[Small,Lightweight] Battery for SRAM AXS Red eTap GX Eagle Force Rival XX1 X01 Derailleur, for SRAM Reverb Seatpost, Colorful, 240mah (Orange)

working good

This battery is compatible to SRAM shifters, I have a Trek Checkpont gravel bike. So, I got caught twice with my shifter battery drained. First time, I was stuck in a high gear riding a bike path and looked like a cartoon character trying to ride. Second time, I was in a hilly section of town and I felt like friggin Popeye trying to get home!!!

Bought this as a backup to permanently keep in my saddle bag since I know I will eventually forget to charge my battery or will leave home with the battery still on the charger.Used it on one ride to make sure it worked and had no issues, but can’t speak to total battery life.Glad I found this smaller option, as it goes unnoticed tucked away in my saddle bag alongside a tool, co2, and a tube. Feels good to know its there to get me home or save a bike trip some day.

They are cheap. One worked, one did not. I'd give it 2.5 stars.

Funcionan muy bien

Garbage. Item failed on first use.

Small enough to keep in a saddle bag and held its charge for when I needed it in a pinch.

Review of: **[Small,Lightweight] Battery for SRAM AXS Red eTap GX Eagle Force Rival XX1 X01 Derailleur, for SRAM Reverb Seatpost, Colorful, 240mah (Blue)**We have four bikes with SRAM AXS components in our household, including three MTBs and a road bike. I haven't had any issues using this non-OEM battery in any of the components. Fit is fine, including in the OEM SRAM chargers, and performance has been great. Note that this battery is smaller that a standard SRAM battery, both in actual size and capacity. A SRAM battery has 300mAh, this has 20% less - 240mAh. It still seems to last a long time, which I would expect given that it is only a little less.This is a perfect battery to carry as a backup, in case your primary battery dies unexpectedly. With the smaller size and weight (we're talking 14 versus 24 GRAMS difference), it is ideal as a backup since it costs must less than a SRAM battery ($15 compared to $50-$60 for OEM).I absolutely recommend this as a perfect SRAM AXS backup/spare battery to keep you from having a tough pedal back to home or your destination with no shifting.
