Well the performance certainly increased! When I got to work, the voltage was over 73v-never been that high. Voltage never sagged below 60v which was also a first. On the way home, about 1/2 block from my house, I heard a pfffft sound and voltage dropped to about 34v. I pushed the car the rest of the way home. All batteries showed their highest ever, none below 12.22v, even though performance was noticeably improved. So I put my blower to each battery and sure enough, one of the Orbitals would barely make it turn
I was so excited too. Man, could you imagine what 6 brand new Orbitals would be like in my car??
Anyway, at least the other one is doing ok.
Pack voltage 75.3v
Dead Orbital 12.62v
