What is the SRAM AXS Battery?

The SRAM AXS Battery is the standard rechargeable battery that powers all AXS wireless components: Eagle AXS derailleurs, eTap AXS road derailleurs, Reverb AXS dropper posts, and AXS Pod Controllers. It snaps directly into the derailleur or component, charges via the AXS Battery Charger, and provides enough runtime to handle well over a month of typical riding between charges. The system goes into power-save mode when the bike is stationary to extend battery life. Battery level is visible at a glance via LED indicator on the component, and the AXS app provides exact battery status for all paired components.

Keep a spare AXS battery on hand for long tours or race weekends where charging may not be convenient. Compatible with all SRAM AXS components that use the standard AXS battery form factor.
