Power One PO-312 Zinc Air Hearing Aid Batteries (Brown) Size 312 (60 Cells)

These are decent batteries and cheap if you buy in bulk. Power One recommend leaving the battery in air for 5 min before installing it to extend battery life. I'll give it a try. Don't quite have the zeal to carry out a controlled experiment

The batteries are very good and work great with my hearings aids. Some other brands of batteries cause various problem's including cut off, etc.. Usual problem. Packaging was so over zealous it would not fit through my letter box (which is large). Please Amazon, great delivery but save our planet and use less packaging.

I usually use this brand and they work well.

Good enough batteries for the price. No better or worse than others around the same price. The seller recommends that the batteries be aired for five minutes before installing to maximise life, but I did this and didn't notice any improvement over other batteries that I have used. All in all, I would buy these again, but not in preference to others as they all seem similarly effective.

Long lasting battery

Have always bought this product from this company and, hopefully, will continue to do so. They are what they are, they arrive when they should - why would I go elsewhere. Have no hesitation in recommending.

good value product , bought for my elderly neighbour who was very pleased to get at much better value than the high street

The battery life was about a third less than other makes I have had over the years. I normally get 3 days from a battery these are 2 if I am lucky. Saving a few pence has been quite costly. I would have returned but I was into the 4 th packet in a fortnight when I realised as I keep battery’s in various places so I never have far to go to change them. On checking I was very surprised at the usage.

Excellent transaction. Fast delivery, product as described with a 2029 expiration date. Will buy all future batteries through this company. Thank you!

Amazonに頼んだメーカーと、違うメーカー品と同時に、箱が何回開けたのか、知りませんが、外箱はぐちゃぐちゃに、此れがAmazonの仕事か疑い増したが、最近は返品の受付もし無くなって居りますから、ホッポトイテ居りますね。

Sufficiently long expiry date

Perfect and economically priced for my elderly moms hearing aids. Long lasting and a great price!
