No date on these, I believe they are old.
There is no date on these, and I hoped for the best, being Panasonic. Half of what I got has less than 3 volts, I swapped out two due to device not working, then checked the rest. Sad thing is I already ordered another 10 pack. I think these are old, but since there is NO DATE, who knows?<br />  I also bought some Energizers, same battery, but they are dated! Good until 2026.
