These Sony hearing aid batteries are replacement batteries for size 13 hearing aid batteries. These hearing aid batteries are 1.45 volts. There are 60 batteries total per box and they have a 3 year shelf life, but when activated (tab is removed) shelf life becomes much shorter.
Good product, right price, timely delivery. :>)
Fast, on time shipment.
I bought these batteries for my 93 year old mother. Everything about batteries are five star. Price, longevity, fast delievery etc. Bought two- 60 packs dirt cheap, and have a years supply for her. That's my way of doing business. If all things stay the same "I'll be back", like the Terminator.
I had bought Hearing Batteries from Battery Mart before and I like the price and the Batteries worked really well, so I'm back again for more. Thank you very much J Frost
