Most people here drive to campsites and plug into 120v. So the batteries never get cycled. Never see a strong charge. Sits there on solar and ruins the flooded battery.
If that same person did not have solar their batteries would self discharge and then get recharged at a high amp rate. Which i think would improve the life of the battery. Sitting there on float all day is no bueno. From what ive read on the trojan website regarding flooded batteries.
Makes me think some of those bad costco reviews are probably from people with solar hooked up and never give the battery a proper charge.
