### Power Capacity and Power Capability

2013 2 16 The way the power capability is measured is in C s.A C is the Amp hour capacity divided by 1 hour So the C of a 2Ah battery is 2A.The amount of current a battery likes to have drawn from it is measured in C.The higher the C the more current you can draw from the battery without exhausting it prematurely Lead acid batteries can have very high C values 10C or higher and lithium coin
