SRAM AXS eTap Batteries

The SRAM AXS eTap Batteries are the universal, high-output power source that drives SRAM’s entire wireless electronic ecosystem. Engineered to deliver uncompromised shifting precision under the most demanding riding conditions, this compact lithium-ion polymer battery pack keeps your electronic components responsive across road, gravel, and mountain bike disciplines. Its tool-free, snap-in design allows for effortless removal and replacement in seconds, making it an essential component for your drivetrain and the perfect backup power unit to keep in your saddlebag for long-distance bike adventures.

Key Advantages

• Universal Interchangeability: A single, standardised battery profile powers every component across the AXS system. This allows you to seamlessly swap the same battery back and forth between front derailleurs, rear derailleurs, and dropper posts in a pinch.

• Rapid Charging Recovery: Fully charges from dead to 100% capacity in 60 minutes or less when connected to a standard SRAM USB-powered charging cradle, keeping downtime between rides to an absolute minimum.

• Ultra-Lightweight Profile: Weighing a mere 24 grams, it provides exceptional power-to-weight efficiency without adding noticeable bulk to your high-performance racing setup.

• Extended Riding Range: Delivers up to 1,000 kilometers (approx. 600 miles) or 20 to 25 hours of active trail and road riding on a single charge cycle, giving you full confidence on multi-day bike packing treks.

• Tool-Free Latch Loading: Features a robust, integrated retention lip that interfaces directly with your derailleur’s tool-free battery latch, locking firmly in place against harsh trail chattering, drops, and vibrations.
