I have a small battery-operated calculator that I rarely use, but when
I do need it, I want to be sure the battery hasn't run down. The
button cell can be a LR54, LR1130, D189, RW89, 389, SR54, or one of
several other codes, Either silver or alkaline. Does anyone know
which type of battery has the lowest internal self-discharge?
