B737-NG Battery drain

Can anyone remember from the sim ( or real life I guess) what one would expect to see on the metering panel with BAT selected if you suddenly lose both generators and the APU is not running?
Another way of putting it is how many amp-hours is the battery?
( single battery aircraft) I can't find it in the FCOM.

36 amp/hr and I seem to recall about 72 amp/hr drain, so pretty much 30mins!

Each battery on the NG provides 48 Amps/hr if fully charged.
