UV Surface Battery for Axs Red etap Sram Force Rival Eagle Gx XX1 X01

Updated Review: I rode 47 miles on Virginia's Skyline Drive. I have attached a picture of the ride profile. I used 3% of the battery when I rode this segment. This battery is legit. Not nearly as many shifts as riding half the miles through the Valley's agricultural country, but still shifting a bunch over a 4+ hour ride. End of Updated Review. I ride through agricultural country in Central Virginia. I am CONTINUALLY shifting with the rolling hills and riding on Skyline Drive. I can get upwards of 400 hundred miles on one charge (I recharge when the percentage gets below 30%). Keep in mind, my rides are in 25-35-mile blocks. I am super pleased with the endurance of this battery especially with the shifting I do on each ride. Note the two previous rides in the pictures to show the rolling hills (lots of shifting).

Great price for this battery. My first month of owning this battery, I rode 33 hours of gravel, and the battery still had about 25% charge to it. That is really good and makes it a great buy!

Received item 11 June. Charged and good to go. I attempted to use on 17 Aug and battery was dead. So i tried to charge it again, and it will not charge. Dead. Not used a single time. Garbage.

What a name......"UV Painting" Battery for Axs , but thank god that google found the sram axs part. Anyhow the battery perfectly fits into and remains in the derailleur body and to the brand name charger. Works. No idea how many charges it cycles before it is done. But so far it has done 10+ hours and according to the very very handy "LCD Battery Tester for SRAM AXS Battery with Immediate Display, Battery Checker for SRAM Battery, No Charging Function." it is at 72%. Really recommend the battery tester rather than looking at the derailleur's green-amber-red lights. And at this price I ride with the fading OEM and a second one of these. Bad juju when out on the trail and the current cassette ring is the same one you are finishing the looooong ride back to your vehicle.

I got one, 2 hour ride from a full charge. On my next ride I was 15 minutes in and the battery died. Would have been bummed if I wouldn't have had the original SRAM battery with me. I'm hoping it's just a defective battery and the seller will replace it. I'll update this post accordingly. UPDATE (03/07/24): The seller reached out to me promptly and offered to replace my defective battery. Within a week I received a replacement. I plan to try it in the coming weeks and will re-update this review accordingly.

I bought one of these for a backup last year and its been fine. I just carry the spare on my bike and just swap out when the level gets low so its gotten as much use as my SRAM. A year later it still holds charge well. I recently lost my branded SRAM battery, and purchased a second one of these. The colors are neat too.

This battery works great as a replacement for the stock SRAM battery. I've used it several times with no issues. Fit and function are OEM.

Not sure what the UV painting means, but the battery is a seamless replacement for the OEM-SRAM battery. I’ve had no problems with it so far and it charges exactly like the OEM battery.

seems good so far!

Seems to work just fine as a SRAM replacement / spare.

Bought to carry a spare when bikepacking. Used this from the start of a route to test its capacity. Made it 750km riding a mix of gravel and singletrack before the 25% red warning light came on.

Tested and working great, not quite the longevity of the SRAM it replaced.

First charge and use. The battery is as light as the original SRAM (actually a hair lighter) and lasts as well or longer. Time will tell, but so far so good.
