It may vary according to its usage. To improve the lifespan of a car battery, it’s very important to take good care of it and get its service done every month.

Signs Your Car Battery Needs Replacement

Here are a few signs that show your car battery is failing. 

1) Slow Engine Startup

2) Ignition Clicking Sound

4) The Check-Engine Light

The “check engine” light on a car’s dashboard shows that something’s wrong with the car. It also turns on when the battery gets too weak. So it’s recommended to keep a check on this light, and if it’s on, get your car battery checked by any nearby service center.

Many times, because of internal chemical reactions or exposure to extreme temperatures, the battery case puffs up, gets cracked, or becomes out of shape. This is an indicator that most probably your battery isn’t working properly.

6) Decreased Fluid Level

The fluid level of a battery matters a lot. If it isn’t correct, your battery may not work properly and get damaged soon. This level should be equal to the height of lead plates in the battery, if it’s below the lead conductors, ‌get it refilled, and also get your car dynamo checked.

7) Leakage

Leakage is another signal of a dying battery. Many times, the fluid inside the battery leaks out from the terminals. This causes corrosion and the car engine may not start due to the lack of conductivity.

9) Damaged Terminals

Because of the leakage of gases and fluid from the battery, the terminals become corroded and damage slowly. This shows that the battery isn’t working fine, and you must replace it.

10) Old Age Battery

If your battery is too old, and you haven’t replaced it for a long time, ‌get it changed as old batteries can’t properly ‌start the engine and run other electrical components in your car. Anytime, you can face inconvenience due to a battery failure.
