SRAM AXS BATTERIES, CHARGERS & Bundles

For AXS, Flight Attendant, and eTap components

sram axs - the heart of it all

If your bike runs AXS, you’re already relying on the same rechargeable SRAM AXS battery that powers everything from derailleurs to seatposts. One battery works across the whole ecosystem: Eagle AXS, road AXS derailleurs, Reverb AXS, and Flight Attendant. They swap fast, recharge in about an hour, and every rider ends up wanting more than one.

Stock up and save with our new AXS bundles. Whether you just need a backup battery, a full garage setup with a 4-port charger, or a full travel kit, you’ll find bundle options on each product page that beat buying everything separately.

  • Do I need a spare?

    For such a small package, an AXS battery packs a big punch in terms of power, so why not have an extra on hand in case of emergency. Toss one in your tool roll, bar bag, or pocket. You'll hardly notice it's there...it's only 24 grams after all.

  • What about washing

    Your AXS system is completely waterproof, making washing your bike easy. Remove your batteries, reinstall those red things, and wash away without worry.

  • Do I need to stick with the SRAM brand?

    While inexpensive generic options are tempting online, they are not worth the risk. Genuine SRAM parts are designed and tested with a priority on safety and optimal performance.
