| A fully charged battery will read 12.86 volts. You're a bit low. Hard to tell if your reserve is holding up or not. I'd get it tested.
Optis do have a slight draw when sitting. I had my battery go down over a couple of weeks one winter when the charger got unplugged.
1000 MCA is spec'd for Optimax. That works out to about 785 CCA. MCA X .785 =CCA
Even though your battery can turn the motor over, it may not allow it to start it. Seen it on EFI's too. Cranks fine, but no fire. Jumper from TM batts, and started right up. | |
