I purchased this for camping to power an inverter. It lasted the 4 nights we camped, with no problems.
Used this battery weekly since June 2013 for the trolling motor on my boat ~ never a problem and has always charged to 100%. Typically fish for 4 to 5 hours each time out using trolling motor exclusively ~ always performed well.
Exchanged last year for same type as the one year old would not charge up. Bought another so with two of the same they were used once to run outboard in early fall. They were taken out and stored under house on wood in a heated area. This spring retrieved them and tried to charge them up. The one brought in Oct.2014 charged 100%, the other one that was exchanged for the 2013 dud did not charge beyond 60%. In brief used only once, stored properly and charged correctly yet duds. Not worth it, not a reliable battery to say the least.
