These size 675 hearing aid batteries are 100% mercury free. These hearing aid batteries are 1.45 volts. There are 6 batteries per package and they have a 3 year shelf life, but when activated (tab is removed) shelf life becomes much shorter.
They have never failed me on product or delivery the best.
