SRAM eTap and eTap AXS Battery

SRAM eTap and eTap AXS Battery is the compact rechargeable power source used across compatible SRAM wireless electronic components. It is designed for SRAM eTap and AXS front derailleurs, rear derailleurs, Eagle AXS mountain-bike derailleurs, and compatible RockShox Reverb AXS seatposts. The interchangeable design allows a rider to move one charged battery between supported components or carry a spare for travel, racing, and long-distance events.

This genuine SRAM battery installs without tools and locks securely into the component’s battery mount. Its small size makes it easy to keep a backup in a saddle bag, gear case, or shop service kit. A fully charged spare can prevent a low-battery warning from ending a ride and gives mechanics a convenient way to test an AXS component during diagnosis. Charging requires a compatible SRAM eTap or AXS battery charger, sold separately unless otherwise noted.

Before ordering, confirm that the bicycle uses a removable SRAM eTap or AXS component battery. This battery is not a replacement for coin-cell batteries used inside AXS shift controls, and it is not intended for systems from Shimano, Campagnolo, Bosch, or other manufacturers. Inspect the contacts and locking tabs before installation, keep them clean and dry, and avoid storing the battery fully discharged for extended periods.

Each package contains one SRAM rechargeable component battery. Select this replacement for dependable compatibility, a convenient backup, or restoration of power to a supported electronic drivetrain or seatpost.

It is also a useful service-counter replacement for keeping customer repairs moving efficiently.
