Date of manufacture, according imprint "15/08/2013 (T)", sold 12.12.2014 - which I think is a battery as too old and not "new" (the industry service tomshardware recommends batteries> 6 months to return). In the second experiment, the battery could then load, the service life is however expectable already restricted. This does not correspond to my expectations. But he is original, so the shelf life is likely to be even longer than typical batteries of alternative manufacturers according to my experience in this case.
