Optima Trials and Tribulations
- Well, my luck with Optima batteries continues.
History so far:
Bought 13 Optima BlueTops.
2 were bad and had to be shipped back for replacement.
The 2 replacements showed up, and 1 of those was bad.
The replacement for that showed up - and the shipper had dropped it.
The replacement for that finally showed up (after an odd delay in
shipping) and seems to be good.
I did a few light cycles of the new battery on the bench to bring it to
close to the rest of the pack. (only had about 6 cycles on the pack so
Note that the Sparrow has sat with the BRB pressed, and one battery out
with cables disconnected for a month. The only load on the batteries
were some MKIIC regs.
I hooked in the new battery, and turned on the PFC40. 9 of the regs
immediately lit up. Of the 4 "low" ones, the new one and 2 others were
about .2v below the reg point. So I've put those on a small charger to
top them off.
The problem is the 4th low battery. It was QUITE low. Like at 13V or so.
So I put 12A charger on it. (Standard car battery charger). Set to AGM
and 12A charge rate. Charger said the battery was at 51%.
2 hours later, it's at 65%. 3 hours it's still at 65%.
