Yes, they are the same. PR41 is just the IEC designation, but commonly known at size 312.

I had the box and this I really dont know,, However I had these batteries since last march of 2013 and I am still using them and I will order again. Believe me you wont be disappointed in ordering these at all. They are well worth every penny I paid. Locally they go now for 10.00 dollars per card. In the box there are ten cards. Figured that out and they are so much better and long lasting....Hope this helps!!!

If you wear hearing aids and are asking in comparison to other brands do they last longer, no. I've tried name brand retail and also recently purchased through another on-line vendor (a subsidary of a lesser retail brand). I've found that all brands last about the same. I wear my HA's all day from early morning until I go to bed. I tracked it at one time and I believe batteries last about a week - 10 days for me. But this is the brand that came with them originally and the price is significantly cheaper than the store and even somewhat cheaper than the other on-line company.

I doubt it but at least they'll be clean and dry -- stick one in and try it --and be more careful in future

I've been using PowerOne 312 hearing aid batteries for 2 years now and consistantly get 5 or more days uses out of them. I wear my hearing aids about 12 hours a day and they are bluetooth connected to my cell phone.

Maybe there isn't one on the box, but the individual packages are dated. Mine (actually my husband's) are dated 10/16. they are made in Germany, so perhaps they list their dating a little differently.
