Here I go again with another query about how the real world (outside the USA) uses a word. Hereabouts, the term, "battery" seems to mean any electric cell or group of cells, whereas its original meaning indicates a group of two or more cells linked together. How is it elsewhere? My curmudgeonly self rebels against this loose usage, but I'm being overwhelmed by popular usage. HELP!

BTW, I do understand that two or more people linked together can lead to battery, but I'm not assailing that definition.
