Energizer EZ Turn & Lock Size 312
New Hearing aids batteries
I want to thank you! for your help in understanding the new type of battery ( zero mercury) after getting a new pack of batteries, followed your instructions on taking off the peal, letting them set for three minuets.
They work just fine, don't recall seeing that info on the pack we had.
Again thank you! Bob

Battery life 0-2 minutes
Purchased 312 eight pack at CVS Jan 2013 w/01/2014 "best before date". Two were dead immediately, remainder lasted < 3 min. Very disappointed in product.

This product did not perform well
My husband bought a large number of Engergizer batteries size 312 for his hearing aids within the expiration date. He has had very poor results. These batteries only last about 3 days compared to others even store brands lasting a week or more.

I cannot believe you replaced the EZ changer with this piece of cardboard. Why, Why, Why? There is no comparison to using your previous EZ changer with this replacement. You could have used longer lasting batteries in the former EZ changer just as well.

Lousy battery life and durability
I use my hearing aids every day up to 16-20 hours per day. Then I expect the battery to keep at least 4-5 days, not less than 24 hours!
