Car Battery Question

[FlamesAddiction]

I just bought a Motomaster Eliminator car battery charger. In the owner's guide, it says to pick a charging rate that depends of the battery "amp hours". The problem is that neither of the batteries that I want to charge has that information on the battery. It has "reserve capacity (125min)", CCA (875a), and amps (1050a).

Does anyone know how to calculate amp hours, or better yet, can anyone tell a reasonable guess as to how many amp hours my battery is? For all I know, maybe most batteries are the same.

Thanks.

All I know is that my charger has two settings for 12 volts. 2 amps and I think 6 amps. I use the 2 amp setting for my motorcycle but I think that's a little to much and I'd be better off with a 1amp setting. The 6 amp setting is for car batteries but for a slower, safer charge I guess the 2 amp setting would do.

it depends if you are looking to do a fast charge or a slow charge...
