I'm looking for a good charger for my PowerSonic AGM batteries. I have a car charger, but that seems to be malfunctioning, as it doesn't seem to want to charge car batteries or my glider batteries. Any recommendations on a good charger for these type of batteries?

I have gone to the Hitec X2 AC Plus. It charges most chemistry's include lead-acid and lithium iron, and operates off of either AC or DC power sources.. I use it along with donor batteries to charge my ASH31Mi batteries while tied down on the ramp w/o any AC power. It can also do discharge testing.
