This is my first experience of using a MTB equipped with a SRAM electric derailleur.
Hello, I bought this product out of necessity (to replace a battery fitted to a SRAM Eagle 12-speed AXS Eagle derailleur). This equipment was on a Mondraker vttae that I bought second-hand at the beginning of December 2025, bearing in mind that this vttae was bought new in January 2023. So, if the battery is original, the life of this battery was three years. I'm not a specialist in this area, so I can't say for sure whether it's a weak point or not. I tried to recharge the faulty battery beforehand, but to no avail. That's the end of my experience... Sincerely

Top experience again with Mantel
Wonderful to be able to shift gears carefree again with a new full battery

Good replacement, hopefully it will last longer than the battery this is a replacement for
Great replacement for an old SRAM Etap battery. Unfortunately, all my old etap batteries failed due to the plastic tab breaking off. Not through misuse, but a bumpy road....

Do the job like the original.
Serves as a backup battery under the saddle in case of power failure.
