Thanks
Yes, 2010 is the manufacturing date. This would fit to the expiration date of 2025.
Bought them at eBay Austria.
So it seems they are original and were only available outside the USA for a short time.
The funny thing is, that they accept recharging. I charged both empty cells with 100mA till they had 1.9V and could get another 1400mAh from both cells at 1A.
This does not work with any other lithium primary I know, so they must have some different chemistry.
I did this just out of curiosity and in the garage to be safe.
