RayovacL312ZA-80ZM Mercury Free Hearing Aid Battery, Size 312, 80- Count

Price is great and product SUPER !

They work very goog I put them in and got 8 days 7 nights of nonstop usage from them ! They are well worth the price shipping was fast as well . I have found my new battery!

great product, good price.

Opened the first pack a few minutes ago. The 1st two sets did not work and threw them away. The 3rd set of batteries did work. Wonder how the rest of the 1st pack and/or the other 2 packs will work. Not pleased. UPDATE: OF THE FIRST 8 IN THE 1ST PACK, ONLY 3 WORKED.

We use this size battery for my Mom's hearing aids, she often cannot find them locally, when we do the price is astronomical when compared to this deal!! The price at the Hearing Center where she regularly goes... Ridiculous!! Shameful!! They take such advantage of the elderly, esp. those who have limited options due to age (83yrs) and living in a rural area... Thank You Amazon & your retailers/sellers for helping so many people with your prices & convenience!!!

as expected

Just what I needed,

Used for a hearing aid long-lasting thank you A+++++ seller

Consistently don't last 5 days. I would not repeat this experience.

Some of the longest lasting I have come across - a bit more than a week for me. I have nad issues with some no-name or private label batteries, but every one of these worked perfectly (even if I didn't let the battery 'breathe' for a minute after removing the tab before closing up the hearing aid. Great value for the money

5 stars

I like it , for the longer time it takes, but no way will I pay , the amount ask by the vender. Thank you.

did not read the full description, my bad, will look closer next time
