Ways To Avoid a Dead Car Battery

Most people wait until their car battery dies before they decide to replace it, a recent report revealed. The survey of 1,000 drivers, sponsored by Batteries Plus Bulbs, showed that 53 percent of the group waited until they were stranded by a dead battery and then had to call for roadside assistance.

Here are the five things that will help you avoid a dead battery:

1. Know Your Car Battery’s Age: Most cars require 12-volt batteries that last from three to five years. Therefore, you should know how old the battery is so you can replace it before it fails. Hopefully, you kept the receipt or noted the date when you bought your current battery. Or, perhaps you bought your car new so the battery was also new at that time. But if you are like many people, they bought a car without knowing the age of the battery. Well, it’s time to find how old it is now. Open your car’s hood and locate your battery, which is usually in the right front of the engine compartment. In some cases, the manufacturer places an easy-to-remove plastic cover over the battery. However, other batteries should have a plastic strip with a code on it. Here is a chart to decipher battery codes. If the battery has no date code, you are forced to judge the battery by its general appearance. If it appears old and has white corrosion around the terminals, you will definitely want to get it tested.

2. Look for the Warning Signs of a Dying Battery: You might notice that when you turn the ignition key, the engine cranks slowly. This could be a sign that your battery is about to die, Mazor says. Another telltale sign is to turn on the headlights when the engine isn’t running, he says. If the headlights look dim, the battery could be on its last legs. In some cases, a battery will die without any warning at all. If your car won’t even turn over (there might be a clicking or buzzing sound coming from the electrical system), check first to see if the battery was drained because you left the lights on, or some other electrical device. Once the car is jump started, it could start, run and seem reliable. But the battery will probably fail again shortly, so replace it as soon as possible.

3. Get a Free Battery Test: Most chain auto parts stores will test the battery for free, Mazor says. Furthermore, various mobile services, such as AAA’s Battery Service, will test the battery and let you know if it needs to be replaced. Installation of a new battery and disposal of the old one is usually free. Replacing the battery yourself is possible but not recommended for novices. The connections are often corroded and difficult to loosen. Then, lifting the heavy battery out and installing the new one requires a feat of strength.

4. Replace Your Battery Before It Leaves You Stranded: If your battery fails the free test, or it is cranking slowly, replace it. Use a mobile battery service or go to an auto parts store. The parts clerks will use a battery fitment guide to tell you what your car needs. Batteries are often sold with three-year, four-year or five-year warranties. Since the battery is a vital part of your car, Mazor recommends buying a top performer.

5. Maintain Your Battery: 

Do a visual inspection to check for corrosion around the battery terminals. Look for a chalky white substance that might affect proper electrical conduction. Clean the terminal with a wire brush and coat it with grease before reconnecting the battery. The grease prevents corrosion and improves the electrical connection. If you have an older battery that allows access to the cells, adding distilled water will help it keep a charge. However, if you do this, proceed with caution. The sulfuric acid in batteries is highly corrosive and can burn your skin and eat holes in your clothes. There is even a slight danger of explosion. When performing maintenance on a battery, work in a well-ventilated area and wear gloves and eye protection. If battery acid gets on your clothes or skin, quickly neutralize it with a solution of baking soda and water. Never lean over a battery when charging, testing or jump-starting an engine.

Final Thoughts
The performance of modern batteries has improved, and Mazor says they will perform better for a longer period of time. But they still have one flaw: It’s hard to predict when they will die. So regularly inspect your battery and replace it before it lets you down.
