Cheat Sheet: 11-speed battery check

Updated May 4, 2025 by BetterShifting Terry

To check the 10/11-speed main battery charge, press any shift button for about 0.5 seconds. Personally, I prefer to press both buttons on the shifter, because that'll prevent the rear derailleur from shifting all the way up/down the cassette.
