ZeniPowerZinc-Air Hearing Aid Battery Size 312 (60 Batteries)

These batteries are so much cheaper than in the stores. So convenient that I can send them right to the care home where my 99 year old Aunt is. On her 90th Birthday I told her I would buy her hearing aid batteries for the rest of her life. I am thankful she is living so long at this price they are not going to break me.

These don’t even last 5 days, using them 7 hours a day. A few have not even lasted a day before I get the low battery alert. I won’t buy this brand again.

These batteries are awesome. Some of the other brands I have purchased only lasted 2 to 2 1/2 days and I'm getting 5 days out of these Zenipower batteries. I wasn't able to afford rechargeable hearing aids and I can't tell you the number of batteries of other brands I had used. When I got the Zenipower batteries I was amazed at how they lasted twice as long as the other brand. I am very happy with these and I will continue to buy them. Thank you, Zenipower

These are great batteries. Mine last almost a week! I did have to mark them down one star because they are extremely difficult to remove from the packaging. Am wrecking my kitchen shears opening the plastic.

I purchased these last year (11/2011) and they lasted just as long as the ones I get from Costco (still love Costco!). Since these arrive in the mail I decided to wait until cooler weather before ordering again (in the summer it is 115 here in AZ!). This time I am purchasing the 120 pack. That should get me through a whole year. The 120 pack is also discounted as compared to purchasing two 60 packs. By the way, the batteries typically have a 3 year shelf life so you don't have to worry about them expiring before you use them.

The batteries are fine, but the packaging is very difficult to open. I wound up cutting the tabs on the entire order and transferring the batteries to a container that was easy to open. I should have read the description more carefully because it mentioned the child proof feature, but I was not anticipating how difficult this would be. The plastic is very hard to cut and having to cut each tab is a real hassle. I can't imagine carrying these with me and trying to change them in a public place. These batteries may work for someone with a very young child, and they are afraid the child will swallow a battery, but for everyone else they are an unnecessary hassle.

Very difficult to open

I have been using these inexpensive batteries for some time now and find them quite adequate for my needs. They last as long as more expensive batteries which was my main concern when buying them. Now like any battery of any price made here in the USA or abroad some will have a shorter run time and maybe even one will not work altogether. That's the price of mass produced products. But if you insist on paying more for batteries to be happy then do it but for me, I'll pay a lot less for my batteries.
