AMP-HOURS

If the current draw at 120 VAC is known, then the battery amperage at 12VDC will be 10 times the AC
amperage divided by the efficiency (90% in this table).

Motors are normally marked with their running rather than their starting current. Starting current can be
five times running current. Keep this in mind when sizing a motor into a system.

Refrigerators and icemakers typically run about 1/3 of the time. Therefore, their average battery current
draw is 1/3 what their amp rating would indicate.
