Car batteries, or automotive batteries, are responsible for supplying electrical current to a vehicle. It feeds the starter, which will start the engine.

But what else is there to a car battery? Do you know what affects the lifespan of a car battery? Are there ways to recharge your battery? Do car insurances help you replace your batteries?

Here are some facts about car batteries you may not know:

The weather affects your batteries

We live in a tropical country where it’s sunny all year long. As Malaysia’s climate is warmer than other countries, it affects the car batteries differently too. The heat in our country reduces the lifespan of a car battery faster as it accelerates the chemical reaction in a cell. We can’t change the weather, but you can try to avoid parking your car under the sun to extend the lifespan of your battery.

Leaving the engine off for too long

This situation probably happened to people who went away for a vacation or couldn’t use their car for whatever reasons for a long time. You try to start your car after a week, but it fails. The reason for this is because the cell also discharges when they’re not in use. If you have to leave your car while you’re away for quite a while, unplug your negative terminal.

You can extend the lifespan of your battery

They say the average lifespan of a car battery is around two years, and you’ll have to replace it. However, a well-maintained cell can last over five years. Keeping your battery and tray clean is one of the ways to maintain your battery’s life.

How you discard your batteries matters

If you replaced your car battery yourself, you can’t just leave it sitting somewhere. This is because car batteries contain lead dioxide and sulphuric acid that harms the environment and poses a risk to your health. Recycle your dead batteries, or take it to your local recycling centre or scrap metal facility to dispose of it.


The lifespan of your car batteries depends on how you take care of your car. If you’re not sure how to maintain them, seek professional help from workshops or car service centres.
