We highly recommend any name brand of Three Stage Smart Chargers for ALL AGM batteries! Do NOT use CSI, Schumacher or Sears constant current chargers with AGM batteries unless you pay for the AGM modification. Most all other SMART 3 Stage Chargers do fine! Here is a partial listing of some of our loyal friends.
