I still wander off into the back woods of colorado now and again. Isn't there a childrens book "Where the Grid Ends, the Fun Begins"?

I'll let you know what I find out.I realize most wrenches are grid tie installers. How many off grid battery wrenches are on the list?

My local battery “superstore” (everything from cell phone to golf carts) had been using them for the last few years to test automotive starter batteries and deep cycles but the last time I was in there I noticed they’d gone back to the old standby resistance/carbon pile style testers. I inquired and wasn’t able to get any exacts but the summary was they were not happy with them. I’m curious to know your findings on both fronts.

If so, what do you have and how has it worked out. I have seen prices from $200 to $7500 and I'm sure there is a world of difference. I have been using a pulser circuit I built about 4 years ago to restore nearly dead AGM batteries but I have not had any sophisticated method of verifying before and after performance. I perform a constant current equalization with no voltage limit and then leave the battery on the pulser for a few weeks. This works great and I have restored and sold a few used AGM batteries that would have gone to the recycler. Today our battery buyer just picked up another 15,400 lb. of batteries from us. Yep, they were mostly murdered! I would like to be able to restore more of them. _______________________________________________ List sponsored by Home Power magazine List Address: [email protected] Options & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org
