Sorry I can't be of more assistance to you, I bought the 312 for my daughters Hearing Aids which works great but never ones with A on them. Why don't you try enquiring from the sellers of this product.

I have used 312 for 5 years now with my hearing aids as this was the brand and # that was given to me with my new hearing aids...I've always found them satisfactory.

It will test #312 batteries, but it appears to be a "no load" test. I have tested hearing aid batteries that tested fine one day and didn't work the next. I have pretty much stop using this device.

The number 312 is not on the barrel at all. The overall length is 4.5" this refill has been a true to original replacement.

There are no difference between CR123 and CR123a batteries. They have the same size, only their names are different because CR123A is a most common names. Stay away from Ultralast.

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 312a appears to be a slightly higher voltage than the 312 hearing aid battery. It certainly will not damage any device that originally specified 312 size batteries as it has the exact same dimensions. The 312a gives far fewer false signals to indicate need to replace. Frederic Todd

Yes the same in essence. the biggest things your going to look for in these batteries is the dimensions. Obviously voltage (12v) and capacity ( 18-19 amp hour) is a factor but you can play with the Ah's +- a little. But Can't use it if it doesn't fit in the battery locationFor in these types of batteries

181-02 has Two slim pack battery's And 181-01 has fat pack battery's. fat packs (2.6 ah 3ah) it will say in description most common is 3ah and they have a lot longer run time than slim pack (1.3ah& 1.5ah)

Should be since the numbers 312 mean a common size. The power one P13 is the same as any other 13 such as Duracell or Energizer.

I'm not familiar with the 312, but these are the common size # 13 purchased most anywhere batteries are sold. They are made in Germany,package says 1.45V Zinc Air. They are definetly long lasting and I'm happy with them.

I doubt it. I'm guessing the 312 is the size battery that you need. That is one of the most common sizes for hearing aids.

Please note that all hearing aid batteries are Zinc Air. What you are probably referring to is batteries with Mercury, which would be the Power One Size 312 hearing aid batteries. Any of the ones listed as Mercury Free would not contain Mercury, and most likely, not be what you are looking for.

I am currently using the 312a batteries. I have used both in my hearing aids and have not noticed any problems. HOWEVER, check with your hearing aid manufacturer to be on the safe side.

I believe they are the same between 377 and 377A (LR626). You can query on the web for their references or look up 377 battery on Amazon and see the product description.

Most of the Sony CR2032 batteries are CR2032. Yours are CR2032A. Can you tell me what the difference between the CR2032 & the CR2032A is ? Thank You

These work for hearing aids that require 312. 312A and 312 are compatable for 312 hearing aids. These batteries work great.
