It determines the battery weight required to achieve a given performance target. • Energy Density (Wh/L) – The nominal battery energy per unit volume, sometimes ...
Power Capacity and Power Capability | All About Batteries
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 …
