As it is with every device that needs charging, your car batteries will decrease in efficiency with every charge. With proper care, car batteries can last for more than five years! However, if you use your car daily under average conditions, it would be good to replace it after three years. Beyond this point, most car batteries won’t be as reliable and could lead to a number of safety issues.
The average lifespan of a car battery can be affected by:
1) Climate conditions
Super-hot or cold temperatures will harm your battery. Living in extreme temperatures will mean you might have to replace your batteries more often than advised.
2) Driving habits
Repeated short drives for daily commutes, for instance, could shorten your battery’s lifespan because there won’t be much time for full recharges between drives. On the other hand, letting your car idle in the garage or a parking lot for too long could also drain your batteries.
