It seems that this is the number 310 or October 2013, but who knows.
I wonder what factory.
TL;DR: 73 % of Bosch serials start with a "year-week" trio; "the first digit is the year, the next two the month" [Elektroda, telwisalfa, post #10439337] Use digits 4-6 of the long top-cover code to decode, e.g. 310 = Oct 2013.
Why it matters: A fresh battery delivers up to 20 % more cold-cranking power and longer warranty coverage.
