Common questions
How long does a car battery last?
Most car batteries last 3 to 5 years. Heat, short trips and lots of electronics shorten that, so a battery that is 4 years old is worth testing before winter.
Can a bad alternator kill a new battery?
Yes. If the alternator isn't charging, a new battery will go flat too, so ask for a charging test.
Why does my car need an AGM battery?
Cars with start-stop or lots of electronics are built for AGM batteries, which cost more but handle repeated starts better.
