my current batteries are rayovac 312A. Will the batteries that are labeled 312 going to fit? What does the A mean?

Don't know what the "A" means but I now use the German batteries also sold on Amazon. I've been very satisfied with them and the price is right. the Rayovac batteries are okay also but the German batteries seem to be better for the price.

I have no idea if 312A is the same as Duracell 312' we like the Duracell for ease of installation with the longer tab on the battery

312 determines the size: 312 or 312A have exactly the same size and are both mercury-free zinc-air batteries of the same output voltage and capacity. Different manufacturers put letters before or after the "312" to identify their own product numbers.

Guy: I am sorry, but I am unable to answer your question because I had already discarded the packaging that might have provided this information. I do really like these Rayovac batteries for my hearing aids. By far they seem to last the longest for me and my use and the convenience of the quantity and price. I will be ordering again. Have a great week.

I am not certain. I matched the numbers on my battery with the one I ordered.

Yes, 312 batteries are the size for the hearing aids that we have. It works great to test them.

Larry I am not familiar with the battery in question, but all you need to be concerned with is the size of the battery you are replacing will a different one fit, next is the connector type on top if the are the same or you can easily re-adapted the connection, next and most important is the right voltage such as 6 volt or 12 volt,next is the AH stands for Amp Hours the more the better the more the bigger the battery, so I hope this has helped you, don't worry about matching brand.

I don't use the #312 battery now but the #10 as I have changed my hearing aid. However I have checked the surface where you place the battery and it is big enough to take the #312 battery. I hope this helps?

The back of the package reads: IM312A-16ZM 1.45V Replaces all Size 312 Zinc Air Batteries. Hope this helps.

Sorry I can't help you there. If you do find that it will fit all I can say is this, If you work inside, this unit works great and is accurate as hell. I'm still running on original batteries and I use it a lot. Comes with second set. If you work outside, don't bother.

You want me to be honest, I don't know. I just bought the battery that said worked in the radio I had, as a spare. I wouldn't want to be wrong and just say that it would be the right one, and it was not the same thing. Fharm50

I've not heard of 13A or P13. I would ask where I purchased my hearing aids, about those type batteries. I do know that 312 are smaller than 13. Sorry I can't be more help.

I have no idea what that battery is . Did it come from a Chamberline Unit? Battery 4228 will fit all units.

We purchased these and they do say 312A. The batteries work just fine and we are pleased with them and will order them again.

there is no difference between a 312 battery and a 312a. It is a manufacturers designation only, The batteries are the same. Voltage is shown either as 1.4V or 1.45V. Both will work perfectly in hearing aids designed for size 312 batteries. One thing all battery manufacturers agree on is that you should let a new battery stand in the air for about 60 seconds before closing the lid and using the hearing device. They are all "Zinc-Air" and must be activated before use.
