## Questions & Answers

**Q: In the description it says to expose to air for 1 minute to activate. Is this really necessary?**
A: According to my audiologist, regulations now forbid the use of mercury in hearing aid batteries, so the modern ones run on different electro-chemical principles than batteries did formerly.  If you look closely, you'll see tiny holes in the back of the battery that allow air to enter the battery once the tab is removed.  This step, apparently, is necessary to give the battery a little head start in its operation.  Again, my audiologist tells me that it's her experience that a 10-minute wait is preferable to a 2-3 minute wait in order to get maximum life out of a battery.  My wife and I have been observing the 10-minute practice and find that the batteries last a little more than a week using them up to about 12 hours per day.

**Q: How many days should these last if you take them out at night. What are the signals the battery needs replaced?**
A: How long they last is determined by the hearing aids and how long they are worn. I love these batteries because I usually get ten days from each battery. I was getting five to seven days from other brands. Rayovac I have found last the longest for me. I wear my hearing aids for up to eighteen hours some days.

**Q: Is it zinc-air?**
A: I think so.  I do not see anywhere on the packaging where it says it is zinc-air, but it does say it replaces all size 312 zinc-air batteries.  Each battery also has a sticky tab over it, and they are mercury-free.

**Q: What is the difference between the proline advanced rayovac and these extra advanced? other than the marketing guy out for drinks on friday.**
A: I have used the Rayovac Extra Advanced and they last longer than a brand I was using before. I get about 4 days of power for my hearing aids. I see that the Proline Advanced are packaged with (40) batteries while the Extra Advanced are packaged with (60) batteries while the Proline Advanced priced higher than the Extra Advanced.

## Customer Reviews

### ⭐⭐⭐⭐⭐ They are great batteries,they last a long time and I love the price. 👍🏻
*by P***O on July 7, 2025*

I love Thease batteries because they last a long time and they are very easy to remove from the pack just by turning the plastic wheel and they come out the back without any problem. And they will not work until you remove the little tab so the surrounding air activates them.👍🏻 and I love this price.👍🏻

### ⭐⭐⭐⭐⭐ Senior Accessible Hearing Aid Batteries
*by A***R on September 2, 2025*

These came in packaging seniors can open. As best I can tell all of these zinc air batteries are non toxic, yet CPSC requires them to be in senior proof packaging. (Please don’t tell them!)

### ⭐⭐⭐⭐⭐ Last box not good.
*by A***R on July 25, 2023*

Revised: Rayovac responded promptly. Asked for pics of packages with expiration dates and other relevant info. Received a full refund check for entire purchase. Great USA Company! I ordered another 80 pack and just got 6 full days from the 1st pair of batteries. All good! Just got a bad batch and Rayovac made it right! Have purchased multiple times in recent years. Quality has always been great. Rarely got a dud but the box purchased in April ‘23 is proving to be a different story. At first a couple were “short lived” and now steadily experiencing more bad ones. Just had 6 in a row that were dead or only lasted 30 seconds to a couple hours. Contacted Ray-O-Vac customer supportvia email so we’ll see what happens. Used Duracell for decades but switched to Ray-O-Vac a couple years ago as they are made in USA.
