How often does a car battery need replacing?
Experts in the automotive industry suggest that changing your car battery every 4-5 years is a good practice for most drivers, but this timeline may be affected by various factors that impact battery life.
Does a battery do anything else other than start my vehicle?
Indeed it does. When the engine is off, the car battery acts as a surge protector for the computer and also powers important equipment such as stereo, lights, wipers, and GPS for brief periods.
