Signs That You Need a New Car Battery
There are several signs that indicate your car battery needs to be replaced. Here are some common indicators:
1. Age of the Battery
A car battery typically lasts for around 5-7 years, depending on the type and quality of the battery, as well as how well it is maintained. If your battery is approaching or has exceeded its recommended lifespan, it may be time to consider replacing it.
