The listing, Micronta Battery Tester has ended.
Before you thow away those 'old' batteries, make sure they're really dead. This Micronta (Radio Shack) Battery Tester will help you do just that. It will test any battery from AAA to 9 volts and more, in ranges from 1.5 volts to 22.5 volts. It will even test 'button cell' (watch) batteries. It requires no internal battery of its own. The large analog meter is simple to read: if it's green it's good; if it's red it's dead. happy bidding and God bless.
