Thank you for the help.
I brought the battery home and put it on the charger, disconnected at full charge (I believe it was in the 2.6 range), checked it 24 hours later and it is now measuring 2.40. is the .2+ drop an acceptable drop? The battery is from Walmart, I guess I could have them check it but I don't want another Walmart battery.
You're saying "2.6" and "2.4," but I assume you mean 12.6 and 12.4? If that's right, then no, something is wrong. I don't have my tables with me, but I think 12.4 volts is about 25% discharged, which shouldn't happen overnight. Sounds to me like the battery is defective.

Yes I meant "12" and not "2", I took it to walmart and had them test it. They said it was good, they charged it to 12.58 vdc and the CCA of 775 out of 850. I can't believe it is good though. I installed it back into the MH for and checked the draw again and was still at less than .9 milli amp, so in the next week I expect it to be low again.
