Question:
I was told that antinmony was added to the plates to
make them stronger to take vibration which fork lifts
and floor scrubbers might get. But RE systems should
not get.  I also believe the antinmony causes the high
self discharge rates.  So would not Lead calcium with
much lower self discharge rates and less need cycling
be better?

Tom in your case what was the configuration that
caused the earily failure?  So I can avoid.
