SRAM eTap AXS Battery

The SRAM eTap AXS Battery is the rechargeable power source for SRAM’s wireless electronic shifting and AXS components. Designed to be lightweight, compact and easy to swap, this genuine SRAM battery provides a convenient way to keep your electronic drivetrain powered and ready to ride.

Whether you need a replacement battery for your SRAM road drivetrain, a spare for longer rides or an additional battery for your workshop, the SRAM eTap AXS Battery is designed to work across a wide range of SRAM AXS components.

Genuine SRAM eTap AXS Replacement Battery

This is a genuine SRAM battery designed specifically for the eTap and AXS ecosystem. The same battery platform is interchangeable between compatible SRAM front and rear eTap AXS derailleurs, Eagle AXS rear derailleurs and RockShox Reverb AXS seatposts. (SRAM)

This interchangeability is one of the major advantages of the SRAM AXS system. Instead of needing different battery designs for different components, riders can use the same removable battery across compatible parts.

It also makes carrying a spare particularly useful. If the battery powering your rear derailleur needs charging, a charged spare can be swapped in quickly, allowing you to continue riding.

Lightweight and Compact

At approximately 24 grams, the SRAM AXS battery is extremely lightweight. (SRAM)

Its compact size makes it easy to carry as a spare in a cycling jersey pocket, saddle bag, tool roll or travel bag. For riders who regularly participate in long-distance events, stage races or extended cycling trips, carrying a spare battery can provide additional peace of mind without adding significant weight to your equipment.

The battery uses a tool-free latch system, allowing it to be removed from compatible components without specialised tools.

Fast Charging

The SRAM eTap AXS battery can be fully charged in 60 minutes or less using the appropriate SRAM charger. (SRAM)

The charger uses a simple USB-powered setup, making it convenient to charge the battery at home, at the office, in the workshop or while travelling.

During charging, the charger LED indicates the battery status. SRAM states that the LED is amber while charging and changes to green when the battery is fully charged. (SRAM Documentation)

Designed for SRAM Wireless Shifting

The SRAM AXS battery provides power to compatible electronic derailleurs, allowing the wireless shifting system to operate without traditional mechanical shift cables.

For road AXS derailleurs, SRAM states an approximate battery runtime of up to 60 hours, although actual battery life can vary depending on the component, riding conditions and usage. (SRAM)

The battery can be checked directly through the AXS component or through the SRAM AXS app. SRAM’s LED indicators provide a quick way to check the remaining charge level.

Compatible with Multiple AXS Components

One of the biggest benefits of the SRAM battery platform is its cross-component compatibility.

The battery is compatible with:

• SRAM eTap AXS front derailleurs
• SRAM eTap AXS rear derailleurs
• SRAM Eagle AXS derailleurs
• RockShox Reverb AXS seatposts
• Other compatible SRAM AXS components

SRAM’s current product information confirms that the same battery design is used across these compatible AXS components. (SRAM)

This makes the battery particularly useful for riders with multiple AXS-equipped bikes or multiple AXS components.

Ideal Spare for Long Rides

For riders using SRAM AXS electronic shifting, keeping a spare battery in your riding kit is a simple way to prepare for a depleted battery.

Because the battery is lightweight and removable, carrying a second unit does not require carrying a large external power bank or complicated charging setup during a ride.

Simply charge the spare before heading out and keep it safely stored until required.

This is especially useful for:

• Long road rides
• Gravel rides
• MTB rides
• Cycling holidays
• Stage races
• Bikepacking
• Race weekends
• Training camps
• Multi-bike AXS setups

Genuine SRAM Quality

Using a genuine SRAM replacement battery ensures that your AXS components are powered by a battery designed and tested specifically for the SRAM system.

SRAM recommends using genuine SRAM batteries rather than generic alternatives, highlighting considerations around performance, safety and reliability. (SRAM)

For riders who depend on electronic shifting during training and racing, using the correct battery is an important part of maintaining a reliable AXS setup.

Battery Maintenance and Storage

When transporting your bicycle or storing your AXS-equipped bike for an extended period, SRAM recommends removing the derailleur battery and installing the appropriate battery block. The battery should also have its protective cover installed when it is not in use to help protect the terminals. (SRAM Documentation)

Keeping the battery clean and properly stored can help maintain reliable connections between the battery and AXS component.
