PowerOne ACCU plus Size 312 Rechargeable Hearing Aid Batteries, Model: Size 312 2-Pack, Electronic Store & More

I have a pair of Siemens hearing aid that are about 15 years old. Four years ago I took them in for my annual hearing test and hearing aid check up. One hearing aid was not charging. I was told they no longer serviced this hearing aid. They set in the drawer until last week when I made one final try before discarding them. I received my new 312 batteries, put them in the hearing aids and charged them over night. Indicator light showed one was charged the otherwise not. Tried the charged one, worked fine. Switched batteries, the one that did not work still did not work. Put them back in the charger and after two more days the indicators come on and both hearing aids worked. What happened and why I don't know. All I do know is these batteries sure saved me a lot of money.

I like these rechargeable hearing aid batteries!!

Hearing aids started working properly again after inserting new batteries. It's a miracle !!

These were rechargeable batteries but would not charge in my Beltone Hearing Aid charger. Batteries no longer have a charge after only several hours of use. Will not buy these again

Does not work with Oticon

Always nice to have rechargeable batteries in any thing you buy. I have recently bought new hearing aids with built in lithium batteries.

Batteries don't hold a charge very long.

great for hearing aids
