Re: (ET) Electrolyte circulation

My thought on it is it would be easy to get a leak and
spill out all one's batterys' acid that way. Advantages
of recirculation could include keeping all batteries at the same
temperature by heating or cooling the electrolyte and
filtering out any precipitate from the solution and
probably reducing the frequency of equalizing charges.
I have not heard of this being done, but it should
be possible. In an emergency, a quick "charge" could
be had by replacing the electrolyte (shortening battery
life, though). I tend to prefer low tech solutions to
low tech problems such as cutting the grass and tilling.
Perhaps this could help a bit with snow blowing where
the temperature is way too low for conventional lead
acid batteries. It has not gotten that cold around me
for the last twenty five years. A low tech solution would
be letting the batteries charge and warm up in a warm
garage or using battery heaters (or heat from the 
elec-trac charger) to warm the batteries
while charging. There's not much room for insulation
around them in an elec-trac, I don't think. A higher
tech solution could be to warm the electrolyte while it
circulates. It might be possible to reduce charging
time this way, too, where that is critical (like on a
drag racing strip between races or a tractor pull between
pulls). A very high rate of charge might be accepted
by the batteries if the electrolyte is kept at an
ideal temperature. The specific gravity could be monitored
for all the batteries on a continuous basis for very
precise state of charge monitoring. Hmmm. Very interesting
possibilities here...
Thank you.
