The signs to look for
how can you know if your car battery needs replacement
Engine won't start or slow crank
When you turn the key, the engine may not crank at all, or it may crank very slowly and weakly.
Dim headlights:
Headlights that are noticeably dimmer than usual, especially when the engine is not running, can indicate a lack of power from the battery.
Warning light
The battery warning light on your dashboard, usually shaped like a battery, will illuminate when the battery is not charging properly or has an internal problem.
Electrical issues
Other electrical components like the radio, interior lights, power windows, and even the dashboard lights may not work or may malfunction.
Strange smells
A rotten egg smell coming from the battery area can indicate a battery leak, which could be a sign of a dead or failing battery.
Swollen battery
If the battery case appears swollen or bulging, it's a clear sign of a problem and should be replaced.
Recent jump start
If you've recently needed a jump start to get your car running, it could indicate that your battery is nearing the end of its life or has a significant issue.
