Battery Life Calculator

Formula and Equations for Battery Life Calculator

Battery life = (Battery Capacity/ Load Current) × 0.7

Battery Life = (Ah rating of Battery / Amp) x Run Time %

Where;

• Battery life = in Hours
• Battery Capacity = in mAH (milli Ampere hours)
• Load Current = Consumption of device in Amperes
• 0.7 = Battery Cycle life considerations (Run Time)

Note: In ideal case, the battery life formula would be;

Battery life = (Battery Capacity in Ah/ Load Current)
