Unusual man's watch |
LR44 is a fatter 5.37 mm version of an LR43 x.xx mm My
measuring callipers use LR44 The slimmer larger diameter
cells, eg CR1620 for mens watches & PC main boards are
Lithium, 3.0 Volts.
Probably chemically more dangerous to humans, & cost a
lot more,
more usually bought individually, but late 2020 Conrad.DE
had assortment packs.
