By multiplying 2 Amps x 120 Volts, you find out the refrigerator uses 240 Watts. The batteries will need to deliver 20 Amps to run the refrigerator (240 Watts/12 Volts = 20 Amps). Typically, refrigerators operate about 1/3 of the time (1/3 duty cycle), or 8 hours a day.Therefore, the A.H. drain will be 160 A.H.(8 hours x 20 Amps = 160 A.H.). After the load and running time is established, the battery bank size can be calculated.ypically, refrigerators operate about 1/3 of the time (1/3 duty cycle), or 8 hours a day. Therefore, the A.H. drain will be 160 A.H. (8 hours x 20 Amps = 160 A.H.). After the load and running time is established, the battery bank size can be calculated.
