Frequently Asked Questions

How long should a car battery last?

Typically 3 to 5 years. Hot climates shorten battery life. Cold weather is when weak batteries usually die.

Do I need an AGM battery?

Only if your car came with one or has a start-stop system. Otherwise a standard flooded battery is fine and much cheaper.
