Middle English : from Old French baterie , from battre to strike, from Latin battuere . The original sense was metal articles wrought by hammering , later a number of pieces of artillery used together , which led to the meaning a number of Leyden jars connected up so as to discharge simultaneously (mid 18th cent.), giving rise to sense 1. The more general meanings date from the late 19th cent.
