When power is restored after an outage, do the chargers automatically revert to the charge-mode? What is the full range of your chargers in Amp ratings?

The chargers are intelligent enough to test the condition of the battery when power comes back on and then the charger will go into the correct mode - bulk, absorb or maintain. Optimate III is only 600ma this is for maintenance. The AccuMate 6/12V is 1.2amps also for maintenance and small charge situations. The AccuMate Pro 12 V 6A is a 6 amp charger but has a special charging algorithms suited for charging big batteries.
