So far, I think these batteries are going to be great. Sure a lot cheaper than buying at the store. They seem to last as long as the Duracell's I have been using. Actually, I've had a lot of duds in all brands bought locally. I live in the desert & I think what's happening is the truck parks somewhere for lunch maybe & things inside gets hot. These batteries can't take much heat without unsealing the little sticker tab. Once that happens, the battery starts discharging just like it was in a hearing aid. If I start running into bad batteries, I'll up-date this review but, for now, I think they're great. Also, they come with a handy little key-chain plastic thing with a snap close lid that will hold a pair of spare batteries. (with the tabs still on) Update 11/6/17: Just about finished my 1st box. Not one dud in the whole box. Consistent performers. Very pleased. Just ordered another box. 2nd update 4/20/18: Still like 'em. I've modified the little keychain spare batt. holder .I've glued a tiny magnet into the slide out handle & it works perfect to insert a fresh batt. into the hearing aid. I was always kind of fumble fingered trying to handle these tiny batteries. Now with my "magnetic holder", it's much easier. Hearclear ought to build a magnet into their keychain. It really works!

Imagine your hearing aids beeping that its time for a new set of batteries. Could be in your own home, or out and about in the world. This brand requires that you must have a pair of scissors or blade with you in addition to the individual packages to be able to extract a couple of fresh batteries. Imagine having to cut the package just to get the products out to be able to use. Each time you use your box cutter or office scissors, you will no doubt find small pieces of sharp package in the area, as after you cut and replace the batteries, its a good bet that you miss some of the plastic. Really fun when you get up and crunch on a sharp piece of plastic. Silly that this brand does not use a rotating package with a door that is easily opened in the plastic package, so each battery drops out into your hand or onto your bed or desk, etc. Easy as pie, and super simple. Would never get this brand if the cost were free, and happy to purchase the few brands that have the sensible packaging that you can work with your eyes closed. Stay far, far away from this brand unless you enjoy being tortured. I threw away a few dozen of these packages, and was so delighted to get rid of them. Terrible.

Item was easy to locate, great price. Will order again. Thanks for the quick service.

They claim they're long lasting blah blah blah .... Mine were delivered on Feb 17 .... Here we are on Feb 20 and I have already used 4 batteries and my hearing aid just started beeping to alert me of a low battery. I take the batteries out at night while I sleep. . . I typically have my hearing aid in front about 7am to 10 or 11 pm. I have had to change the batteries every day, and in 2 cases twice in a day ... Hense the 5 batteries in THREE DAYS!!! What a joke! Thank god I bought 60 batteries to power my trash bag. Batteries should last for about 70 hours from what I've read ... This is my first hearing aid, I use it for treatment of tinittus I'm not hard of hearing so it's not like the device is turned up super high either .... I use it to enhance frequencies 4k to 6kh .... Normal batteries should last days if not a week maybe slightly longer .... In any case more than a few hours smh .... Yeah the cost is cheap ... But that's exactly what the product is also cheap AF JUNK..... Thanks for stealing my $$ .... You get about 4 batteries worth of life in a package of 60 ... Yay

Batteries work for the most part although I have had three of them not work at all straight out of the package. On addition, the packaging is extremely difficult to open and not convenient if you are out and about and do not have scissors handy, as they require scissors to open. Will not buy again.

I've ordered hearing aid batteries here a couple of times but on my recent purchase, it was the first one that has the child-proof packaging. The Con - While it's a great idea to develop packaging to safeguard the small batteries from small children, they're a bit of a hassle to get a battery out (have to take scissors or wire cutters to cut open one section) which is why I'm giving this four stars instead of five. The pros of this is the longevity of the battery - giving me 2-3 more days of power compared to the ones that I get from my hearing aid dispenser. The second pro is the ease of being able to get the size 675 battery here. In my area, only one grocery store in another city 20 miles away carries them. No store in my city carries the 675 size battery and they're getting harder to find.

These batteries work if you can get them out of the packaging. It is almost impossible to get them out since they created child restistent packaging. Especially if you have arthritic hands like I do. You have to cut them out. It takes me a half hour to do it. Very frustrating experience. Do Not buy them unless you have the time and patience to go through all that .

Batteries were fine. No problems.
