SRAM AXS Battery Guide & Titanium Upgrades

SRAM AXS uses a single removable battery across derailleurs and blips. Keeping it charged is simple — but if you run SRAM eTap, there is a hidden weight-saving opportunity most riders overlook.

Step 1: Understand the SRAM AXS Battery

The SRAM AXS battery is a rechargeable lithium-ion unit that clicks into the back of your rear derailleur, front derailleur, or BlipBox. One battery fits all AXS components. A full charge lasts roughly 60 hours of riding, and charging takes about one hour via the included USB cable. When the battery drops below 10 %, the LED on the derailleur flashes red.

Step 2: Extend Battery Life on Every Ride

• Remove the battery when transporting the bike — vibrations can slowly drain it
• Store spare batteries at room temperature; extreme cold reduces capacity
• Carry a spare on long rides — it weighs under 25 g and swaps in seconds

Step 3: Save Weight Beyond the Battery

While the AXS battery itself is light, the stock SRAM Red eTap shifters carry unnecessary weight in their clamp rings. TiNE titanium shifter clamp rings replace the OEM steel rings at just 9.6 g per pair — that is 22.8 g lighter than the stock SRAM Red clamps. It is one of the simplest weight-saving swaps for any SRAM wireless groupset, and the titanium rings will never rust or corrode.
