Calculate Battery Capacity, Discharge Time using Peukert's Law


The calculator finds the full discharge time and actual battery capacity based on Peukert's Law.

 
Rated Battery Capacity (C) : amp-hours
Rate of Discharge (I): amps
Peukert's Number (n) :

 

 

 

Actual Battery Capacity : amp-hours
Full Discharge Time (T) : hours
How long a battery could Last through Peukert’s Law means calculation of full discharge time. The battery capacity refers to the amount of energy it may store.

Formula:

Actual Battery Capacity = (C x I) / In,

Peukert's Formula, T = C / In

Where,

C = Rated Battery Capacity,

I = Rate of Discharge,

n = Peukert's Number,

T = Full Discharge Time
