B-738 Dual or single battery?

[Manicured garden]

Hello friends.
ELEC Light MEL instructions depends on the type of a/c. Some 738s have dual batteries, some single battery with 40AH or 48AH charger installed and some 36AH charger installed. I can get the correct info from AML but does anyone know how to understand what kind of battery we have on the plane in a quick way?

Thanks in advance.

Take a look on the P5 Panel. If the DC Meter Selector have the position "AUX BAT", you have 2 batteries.

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.
