Wokyo Rechargeable Hearing Aid Batteries and Charger for 312 Hearing Aid Amplifiers, Battery Chargers with 2 Pack Button Rechargeable Batteries (Charger + 2 Pack 312 Batteries)

Tried these and the first ones I got one would not charge at all, so sent them back and amazon replaced them with a second set and I had the same problem. I would not buy these again.

Excelente dispositivo y muy práctica la carga duración muy buena

This was one of the worst purchases I have ever made. I have older rechargeable hearing aids and haven’t been able to find the batteries anywhere so I thought I would try this product. It was the only one out there available for my hearing aids. It worked for a short period of time. Long enough that I couldn’t return it. A total waste of money. When the batteries were fully charged they still did not last the whole day. Now, 5 months later, they don’t work/charge at all. So sorry I purchased this.

A very good item to have. I read other reviews, so I decided to purchase this item. and take a chance on this product. There are not a lot battery chargers, like this to purchase. I have used this now for a few days, and "Wow", this is great. I had at least 10 packs of 312 batteries, and they are about half dead and do not last. Now, I can carry this charger with me, and they last about a day, at least 8 hours, and that is about all I need, then I just let them charge, and it does not take long to get charge (abouts 30 minutes or less). I also purchased the additional 4 batteries and 'Now I am all set. Thank you for suppling this product and I hope this company expands and make improvements and upgrades to this product. Thank you!

Do not last all day

IT looks good, but i don’t not like that that it takes the hearing aid batteries, a long time to fully charge.

Can confirm that it is a PITA to get charging. The description is accurate on that. Doesn't charge unless plugged in to power-source so it is not appropriate for charging on the go. I recommend that they fix the product of the issues they are aware of and add an internal re-chargeable battery so it is useful on the go. Otherwise it is exactly as described.

Ordered charger + 4 batteries. the batteries only last 3-4 hours after full 8 hr. charge. I had to carry ordinary batteries all the time because I didn't know when they would die. I want full refund.
