How to Replace SRAM eTap AXS Shifter Batteries

Clocks are set back and it’s time to replace your eTap AXS shifter battery. Trust me, you do not want to have it die on a hilly ride. This has been learned from experience.

SRAM AXS shifters use a common CR2032 battery secured by a simple battery cover, and it will last nearly two years of normal use. Let’s walk through checking the status and replacing the battery in a few easy steps. 

The LED on AXS shifter paddles and derailleurs can tell you a lot while pairing components together, updating the firmware with the SRAM AXS Mobile App, and checking the battery status. 

The simplest way is to perform a shift and compare the LED light with the battery status chart to determine the approximate amount of life left in your shifter battery.
