The designation tells you almost everything here: AA (R6) and AAA (R3) go into remotes and toys, the round CR2430, CR2450 and LR44 button cells into a car key, a scale or a motherboard, while 23A and 6LR61 go into a gate remote and a smoke detector. An alkaline battery generally lasts longer than a zinc-carbon one. Note the number of pieces in the pack as well – the same designation is sold both singly and in tens. A used battery does not belong in household waste, but in a collection box.
