I will probably try that - see if it makes any difference. I know that the
guy
that bought John W.'s Baby Blue, which also had the G31's in it, had
problems with
a couple batteries. But his were prototype, and mine were production run.
They may
not have all the bugs worked out of these yet, which may be why they are
rebuilding
the production line.

We've tried cutting that back - right now, I'm turning the charger off when
it cuts back
to finish, as the Rudman Regs are all up and blinking madly at that point.
This charger
cuts back to finish by itself, and there is a set of dip switches that you
can set to determine
the finish time.

Thanks for your response, David!
