if you add new liquid to an existing system, and it won't start working immediately.

Final Words

You ought to be able to clean your engine now that you know how. To sum up:

 Step 1: Use warm water to clean and rinse the engine.

 Step 2: Use a fresh rag or paper towel to dry it.

 Step 3: If your car has no rubber or plastic parts, you can skip this step. Doing so will prevent the elements from cracking or drying out too soon.

 Step 4: Use a grease-cutting cleaner to remove any last bits of dirt. Dish soap can also be used as a last resort!

Things Everyone Should Know About Electricians

As a homeowner, you probably know that you need to hire a professional plumber and an HVAC technician. However, electrical work is also extremely important—and it's something that many homeowners don't consider until they have a problem with their home's wiring or circuit breakers. With this in mind, here are eight things everyone should know about electricians:

Electricians are highly trained.

When you hire an electrician, you're hiring someone with expertise in wiring and electrical systems. Electricians are trained in the use of tools and equipment, such as a multimeter, which is used to measure voltage; a voltmeter, which is used to test for current; and an ammeter, which measures the amount of current flowing through a circuit. Electricians are also trained to install and maintain wiring, lighting and other electrical systems within your home or business.

Electricians must follow federal regulations set by OSHA (Occupational Safety & Health Administration) regarding working safely with electricity. This means that every electrician has completed training on how to avoid shock hazards both while working at heights as well as while standing on the ground level at work sites where electricity may be present even though it's turned off because of faulty wiring or other problems with your home's electrical system

Electricians install and maintain wiring, lighting and other electrical systems.

Electricians install and maintain wiring, lighting and other electrical systems. They also install and maintain electrical appliances, such as electric ranges, refrigerators and washers. They also install and maintain electrical equipment, such as air conditioners, heat pumps and security systems; industrial machinery; high-voltage equipment used in power plants; transformers; switchgear for use in substations or similar locations where large amounts of electricity are used at one time; cable television distribution facilities (including headends); satellite receiving dishes that receive signals from communications satellites; other transmitting equipment which uses radio waves to transmit information between two points (such as mobile phones); any other electronic device that uses electricity to operate itself (e.g., televisions). Some electricians specialize in installing these types of systems while others work on a wide variety of tasks within the field.

Electricians who maintain existing wiring must keep it safe by following all safety regulations set forth by federal laws like OSHA (Occupational Safety & Health Administration) or local building codes established by your state government's department of buildings/codes enforcement agency(ies).

You should always hire a licensed electrician.

One of the first things you should know is that electricians are trained to work with electricity. If a person without training were to do electrical work, they could get hurt or even kill someone. An unlicensed electrician may not be bonded and insured, meaning they aren't protecting you as well as they should be in case something goes wrong during the job. In fact, many states require all licensed contractors to carry both insurance and bonds on their jobsites for this reason!

If an electrician isn't licensed by your state's regulatory board, it's probably because he has yet to complete his training requirements or his application was rejected by the board based on past offenses or poor performance on exams. If you hire an unlicensed contractor anyway (which is very common in smaller towns), then make sure that there's at least one safety inspector present throughout their time working on your property so there aren't any accidents happening later down road somewhere else when no one was around before hand!

You're likely to need an electrician as your home gets older.

Just like any other household item, your home's electrical system will need to be inspected and maintained as it ages. While it's true that the newer homes tend to have fewer problems with their electrical systems, that doesn't mean you can avoid hiring an electrician just because your house is new. As time goes by, you're likely to notice a few issues with the lighting or wiring in your home—and an electrician can help with both of those things.

While there are some basic repairs that homeowners can do on their own (like switching out light bulbs), most people don't have the skills necessary for more complicated repairs. If something goes wrong with your electrical system—and let's face it: things do go wrong!—you'll want someone professional working on it as soon as possible so that there aren't any lingering problems later down the line.

If a fuse blows, you probably have an overloaded circuit.

If you have a fuse blowing every time you turn on your lights, it's probably because the circuit is overloaded. To avoid this problem, make sure that all of the equipment is plugged into a surge protector and not directly into the wall outlet. If that still doesn't work, then you may need to add another breaker to your circuit.

