K & T Ballina Mechanical • September 23, 2022

A good battery is crucial to a good vehicle. Not only does it help your engine to start, but it also powers all electrical components within your car. If your battery isn't performing at its best, you won't have much success heading out on the road. How do you know when your battery needs replacing? Read on to learn more about the seven top signs it's time to get a new one.

1. Slow Starts

2. Electrical Troubles

Your battery's responsible for powering all your vehicle's electronics. If it's on the way out, your electronics won't be able to operate at full capacity. And if you plug things into your car while on the road, such as your phone charger, your battery will succumb more quickly.

3. Illuminated Light

The check engine light basically means just that - check your engine. It can be triggered by just about anything, including a dying battery. If you notice the light coming on in your car, check your manual and organise a professional assessment of your battery.

4. Unpleasant Smell

If your battery is damaged, it can start leaking gas with an unpleasant rotten egg smell. If you get a whiff when you open your bonnet, you may have a leaky battery on your hands. Get it inspected by a professional mechanic, who will let you know if your battery's to blame.

5. Corrosion

If you open your bonnet and see a white powder on the metal components of your battery, you have corrosion on your hands. If your battery's terminals - the positive and negative connections at the top of the battery - are corroded, you'll experience problems with voltage and starting your vehicle.

6. Swelling Or Cracking

Your battery case can swell or crack in extreme heat or cold. If your battery looks an unusual shape, it most likely won't be working properly.

7. Age

Can't remember when you last checked or replaced your battery? You're not alone. Batteries usually last between three and five years in the best conditions, but climate, electronic demand and driving style all have a part to play in its longevity. It's a good idea to test your battery's performance regularly as it nears three years of life.
