The chargers I posted about are designed for automotive use. I've used some form of this charter for 5+ years with no problem. The do have three selections, 6v/12v, std/agm/gel, and 2A/6A. Then when the light turns green as fully charged they switch to trickle mode. Best bang for the buck. We are able to keep 12 batteries fully charged at events with 4 chargers.
