If you are going to use actual wet lead-acid batteries, there are replacement catalytic call caps that recombine the O2 and H2 so that the water isn't lost, but drips back into the cell. The 'home power' crowd swears by them. Some water is lost but apparently not much. _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list
