Trace 4000 SW vs. 1HP 220v well pump [RE-wrenches]

Kurt,
It really seems to depend on how long you hold the batts at a highly 
gassing voltage. A byproduct of the recombination is heat. The Hcaps 
are made of plastic. I've seen them melt and/or get droopy before, 
but that was usually in conjunction with a bad cell in an old battery 
pack. C20 should be fine. What old George says is don't let the caps 
get too hot to hold. Fair enough. If you are going to leave them on 
during EQ, I monitor them by touching them all from time to time. Of 
course, I'm from California and a touchy-feely kinda guy anyway. 
Maybe in the Midwest folks might look at you a little funny....
Richard Perez taught me a trick with Hcaps years ago. If you've still 
got cold ones during an EQ, those cells aren't gassing as much as the 
ones where the caps are warmer. Keep going! Once all the caps are 
warm, all the cells are gassing merrily. Shut the genny off and quit 
burning the gas!
The other thing to remember with Hcaps is that the catalysis is 
sacrificial. It's only good for so much gas. With a PV system 
charging at between C-30 and C-40, that's about a battery life and a 
half. On the other hand, I've seen some to-die-for hydro systems go 
through a set of Hcaps in three years if the charge controller is set 
too high. I'm guessing a big wind system would do the same.
Best, Bob-O
