Description
The SRAM eTap Battery is the rechargeable power source for SRAM wireless electronic derailleur systems. It provides the electrical energy needed to operate eTap derailleurs and communicates with the wireless shifting network to deliver consistent, reliable shifts.
This is an essential service item rather than an accessory for aesthetics. Compared to basic disposable setups, the eTap battery is designed for long life, easy removal, and straightforward charging — making it practical for riders who want dependable electronic shifting without fuss.
