I thought there was something wrong with my hearing aid and spent a lot of money wasted on Rayovac 312 batteries. I threw out battery after battery and yes, I waited the minute to insert into my hearing aid after removing the tab. I went to a wedding event this past weekend and was so frustrated and gave up on my hearing aid. When I returned home, I charged my rechargeable battery and voila my hearing aid works just fine. I would like a refund for the three eight packages I bought.
After having hearing aids for over 10 years, i bought my first pack of Rayovac batteries. Out of the first 4 batteries, I had 2 go dead after 2 days. Normally my hearing aids give a warning tone when the batteries get low. NO warning, just dead. I have never had this problem with other brands. I used 4 out of a pack of 24. use by May 2022, LUUPF 0028.
