Specific Power in a battery

Specific Power in a battery refers to the maximum power the battery can deliver in relation to its size.  Its unit is W/kg.  Specific Power is an important parameter in applications such as aircraft where weight of the battery in relation to its power capacity is important.  Mobile Phone batteries,too, will have a high power to weight ratio.

A battery with a high specific power value will deliver more power while having very less weight.
