I'm not sure why people say the battery life is short. I use my hearing aids for phone calls, listening to audio books and podcasts, and listening to movies pairing with my remote microphone. The batteries last a week or longer. Maybe they're not storing them properly or not allowing enough time to activate. These work better than Energizer or other top brands. They're priced right but the plastic packing is ridiculous to access. The cardboard packaging of the same MM type batteries is so much easier to open but come with 8 less for the same price will be my go-to batteries. This new plastic packaging is extremely difficult to open. Especially if your batteries die while driving or in a store/restaurant/movie theater/plane/anywhere else where good scissors aren't available. One basically has to purchase a good quality utility scissor to carry in a purse or a pockets to avoid not being able to hear. While the battery itself lasts a week for me, I'll go back to the cardboard packaging. Lazy irresponsible parenting is the reason for Reese's law. I'd like to give the packaging a -5 star rating.

Packages do not open easily.

Not a fan of the packaging

work very well last as long as other brands

Batteries great. Needle nose pliers to open the package, a hassle.

Batteries are fine. The packaging is really bad! Way to hard to get batteries out!!

Fitted well into my dad’s hearing aids. Good quality item.

Don’t last long. Extremely hard to open

Don't like the child proof package, to hard to open if you're old

Good product but they are harder to get out of the new packaging
