Oops, sorry, you are right, the year is only marked with the last digit, so it might also be 2017.

(Wew, time is running...)

BTW: the M48T02 is still fully active and not discontinued, but it is not easy to find the right category for it.

Without asking the manufacturer of the system which data code he used (it is on the tube labels of the components), you can only find out by estimating: the battery will last at least 10 years - 2007 is now (2021) 14 years ago.
