We've been fully charging about every 2-3 days of late, due to work
we've been doing which requires the Honda, and yesterday I fully charged
(one hour at 14.1V or better) and equalized (2 hours at 15.2V or
better), and immediately read the batteries with a
temperature-compensated hydrometer and also our voltmeter, at the end,
while still charging, the individual battery voltages (ya, I know - they weren't disconnected).
The 4 had divergent readings at the end of the equalization cycle: 8.0,
7.3, 7.33 and 6.68 volts. The banks/pairs are 1/4 and 2/3, and, cumulatively, the banks had the same readings, but with very different
single readings. I suppose that could be laid to the fact that I
couldn't effectively disconnect them, but it's still pretty weird...
Temperatures were very different between banks one and two (read down
each water-fill hole; I've averaged the 3 readings per battery)
immediately after equalization:75, 98, 100, 73F - from which I
gather/intuit that bank one (1/4) got much less amperage, somehow, or
there was some problem in bank 2.
