From Middle French *batterie, from Old French *batre 'to beat, strike', ultimately from Vulgar Latin *battuere, frequentative of Latin *battuere 'to beat'. The modern meaning developed from the idea of a 'battery' of guns, then extended to electrochemical devices.
Initially referred to a group of cannons, later adopted for electrochemical devices due to the similar arrangement of components.
