good

These last pretty good. Had no problems using these.

I get about a week and a half on one battery in my high powered hearing aid.

Good Batteries for my grandpa's sound amplifiers

I had upgraded my hearing aids, in which the last set was using size 13 batteries, and they lasted about a week. I have since upgraded to a later set of Phonak H/A's (Naida P70-UP), and these batteries are lasting up to 3 weeks. I stream a lot via my H/A's, which uses one of the 2 aids for the streaming, and that cuts that aid down to 2 weeks.Not sure what other 675 batteries do, but I've read up on these a little, happy with them, and will most likely stick with them.

As a user of hearing aids for about 5 years I have used two different types of hearing aids, both analog and digital. The first set of aids were analog and they used a button battery type 13. My current digital aids now have Bluetooth and use these P625 batteries. Incredible improvement in the length of useful time these P625/R44 are able to provide. My experience with these German made “Power One” has been great. There has been no leaking or inoperable batteries and as previously mentioned the energy provided is significantly longer lasting. Uncertain as to comparable energy consumption of the analog to digital hearing aid devices. Great product at a great price. Highly recommended.

They’re a good hearing aid battery, lasts a decent amount of time.
