Battery Info

[soccerman]

How do I find out info on my batteries? I have two stock batteries in my truck and I want to have them tested. In order for me to know if they are bad, I need to know what output it should have before doing a load test. Don't really want to replace batteries this close to xmas but if it saves me from walking to work, i'll do it. I'm guessing the main number i'm looking for would be the cold cracking amps?! Correct me if i'm wrong.

There should be a sticker on the front that tells you the CA and CCA. CCA is what is more important but you don't have to know the CCA to have a load test done. Stock batteries should be around 800 CCA each.

Most batteries tell you on them, they will be rated in cramming amps (32*) and cold cramming amps (0*). The higher the better, and any advance or autozone can do a simple load test on them, in the truck. I know the batteries advance sells are rated at 850 cca. Iirc the motorcraft are slightly less...could be wrong. You'll have to disconnect them, to test them one at a time.

You'll want to make sure that you aren't running around on low batteries, or with a poorly charging system, from my research and talking to various Ford techs its detrimental to the ficm. Good luck.
