Finally! Rechargeable hearing aid batteries that actually work and last at least 12 hours per day. However a little pricey at $70 per piece. But supposed to last a year. Hope so.

Empleada en audífonos Oticon, se recargan cada noche con un cargador específico de Z power.La vida de la pila es de unos 500 ciclos de recarga, tras lo cual pierden capacidad y ya no aguantan todo el dia.Oticon facilita una tapa del audífono que permite recargar la pila sin abrirla, simplemente depositando los audífonos sobre unas cavidadades del cargador, quedando fijados magneticamente.Opción ecologica para quien quiera minimizar los residuos.

Purchased on January 4th and no longer retains a charge less than a month later. I really did like the advantage of the original rechargeable batteries as opposed to the disposable ones, besides being better for the environment. Not having to carry the replaceable ones and sometimes having to replace them in less than ideal conditions, makes the rechargeable one preferable. $70 waste of money!!!!!

The Z power rechargeable hearing aids are working very well. They are brand new. I will be interested to see how long the maintain their ability to recharge fully and provide full charge. My original Z power batteries I got with my hearing aids (got them before the company went bankrupt) lasted for 1.5 years, probably longer than expected. I hope these last that long too. We will see.

The battery drains quickly after 4 months

The hearing aide provider told us they could no longer obtain ZPower batteries. We were most please to find these ZPower batteries on Amazon.While fairly expensive they were cheaper than buying new hearing aides. And they worked as promised

I liked that this product is the same as I used to be able to get but no longer available. It is very important to have rechargeable and dependable batteries for my hearing aids.

The battery life doesn’t last very long. I can get a good 8-10 hours out of them for normal use. Using them for anything else, lowers the life significantly.I love the fact that they are rechargeable. Just wish they would last for more than a day on one charge.
