SRAM AXS Battery

The SRAM AXS Battery is the compact, high-efficiency power source behind SRAM’s wireless AXS ecosystem. Designed for fast swaps, universal compatibility, and reliable long-lasting performance, this battery keeps your drivetrain operating with zero cables and minimal downtime.

Key Features & Benefits

Universal AXS Compatibility
One battery powers all major AXS components, including front and rear derailleurs, Eagle AXS systems, and Reverb AXS seatposts, making it a fully interchangeable, system-wide solution. 

Tool-Free, On-the-Fly Swapping
Quick-release design allows riders to swap batteries in seconds, critical for mid-ride contingencies or race scenarios where uptime matters. 

Fast Recharge Cycle
Fully recharges in approximately one hour, with meaningful charge achievable in as little as 15 minutes, ideal for tight pre-ride prep windows. 

Lightweight, Compact Design
At roughly 24 grams, the battery is negligible in weight yet high in output, making it easy to carry a spare without penalty.

Reliable Ride Duration
Delivers extended ride time per charge (commonly hundreds of miles depending on usage), minimizing charging frequency and reducing drivetrain interruptions.

AXS App + LED Monitoring
Battery status is easily tracked via onboard LED indicators or the SRAM AXS app, providing real-time visibility into charge levels.