Your circuit breaker may be mislabeled.

Your circuit breaker may be mislabeled. Circuit breakers are labeled with a letter and a number, like A1 or C23. If the label on your breaker is wrong, you could be in danger of overloading that circuit and causing a fire. You should have an electrician check this out if you see something that doesn't seem right.

Smoke detectors protect you from fire damage, carbon monoxide poisoning and more.

Smoke detectors are the best line of defense against fire. They alert you to smoke in your home, which could mean a fire is burning or that something is on fire and needs to be extinguished immediately. Smoke detectors can save lives by notifying you when there’s smoke in your home, allowing you and others time to escape before it spreads into more dangerous flames.

Smoke detectors also prevent carbon monoxide poisoning. This silent killer can cause flu-like symptoms and even death if it's not detected quickly enough. So if you have a CO alarm in your home, make sure it’s working properly! If yours isn't functioning correctly or hasn't been tested recently, install a new one today!

Don't put off electrical repairs.

Don't wait for the problem to get worse. A simple electrical problem can turn into a more serious one if you don't take care of it in time. Get in touch with an electrician as soon as you notice that something isn't working properly and schedule an appointment to have them come out and take a look at your wiring.

Don't wait for a fire or other emergency situation before calling an electrician. It's important to have the proper wiring installed in your home so that you're safe from electrical hazards and fires, but it's also good practice to schedule regular checkups with an expert so that they can identify any potential problems before they become serious issues.

Don't wait until there is a power outage before reaching out to hire someone who specializes in installing new fixtures or fixing existing ones (including those damaged by flooding). You may think this isn't necessary because your current setup works perfectly fine most of the time—but when disaster strikes (and trust me: it will), being prepared could make all the difference between having everything go smoothly versus having things fall apart quickly due.

What Causes Electrical System Malfunction in a BMW?

BMW cars are known for their high performance and sophisticated features. Because of using advanced electrical and electronic equipment, they are having such best features and are proved to be very much helpful. But do you know, such electrical systems can fail with time 

Electrical system malfunctions

As the use of electrical systems has increased in modern models, the chance of electrical system failure increases. Electrical system malfunction is becoming more common in new models. Electrical system issues are mostly nondestructive, major issues can make the car to click or not start at all. Many of the electrical issues can give you headache. So better get it repaired soon so that you can drive your car freely.

Signs of electrical system failure

  Electrical system malfunction message on dashboard

  Difficult to start the car

  Flickering lights

  A burning smell of plastic

  Constant fuse trips

  Battery warning light

  Bad spark plugs

What causes electrical malfunction

Problems in battery

A battery supplies energy to most of the electrical components. It makes the car start. If the battery is faulty, then the car would not start, most of the electrical components like lights, horns would not work properly. A battery stores and supplies the electrical energy. When it goes bad then it would be unable to store much energy and it may drain out the energy. So a faulty battery can be the main culprit for most of the electrical system malfunctions.

If the battery is discharged, then it will not let you start the car especially in colder weather, even the alternator will not able to change your battery due to short trips on traffic.

Damaged wiring

Cables carry out the work of transferring any signals from one unit to the other. Cables are very important in an electrical system. If the cables are damaged, then the circuit becomes open and electricity cannot pass through it.

Blown fuse

A fuse is an electrical safety component which consists of a piece of wire to protect the other electrical components from overloads. The fuse wire has a certain melting point and a certain current rating. If the current magnitude becomes higher than its rated current, then gets heated and melts or breaks. As it breaks, the current cannot pass any more and the other electrical components will remain unharmed. Most commonly, fuses are blamed because a blown fuse becomes the culprit for the electrical system issue most of the times. Therefore it is recommended to first check the fuse box.

A damaged alternator

An alternator is the generator in a car. It utilizes the energy from engine and converts it to electrical energy and then supplies it to battery. If the alternator is damaged, then it will not carry out its work properly to charge the battery and make the car run.

Steering wheel lock error

This error usually comes up when the battery is low during cold weather. In this case, you will not able to start the car after certain number of starts after error comes up. The steering wheel mechanism stops to go back due to low battery and this error is then stored on dashboard.

Problem in i Drive system
