Energizer EZ Turn & Lock Size 312
No more than two days before having to replace?
Extremely disappointed in these batteries. Never got more than 3 days usage before the beeps would start, indicating that the power life was coming to an end. Typically I'm able to get a week out of most hearing aid batteries.

I purchased this battery pack of #312 for my hearing aide in June of 2013. The first battery lasted a little over a week, 2nd, 3rd and 4th lasted less then one day. 5th battery last one full day. I now have 6th battery in and we shall see how long this one lasts. This has been the worst set of batteries I have ever had. What seems to be the problem? Old Batteries?

I had never used Energizer hearing aid batteries and saw a great deal at Sams Club so I purchased a pack. What a mistake! My hearing aid keep shutting off and turning back on for no apparent reason. After paying for an appointment at my audiologist they tell me that it is the Energizer batteries. They are just the tiniest bit smaller than the other brands I have used and loose contact. Not a deal after all when I am stuck with batteries that do not work.

Bad package design
The EZ Turn & Lock is thicker than the flat-pack, and does not fit in my wallet as well. The flat 16-pk is a better, more convenient package design.

Good Value, but its a gamble
I have been using Hearing Aids my whole life, looking for the best value for performance. Unfortunately, I had a negative experience with this type of battery. However, I did get a great value for these hearing aid batteries, (being a college student, cheap is always good!); but in the pack, I did encounter one major problem, I had a dead battery in the pack.
That wasn't the only problem I encountered; I also had difficulty with the battery life. Some of them would last me a week and a couple of days, which is better than most brands, but then some would last 4-5 days. So I would have one hearing aid battery working, when I have to replace the other. As any hearing aid owner, its a pet peeve to us when one of the batteries dies and the other doesn't die within the next 3 hours.

do not last for one day
Could not find one good thing
One shut down in just 5 min
others with in same day shut down
some did go for two - three days
what a hassle to carry 312 aroud just to keep going...
I bought 24 pack lasted only 13 days

These batteries do not last!
I purchase these in a pinch when I cannot get to Costco to buy there batteries. The last 2 times I have purchased I have had two dead batteries in the pack. Today I bought some from the local grocery store and they are dated for 04/2014, well I installed two batteries, one for each ear and the left side died within 5 minutes. This is ridiculous. Spend $9 for 8 batteries and they do not work. I will never buy again!

"Lasts 4 hours longer" is a misleading statement when a battery fails after a day.
