Very satisfied with my transmission, the battery lasts for many kilometers, super.

Seems to be the same as the newer AXS battery

2025/12/25

John

The cost of the Red eTap battery is less than the AXS branded battery. They both fit the newer components and the older Red equipement. I wasn't able to find any info about the specs to compare, but I'd stay with the Red eTap option until it's out of stock. This one works just as well as the newer option, but is cheaper.

Good battery

I'm new to the AXS system so have 'range' anxiety at the moment. The easy solution is to buy a 'spare' and pop in your backpack. So that's what I've done. I can now run the mech and dropper till they die and know I won't be caught out on the trails. Happy days.

Maria camilla

Hello, why does this battery cost less than the 86? What are the differences?

Answer of Aitor

In short, the cheaper battery likely has a lower battery health or capacity than the 86% one, meaning it will last less time on a charge and have a shorter lifespan, which is reflected in its lower price.

2023-10-31

Judite

Is this battery compatible with the "Sram Eagle AXS" battery? Thanks

Answer of ARCADIO

YES, IT IS COMPATIBLE. The SRAM battery is the power source for the eTap® or AXS™ components. The same battery can be swapped between eTap® AXS™ shifters and derailleurs, Eagle AXS® shifters and derailleurs, and the RockShox Reverb AXS™ seatpost.

Hi! I see another similar product that costs twice as much: https://www.tradeinn.com/bikeinn/es/sram-bateria-axs-red-etap/141330818/p What´s the difference? Is it an original Sram product or a copy?

Answer of Aitor

The battery lasts longer

Answer of Alexandre

These are definitely SRAM products. It must be an older batch since the batteries are a little less efficient over time. I ordered some and the cheaper ones work very well.
