Rayovac Extra Hearing Aid Batteries, Size 312 (80 Total Batteries)

I have used these batteries for several years with great success. Unfortunately, I have found a small number of batteries in my last purchase to be dead when I put them in my hearing aid aids.

Please understand that if you buying these, these batteries are the rejected battery packs from Quality Control. At approx. $.25 cents each battery ($2.00 a pack) you will get 1, maybe 2 batteries that have a charge. 7 out of 8 are dead on average. No charge, or very little charge. Not a deal at all in the long run, and it is aggravating to say the least to go through installing these in your hearing aid, one at a time wondering which one will work. Sometimes it is the first battery, (haha, happened once!) but usually is the 4 or fifth before finding the good one.
