Rayovac Extra Advanced Mercury Free Hearing Aid Batteries Size 13 + Battery Holder Keychain Kit (40 Batteries)

Meet our expectations .

Duh

Batteries were no good and I returned them. Ups picked them up already and amazon wants to charge me again for no return. I did return them.I recommend not to order these.

I have only used these batteries for a short time, but so far so good. If one must have hearing aids, as I now do, it seems these are as handy as any, and I do like the way they are packed and come out so easily from the little hole in the back.

Love these batteries they last a long time.

I was looking for an alternative battery for my hearing aids that gave me 7 days of service without fail. My current brand had begun to at 6.5 days every 4 weeks. Nothing worse than having to change batteries in the middle of a meeting, or disconnect it and strain to hear what is being said.I read a few people say they had tried another brand, but we’re going back to Rayovac. So I tried a box and in the first package had one that appeared to be a dud. Would not boot either hearing aid, checked it later with a multimeter.I had a number of batteries give out in 3-4 days. I’m back to my previous brand and I’m back to working at home. Battery change during Zoom is of a problem.

My mom must use these for her hearing aids and they need changing fairly often. They are very pricey in stores, so we tried Amazon. GREAT PRICE for these batteries. Bravo for providing a decent price.

Unfortunately, the performance of these batteries is erratic. Several "died" either before use or within minutes after inserting them in the hearing aid. Others were fine and performed normally for the expected life of the battery. The uncertainty, though, is nerve wracking because one never knows when the ominous tones signaling "dead battery coming up" will sound and one will have to change the battery to continue a conversation. I won't purchase this brand again.

Excelente servicio y mi pedido muy bien
