Shimano said about a thousand miles depend on how much you use it, annoying thing about Di2 is that they don't sleep (unlike eTap).
About 60 hours is what I've found.
Do you have D-fly?
I definitely dont charge mine that often. Thats like 20 rides! I reckon I get more like 150 hours
Which makes me forgetfull. Which isnt helped by my Junction A being hidden.
