Everything You Need to Know About Car Batteries

How to Know if Your Car Battery Needs to Be Replaced

Knowing how often to replace your car battery can be tough since some of the signs aren’t incredibly visible at first. If your battery needs to be replaced, one or more of the following may be true:

• You require frequent jump-starts
• Your headlights are dimmer than usual
• You notice unusual power fluctuations
• You have trouble turning the engine on or notice a long turn-over time

If you notice any of these signs or others, it could be time for a battery replacement. If you plan on replacing the battery yourself, learn how to remove a car battery properly with Kareem Auto Sales Inc.

What Causes Car Battery Deterioration?

As a general rule of thumb as to how often should you change a car battery is that a battery will last for five years or longer with proper care, but there are a number of factors that can shorten its lifespan:

• Extreme Weather – Hot weather can cause your battery fluid to evaporate, and cold weather can drain the last bit of life from a nearly-dead battery.
• Lights Left On – Any issue that requires you to jump-start your car will also reduce the lifespan of your battery.
• Vibrations – If your battery clamps become loose, the additional vibrations will cause your internal battery parts to break down more quickly.

Under normal circumstances, the alternator in your vehicle will recharge your battery while you drive. However, even the best battery can only go through so many charge cycles before it dies for good! Even if you take good care of your battery, you’ll eventually need to know how often should you replace your car battery.

How to Test a Car Battery

It’s smart to test your battery at least twice a year. How long do car batteries last? You can ask your local service center to test your battery during any regular service appointment. If you’re worried about the health of your battery and want to test it out before heading on the Roseville roads, you can also test it yourself at home using either of the following methods:

Using a Digital Multimeter:

1. Set your voltmeter to 20 DC volts.
2. Lift the hood and connect the negative (black) terminal to the negative (black) meter probe. Do the same for the positive (red) terminal and meter probe.
3. Turn the key so that the headlights come on, but don’t start the car. Check the reading on the voltmeter.
4. Measurements can vary slightly by temperature, but in general, a measurement of 12.5 volts or higher is indicative of a full charge. At 12.3 volts, you’re at roughly 75% battery. With 11.8 volts or lower, your charge is no higher than 25%.

Using the Headlight Test:

1. Start your engine and turn on the headlights. Make sure the car is in park.
2. Rev the engine and check to see if the brightness of your headlights changes.
3. If revving the engine makes your lights brighter, your battery is close to dying.
4. At this point, you should take your car to a service center for a quick checkup and battery replacement.

Knowing the condition of your battery will help you determine how often you should replace your car battery. This simple test should help you determine the current condition of your car battery.

What Does Battery Corrosion Look Like?

Are you experiencing low power inside your vehicle, trouble starting your car, or maybe even you see low voltage codes displayed on your car dashboard during those drives to Elk Grove? Although your battery may be due for replacement, and the problem could have something to do with your alternator, you should check your battery for corrosion before you jump to any conclusions. Here’s how it’s done:

1. Allow your vehicle’s engine to cool for at least 30 minutes.
2. Then, open the hood so you can look at your battery terminals.
3. If the battery terminals are covered in white powdery looking material, tinged with greenish blue or teal, you have battery corrosion.
4. Since this corrosion prevents the terminals from attaching firmly to the battery, it needs to be removed at the earliest opportunity.

How to Remove Corrosion From a Car Battery

By now, you probably want to know how to remove corrosion from a car battery. There are two main techniques to remove car battery corrosion. The first approach is to buy a cleaning solution from an auto parts store around Roseville that is made specifically for auto batteries. 

You could also create a DIY solution yourself using everyday household products. 

Regardless of which procedure you choose, make sure you use gloves, eye goggles, and a respirator or mask when handling the solution or making it. Before you get under the hood, make sure to remove all metal objects, including watches or jewelry, from your person. Safety is always paramount. Here’s how to clean car battery corrosion once you’re ready to get started:

• Professional battery cleaner: Spray the solution generously on the affected area of the battery. Then, brush it vigorously with a wire brush until all of the car battery corrosion is removed.
• DIY battery cleaner: If you’d prefer a DIY solution to how to clean car battery corrosion then follow these instructions. First, remove the connectors from the battery terminal. Then, pour baking soda on the corrosion areas to neutralize the acids. Next, add a little water to create a chemical reaction. Dry it with a paper towel, then brush the affected surface with a scrub sponge or brush.

Now that you know how to remove corrosion from a car battery’s terminals, you can prevent future decay by using an anti-corrosion gel, rust inhibitor spray, a spray battery protector from many auto parts stores.

What Causes Car Battery Corrosion?

What causes car battery corrosion? Don’t blame yourself; the age of the battery and the time that it’s spent in use are the primary causes. Your vehicle’s battery is continuously heating and cooling while the engine runs, and this process requires the release of hydrogen gases through ventilation. These gases are dispersed continuously, and as they mix with surrounding material, they make and deposit a substance at the connection point (AKA the battery terminals) which can cause car battery corrosion.

Do you have a diesel truck battery? Wondering how to charge a diesel truck with two batteries? Diesel trucks offer huge amounts of torque, solid construction, and great reliability. But when you find yourself with a low or dead battery, what do you do? Luckily, it’s not uncommon for diesel trucks to have two batteries, and we can help you learn how to jumpstart a diesel truck with two batteries whether alone or with a friend:

If you have a diesel engine with two batteries, you’ll be able to jumpstart your diesel engine by connecting it to just one of your two parallel batteries. The most accessible option is the battery in your vehicle’s engine compartment. Start your engine, and your alternator will take care of the rest– giving you a charge back into both of your batteries while even idle.

Here’s how to jumpstart a diesel truck with two batteries if you have another vehicle:

1. Make sure both vehicles are in park (automatic transmission) or neutral (manual transmission).
2. Turn off all lights and any other accessories in the vehicle that you’re jump-starting.
3. Next, connect one clamp of the red jumper cables to the dead battery’s positive terminal. The terminal will have a “+” symbol or a red cover over it.
4. Connect the cable’s second clamp to the good battery’s positive terminal.
5. Connect one of the black cable’s clamps to the good battery’s negative terminal.
6. Locate a piece of unpainted metal on the vehicle you’re jump-starting and connect the last black cable’s clamp to it (we recommend choosing the alternator bracket for this).
7. Start the engine on the vehicle with the good battery. Let it run for a few minutes (Your dead battery needs time to recharge).
8. Begin cranking the engine on your diesel truck. It may take a while to fire up, and you may need to give your dead battery more time to charge if cranking isn’t working.
9. When your engine turns over, remove the black cable from both vehicles one at a time. Make sure that they don’t touch any metal, each other, or the red cable.
10. Remove the red cable from both vehicles one at a time. Be alert and mindful until the clamps are detached from all batteries to best avoid possibilities of shock or fire.
11. Let your truck run for a while so that your alternator can put power back into both batteries. We recommend going for a good drive and advise against shutting off your engine for at least 20 minutes total.

How long do diesel truck batteries last? The average lifespan is around four years for a diesel engine, but this will vary based on how often you drive, your driving environment, and so on.
