These batteries look the same as the size 312. Are they the same?

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.

Sorry Terry, I've used them for some time, definately NOT the same. FYI, Amazon has probably the best quantity pricing on #13's AND you can usually get free freight. Good Luck!Jim

It will be the same battery, for some reason some manufacturers will have a couple of different item numbers for the same battery.

They are the same. I compared the original with the replacement and found no difference.

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.

Really don't know about fit. I will tell you the batteries we got from here were likely new old stock. Their performance degraded quickly and soon we were at about the same performance we had before replacement.

Yes they are EXACTLY the same size as a normal AA battery. I COULD NOT USE THEM as the battery I needed was shorter in length. (Part numbers were identical).

Hi Mike, I just received similar batteries from this vendor and I am 100% satisfied with the quality and performance of the products. After receiving them, I oredered two more for a 12 v Makita also. They appear to be a perfectly acceptable replacement to the originals.Buy with confidence, I did and don't regret it.

My numbers are different than yours. I think those are lot numbers. The picture there looks identical to mine. It's the size 312 that matters. I think they are the same. And they last 7-8 days for me.

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

I have been using 312 batteries for almost four years and they were all 1.45v. I'm sure in the description it was just and omission of a 5.

I Googled your question and it said it was the same battery. (interchangeablel)

If the batteries are similar to the #13 (which I use) then the tester should work with the #312.
