Just got these Powermax 312 hearing aid batteries and wanted to share my thoughts. First off, the battery life is impressive! Mine lasted a full week with daily use of 13-16 hours. That's way better than some other brands I've tried.

BUT...the packaging is a disaster. I get that it's childproof now (thanks Reese's Law), but come on! I had to use scissors just to get one battery out. Not exactly convenient when you're out and about. Ended up cutting them all out at once and storing in an old pill bottle - not ideal.

The batteries themselves work great though. Clear sound throughout their lifespan, no weird power drops. And at this price for 60 count, it's a good deal if you can handle the packaging hassle.

Pro tip: If you have arthritis or weak hands, maybe look elsewhere or be prepared for a serious struggle session every time you need a new battery!
