https://sfsailing.com Marine Business Index - TROJAN BATTERY CO. en-us Copyright 4 sfsailing.com https://backend.userland.com/rss/ Tue, 21 Apr 2026 01:40:41 PST I have a gemcar it`s kind of like a golf cart. In March I purchased 6 new Trojan batteries and installed them. They were fine for awhile but now when they are at about 80% 3 of them go bad. When I put a load tester on the 6 of them 3 read good. The other 3 read bad or weak. Note: You will not find this reading if they have been charging overnight. It`s just when their down a little bit?I`m taking them back and run the Gemcar up and down their street untill the simptom occurs so they will see for themselves. {ts '2008-12-28 08:08:00'} 08:08:00 PST
