Working great, thank you!

Disappointed at duration of hearing aid batteries. With my test on daily usage 9am-10:30 pm, batteries lasted 8 days, where RAYOVAC 312 lasted 10 to 12 days.

Bought for my hearing aid and they work great. Seem to last longer than what I get at the store.

Having tried all other makes of batteries that failed I am happy that these German made batteries are superior and they out perform all the other batteries . I would recommend these batteries to all hearing aid users . Great value for money.

Great batteries, mercury free and they seem to last longer than the other brands that I have used.

Great value! Keep my hearing aids operating smoothly.

I have tried others for at least 15 years and these are the best so far. I am exceedingly pleased with these batteries!.

Reasonably priced and long lasting, what else can I say...!

Great and simple to use product....usually lasts me about 5 to six days per battery. I always need to remember to change both batteries at the same time even if only one has indicated it's about to run out.

I think the batteries are stronger and last longer. They help me to hear better.

I have used this product before and it has worked well for my hearing aids. They arrived quickly after purchasing and were in good shape.

This was the best price I could find for these excellent batteries!

Better 2 than 1, which is too few.

Lasted 4 days. My "one of the best known brands" batteries, a day and a half. And the price really clinches the deal.

These work better than the ones I was getting @ Walmart. Why? I dont know..

Having used this battery in the past, I have received very good performance from them. I have tried others and some were good but did not seem to last as long.

I wear my hearing aids all day long and the batteries last about 2 or 3 days which is what my audiologist told me to expect, so I was not disappointed

Great hearing aid battery.
