Yes, they are the same. PR41 is just the IEC designation, but commonly known at size 312.
When used in hearing aids, 2 batteries per week, shelf life has never been an issue. Sixty batteries work out to about a six month supply
how long do they last ? Aug 20, 2013
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.
What is the expiration date of the package? May 28, 2014
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!!!
looking for powerone batteries with MERCURY not zinc. i cant seem to get a straight anwer. please HELP 14 days ago
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 recently ran a few unused ones through a wash & dry cycle. Do you think they are still serviceable? Jun 27, 2014
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.
They last about 5 days............
If the background color is brown then yes.
