What Our Gearhead® Experts Are Saying:

"This battery is my security blanket for every AXS ride. Swaps are quick, and I love knowing I have a backup with just one small part. Whether it’s a century or a stage race, it’s always in my kit."

Engineered for seamless power on SRAM’s wireless AXS drivetrains, the eTap Battery makes sure your shifting remains crisp from start to final mile. Compatible with both front and rear derailleurs, it takes seconds to install or swap, no tools needed. Each charge yields roughly 600 miles, supported by a clear LED status readout so you always know when to top off. Lightweight and travel-friendly, it’s easy to pack two for epic rides, gravel races, or for peace of mind during overseas bike trips. Paired with the AXS charger (sold separately), one small battery delivers maximum reliability for every electronic SRAM build.
