8. Standby Discharge Factor (SDF) = _________ Alarm Discharge Factor (ADF) =
_________
9. Minimum required battery capacity calculation for a final discharge voltage of 20.4V (to
account for battery aging, a 1.17 multiplier is included).
Minimum battery capacity in Ah =
1.17 x [(A x C x SDF) + (0.0167 x B x D x ADF)] = _______
10. Minimum required battery capacity calculation for a final discharge voltage: 23V.
1.32 × [(A × C × SDF) + (0.0167 × B × D × ADF)] = _______
11. If the battery size initially selected is smaller than the result of step 9 above, repeat the
calculations using a larger battery size.
