<DIV><FONT size=2 face=Calibri>We have seen one failure mode with sealed
batteries that stands out, and that is long term overcharging. Two reasons
for that, one is from failing to set the correct charging voltage, but another
main one is not using temperature compensation. The charging voltage for
batteries should go down quite a bit at higher temperatures - but without
temp comp that won't happen. If you boil flooded batteries you can add water,
with sealed batteries not so easy.</FONT></DIV>

echo your results on the addition [per manufacturer’s directions] of distilled
water and application of a deep re-charge [eq.] charge, I got 4 to 6 months on
the 3 banks that we attempted to revive. If we think wet lead acid batteries
are a fragile chemical equation then sealed batteries are even more
fragile.<o:p></o:p></SPAN></P>
