What is the shelf life on the power One zinc p312?

Manufacture date is needed on every -front of package- mandatory hearing aid battery mfg i have found dates Oct 2018 still selling here on amazon, today 1/31/2021 .. this is unacceptable we all want to purchase new batteries for best shelf life and overall wearer - performance.

The voltage on these is 1.45v. I've had good luck with these and are certainly less expensive than over the counter batteries.

will these fit HEARusa hearing aids?

Based on the information found for the HEARusa hearing aids, they take size 312. Therefore these batteries will work.

These are size 13 batteries. We do carry size 312A batteries if searched using the following product identifier: B00SJPHZCO.

Batteries were fine but you need major-league scissors to access them. Hearing aid are usually for those that are beyond toddler years so childproof loses its meaning here. Yes, I have a grandchild but the access issue offsets the benefit by far
