Automotive batteries help start your vehicle and power all of the core electrical systems. Your car won’t run without one, which is why it’s essential to understand how this part works. The following is a helpful introduction and answers to common questions.

Your Guide to Car Batteries

How do they work?

Automotive batteries use chemical reactions to generate bursts of electricity. These activate the starting motor when you turn the ignition key. The reaction then powers the combustion engine that propels the vehicle. The battery maintains a steady electrical current to run the AC, radio, lights, and car’s computer.

Should I clean mine?

Cleaning helps your battery perform better for longer. Start by disconnecting the positive and negative cables attached to the battery while the vehicle is off. Next, dip a toothbrush in a solution of one cup of water and a tablespoon of baking soda. Carefully scrub the grime from around the terminals. Preventing buildup and corrosion ensures the best electrical connection and current.

Next, rinse the battery and dry it with a towel. Apply petroleum jelly to lubricate the terminals and prevent erosion.

Maintaining your battery also means using it. Try to drive your vehicle several times a week to recharge the battery.

When should I replace it?

The average battery lasts 3-5 years. Your car will struggle to start as the battery fails. Eventually, it won’t crank or start at all. You may notice that the AC doesn’t blow as hard, and you have to regularly jump-start your car.

Batteries may also break and leak. You may notice a rotten egg smell or see acid leaking from it. Hot, leaking batteries are dangerous to handle, which is why it’s best to contact professionals. They’ll safely remove it and then help you find the right replacement for your car.

What happens if I drain the battery?

Many drivers will deal with a dead battery at some point, often from leaving the lights on. You can use another vehicle to jump-start the car. Connect positive (+) and negative (-) jumper cables to the battery's respective terminals. Next, connect the clips to the other car’s battery, making sure you don’t touch them together.

Have the other driver start and run their car for five minutes. Try starting yours. If it starts, run the engine for 15 minutes so the battery recharges. If it doesn’t start, contact roadside assistance. You may need a new battery.
