One charged with physical attack? (7)

I believe the answer is:

battery

I'm a little stuck... Click here to teach me more about this clue!

'attack?' is the definition.
(I know that battery is a type of assault)

I don't understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for battery that I've seen before include "Group of cells (or guns)" , "Storage cell" , "Source of stored energy" , "crime" , "associated with assault" .)

I've seen this clue in The Sun.
