Formula and Equations for Battery Life Calculator

life = (Battery Capacity/ Load Current) ×
Battery Life = (Ah rating of Battery / Amp) x Run Time %
life = in Hours
Capacity = in mAH (milli Ampere hours)
Current = Consumption of device in Amperes
= Battery
Cycle life
considerations (Run Time)

Note: In ideal case, the battery life formula would be;
life = (Battery Capacity in Ah/ Load Current)
