Is your car starting to sound lazy when you are starting it? Your battery may need to be tested.
A car battery is designed to last the average vehicle 5-7 years. However problems with the charging system or corrosion can cause a battery to fail sooner. Most vehicles also have a battery indicator light on the dash that lets the driver know if there is a problem with the battery. If the battery is old, it is best to change the battery. A mechanic can test the condition of your battery to let you know the current life left in your battery.
