Aviation Consumer in January 2008 ( <http://www.aviationconsumer.com/issues/38_1/maintenancematters/5741-1.html> http://www.aviationconsumer.com/issues/38_1/maintenancematters/5741-1.html, must be subscriber to read link) did a review of batteries. The headline reads "In flooded designs, Gill and Concorde are close. But owners complain—and our tests show—that Gill sealed models aren’t as long-lived as the Concordes." I tried a couple of Gill sealed batteries and they didn't last more than 2 years. Now have a Concorde sealed battery going past 2 years and it's as strong as when new. With the battery almost right over the spar, I won't use anything other than a sealed battery.

I typically have replaced the G35 in My Cessna 182 every three years at annual time. However the one I installed last year was not holding residual charge so I contacted Gill. I learned a lot about aircraft batteries from that call and a number of follow-up calls. In particular, I learned of the many differences between aircraft batteries and car/motorcycle batteries. Aircraft batteries are designed to operate at a higher voltage and must be charged accordingly. Gill ended up replacing my 182 battery under warranty, but I expect the problem was more related to improper charging than it was to the battery having a factory defect. If anyone is having problems with a Gill battery, I suggest they contact Hector Vara at Gill Customer Service 800-456-0070 . <http://geo.yahoo.com/serv?s=97359714/grpId=19286938/grpspId=1705340085/msgId=6964/stime=1228076062/nc1=4430620/nc2=3848627/nc3=4507179>
