Any date code available on these?
The “Use by” date is noted in the features. Hope that helps.
Most new batteries have a 10 year shelf life which would mean these were likely produced in 2009…yuck
We’ve talked to our vendor about this.
Not all batteries have a 10 year shelf life. Many do but not all.
What you want to look at is the expiration date. These are best used by 2019-2020, depending on the battery.
FWIW, these batteries were manufactured in 2013.
