The car battery is one of your vehicle's most important components. Without one, your car won't start and you can’t use the electrical system. Here’s what you should know about this critical auto part.

A Guide to Car Batteries

How can you tell if you need a new battery?

If the engine is slow to start when you turn the key, it could mean your battery is dying. Dim overhead and dashboard lights when the door is open and the engine is off also signal potential issues. When the battery terminals are corroded, the battery case is misshapen, or the cell is giving off a rotten egg odor, you may need to replace it.

What does the car battery do?

The battery gives off a powerful burst of electricity needed to turn the engine over and get it running. The alternator then replenishes the battery so that it will have enough energy stored to start the engine the next time.

How often should you replace a car battery?

In general, you should replace the battery every three years or so. This makes sure your vehicle starts properly and doesn’t require a jump-start. The precise life span of a battery depends on the climate, your driving habits, and other factors. For instance, batteries wear out more quickly in cold climates and when they are regularly discharged below 50% capacity.

What are the different types of batteries?

The two main types of automobile batteries are AGM and lead-acid. Lead-acid batteries are older but reliable. They’re also less expensive but heavy. AGM batteries tend to be more expensive but are lighter and have a longer life span. They do not contain liquid, and can withstand deeper and more frequent discharging.
