Calculate power (Watt)

Potential ?	3.85 V (Volt)
Current ?	36.08 A (Ampere)	A = C/s
Resistance ?	0.11 Ω (Ohm)	Ω = V / A
Active power ?	138.89 W (Watt)	rate of energy transfer / W = V * A

Calculate energy (KWh/Joule)

After 1 hours of continuous power usage:

Charge (Ah)	36.08 Ah
Energy (kWh)	138.89 Wh
Energy (Joule)	500.01 MJ
Energy (Calorie)	119.42 Mcal

Calculate capacity (mAh/Wh)

Compare capacity with [AA batteries] [Powerpack] [Phone]
