Just back from the Shanghai solar show (SNEC) which featured mostly Chinese manufacturers, mostly offering grid-tie product. But I noticed quite a few battery manufacturers who were proud to tell me they are now making gel batteries. It seems the market is learning the value of a good gel battery for cyclic (deep cycle) applications. We hope that this is partly due to the great performance of the Deka gel battery over the years – imitation is the sincerest form of flattery. I didn’t see any 12v gel battery that provided more than about 700 cycles at 50% depth of discharge, but at least most manufacturers were publishing that information. We really need to get customers to start pricing batteries per cycle, rather than per unit. When you buy a battery, all you really buy is cycles…..
