Winter is here and now is a good time to replace your eTap AXS shifter batteries. 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 but we’ve found it a good practice to replace yearly. Let’s walk through checking the status and replacing the battery in a few easy steps.
If you don’t have CR2032 batteries already, chances are Amazon can have them to you tomorrow or the next day if you are a prime member. I found this the best option, as I never remember them when I am at the store.
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.
Watch this SRAM Tech video to see the full process of replacing an eTap AXS shifter battery. All you need for hydraulic brake systems are a coin to open the cover and a new battery.
