Kirkland Signature 1.45 Volt Mercury Free Premium Quality Hearing Aid Batteries, 312 (48-Pack)

Great hearing aid batteries with reasonable price. Would buy again.

Good batteries. Use a lot of them.

Very hard to access batteries from packaging, should by changed

The batteries are fine and the price is good, but the packaging is awful. It's described as being childproof, but it actually presents more danger to children because you're left with a lot of loose dead batteries that can't be disposed of in the trash. I finally put them in an empty childproof pill bottle and will take them to recycling center. Plus you need scissors to remove new ones, and they're still difficult to get out. I tuck a card of batteries in my purse in case one dies away from home, and I'd have to carry scissors as well with this inconvenient packaging.

Love the batteries. They are long lasting but HATE the new packaging! Will NOT purchase again. I will find something that is easier to open. I had to cut and cut and cut to get to the batteries. Now have loose batteries in a little box.

I used another brand 312 hearing aid batteries for several years and was happy with them. Then, in the last year or two their quality went very strongly downhill. I tried these Kirkland batteries and I find them to have very consistent life per battery with a lifetime at least as good as my old choice before they went downhill.I find the Kirkland batteries to be an excellent value in terms of battery life per dollar. And they are certainly frustration free - they don't die early, they all work as expected, none have been dead right out of the package.

Perfect batteries for Costco Hearing Aides.

Very good batteries, last 6 days which is great. Package arrived earlier than expected so I am pleased.
