View Full Version : Battery Question

04-17-2011, 11:49 AM
I have 2 800 cca Interstate batteries-I had them analyzed yesterday and voltage was fine but the cca's on 1 was 605 and the other 578. I don't feel like buying new batteries and was wondering if the lower cca's is an issue (I feel this is enough to crank boat)?

How old are they?

2006 that I bought 11/07: I never changed the batteries. I guess I am reluctant since volts are fine

If it was my boat, I would run them until I had a problem.

Assuming you have a dual battery system where you can run the batteries in parallel, you currently have almost 1200 CCA's.
