This makes for a nice synopsis concerning SOC and voltage readings to
be expected from a variety of lead acid battery types.

With thanks to RJ, Dave and Paul it appears my battery
pack is healthy. Had checked spg early on and again today....1.3 or
greater in all cells.
Cheers, Jack

No problem that I can see. Once everyone is well broken
in slightly longer charging cycles will put the numbers where you'd
like to see them.The equalization phase of charging may not have been
completed when you checked them.
Of course the ultimate Luddite weapon for determining state of
charge is the nice messy hydrometer.............................

Have a new pack of T-105's as of January
'08. At that time got a new capacitor from Harold for the onboard
charger. The first 13 charge cycles registered 45v or a bit higher
over an 18 hr charge time. I was happy. The next 9 charge cycles, up
till today, register 44.4-44.6v. My understanding is that a healthy
pack must have a finish charge of 45v. Load test with mower running
gave me 6.08v and 6.09v for the two front batteries and 6.13-6.19v for
the four rear batteries. Do I have a problem?
Thanks,
Jack
