DuracellActivair Size 10 Hearing Aid Battery with 60 Batteries

Great price, great product & very quick service.

I normally swop between these and Rayovac. For some reason, after two weeks, the Rayovac hadn't even been despatched so I ordered these which arrived in 2 days. I like the little cases they come in as they can be transported in pockets, bags etc. without fear the batteries will fall out and maybe get into the hands of a child or the mouth of a pet. I like the long tail on the little paper tab as it makes the battery much easier to insert. I get about 4-5 days use from them, which I think is about average, although there is the odd dud or one that does not last quite as long. I only found out a few months ago that these batteries need to be left out of the package for about 5 minutes before inserting as that can prolong the battery life. That's the whole point of the term Activair. Here's the science bit - metal–air batteries are powered by oxidizing zinc with oxygen from the air. My audiologist didn't tell me and as I'd had free batteries with my aids for a long time, it didn't occur to me to check out the product description on the web site. I don't think that fact is mentioned on the product itself nor here, unless my eyes are worse than I thought. So now, when changing my batteries, I take the paper tab off for 5 minutes then put it back on to help me insert the battery. Job done.

Very good battery life , power consumption last for a couple of days depending on usage

l used for the purpose they were made

Very pleased with the batteries. Fit perfectly and are easy to install

I used only one and it lasted very well

I usually use rayovac batteries in my hearing aid but these have proved a very good alternative. Super fast delivery too!

needed some, but have since changed hearing aids to behind the ear blue tooth versions which work a lot better.
