Watched a YouTube about making hearing aid batteries last longer, he put tape over the batteries when he removed them, I though that might leave a sticky residue.
So I decided to use the original covering to put over one of them when I took them out
Result was about 17 hrs. Difference.
I don’t wear them every day and not always all day. Don’t wear them in shop.
Your results may be different, mine were kirkland brand 312.
Daily use table date/hours in use.
14/5 15/2 16/7.5 17/10 18/0 19/12 20/0 21/5 22/5 23/3 25*/10.5 26/6.5 second failed
* the first battery failed.after 49.5 hours of use with no covering. The second failed at 66.5 hours.
Anyone else tried this?
