This slow trickle charger is the best way to charge your batteries. We are an Interstate Battery dealer and we are told that batteries should be slow charged at no more than 2 amps in order to extend the battery life and to get them to maximum charge levels. The slow charge also protects the battery from over charging and the damage that it can cause to your battery. If your battery is not used for long periods of time then a 2 amp trickle charger is what you need! 714-568-0187 store, 1-877-dinghys, 714-724-1479 cell |
