Common questions
Batteries, answered
Can you tell if I just need a charge or a new battery?
Yes. We test the battery and the charging system first, so you only replace it if it's actually the battery and not the alternator or a bad connection.
Do you have my battery on hand?
We carry common sizes and can source the right group size for your vehicle. Tell us your year, make, and model when you book.
What if my car won't start at all?
Let us know where you are. We'll come to you, get you started, and handle the test or replacement on-site.
