Description
Rayovac Extra Advanced Hearing Aid Battery 312 (PR41)
Rayovac is a very popular brand of hearing aid batteries.
Sold in packs of 6, these long life hearing aid batteries are compatible with all hearing aid brands without exception and are recommended by our partner audiologists.
Function:
A pack contains six 312 size hearing aid batteries. Zinc-air batteries use oxygen as fuel to provide as much energy as possible for your hearing aids. You can use these batteries in all hearing aids.
Zinc cells use oxygen as fuel to provide as much energy as possible to your hearing aids.
You can use these batteries in all hearing aids.
Batteries are now 0% mercury (mercury-free batteries):
Before 2015, hearing aid batteries were the last batteries in Europe to contain mercury in their components.
In October 2015, hearing aid batteries became more environmentally friendly (and recyclable).
They've caught up to standard batteries and are now mercury-free.
Distributors are prohibited by law from importing mercury-containing batteries into Europe.
Regarding changes:
The shift to mercury-free battery manufacturing will require some changes and investments by manufacturers to comply with European legislation.
Manufacturers like Rayovac and Powerone made several versions of 0% mercury batteries before getting the solid, reliable products we sell today. 0% mercury batteries have been the norm since 2016 and manage to deliver the same quality as conventional batteries.
The change has been a huge win for battery manufacturers, who are now producing batteries that are greener, mercury-free and perform at comparable levels. So the law works by improving products and making them recyclable.
Features:
・Color code: Brown Type 312 (PR41)
・A pack of 10 packs of 6 batteries
・1.45 Volts Zinc Air
・Battery shelf life: up to 4 years at most
・Capacity: 180mAh
・Size: about 3.6×7.9mm (height×diameter)
・Mercury-free
・Suitable for all electronic and analog equipment
how to use:
Why did Audilo and my audiologist advise me to wait 1 minute before inserting the batteries into my hearing aids?
Zinc Air Batteries use complex technology related to the chemical reaction between zinc and elements in the air.
This is why the surface of the battery has holes (to allow air to circulate and activate the battery).
But what happens when the label is removed?
For the first few seconds the battery's voltage rises dramatically when it comes into contact with air, then after about 10 seconds it drops again to almost 0 (this explains why hearing aids detect if you also plug in the battery to some batteries are depleted quickly). After about 30 seconds, the battery voltage will rise again and stabilize for maximum usage time. We recommend that you wait 1 minute before removing the sticker just to be sure.
Rayovac Extra Type 312 Hearing Aid Batteries (PR41)
Rayovac is a highly popular hearing aid battery brand.
These long-life hearing aid batteries, sold as a pack of 6 batteries, are compatible with all hearing aid brands, no exceptions, and are recommended by our partner audiologists.
Functions:
This pack of ten packets contains 6 size 312 hearing aid batteries.
Zinc air batteries use oxygen as fuel to provide your hearing aid with as much energy as possible.
You can use these batteries in all hearing aids.
The batteries are now 0% mercury:

hey have caught up with standard batteries and are now mercury-free.
The law prohibits distributors from importing batteries containing mercury into Europe.
About the changes:
The switch to mercury-free battery manufacturing has required a number of changes and investments from manufacturers in order to adapt to European legislation.
Manufacturers such as Rayovac and Powerone made several versions of 0% mercury batteries before achieving the stable, reliable product we sell today. Since 2016, 0% mercury batteries have been the norm and have managed to offer the same quality as traditional batteries.
The change has been a great success for battery manufacturers, who now make more environmentally friendly, mercury-free batteries with equivalent performance. The law has therefore fulfilled its role by improving products while making them recyclable.

・Dimensions: 3.6 mm x 7.9 mm (H x Diam.)
・Mercury-free

How to use:
Why do Audilo and my audiologist advise me to wait 1 minute before inserting my battery into my hearing aid?
Zinc air batteries use complex technology linked to a chemical reaction between zinc and the elements in the air. This is why there are holes on the face of the battery (to allow the air to circulate and activate the battery).
But what happens when the tab is removed?
During the first seconds, the battery's voltage increases sharply when it comes into contact with the air, then after around 10 seconds, it falls again almost to 0 (which explains why some batteries are detected as depleted by your hearing aid if you insert them to soon). After around 30 seconds, the battery voltage will increase again and stabilize for maximum usage time. We advise you to wait 1 minute before removing the tab, just to be sure.
There is no one battery brand that is more reliable than the others, or that will last twice as long. You may, however, notice some variations depending on your hearing aid, but they won't be significant. If one battery brand was better than another, we would tell you.
Users are sometimes more attached to a certain hearing aid battery brand out of habit, rather than because of their capacity or battery life.
