with 40AH or 48AH charger installed and some 36AH charger installed.
I'm not familiar with the "AH" rating for battery
chargers. Usually
battery capacity is measured in AH (ampere hours). On our aircraft, the battery charger, in TRU mode, can supply up to 65amps. We only have a single 48AH battery. Some airlines have dual 48AH batteries. If you have different battery capacities, perhaps you should consult Maintenance, especially for MELs.
