SRAM AXS Battery

ABOUT AXS BATTERIES

If your bike is AXS-equipped, you have at least one rechargeable SRAM AXS battery. Capable of powering a whole host of AXS components, these tiny power units are interchangeable between parts on your bike, easily swappable during a ride, and fully rechargeable in an hour or less. The same battery is compatible with front and rear eTap AXS derailleurs, Eagle AXS derailleurs, Reverb AXS seatposts, and Flight Attendant suspension.

"Do I need a spare?"

Think about spare batteries like you think about ride snacks. Do you need a bag of gummy bears on every ride? No. Does it save the day when you feel the bonk coming? You bet!

Your AXS batteries bonking mid-ride is unlikely, as they will last hours upon ride hours depending on component:

• Road derailleurs: 60 hours
• MTB derailleurs: 25 hours
• Dropper posts: 60 hours
• Suspension: 20-35 hours

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.
