## Description

desertcart.com: MRX Solutions 2 Replacement Batteries for Sram AXS, for eTap Eagle XX1 X01 GX Reverb Force Rival Red XPLR, Just The Battery : Sports & Outdoors

Review: Have two bikes with SRAM AXS and needed backup batteries - I own a MTB and Gravel bike both run Sram AXS. Each came with a SRAM branded battery. I also have a road bike with Shimano Di2. The Di2 battery lasts months while the SRAMs run about half of that. But the SRAMs are easier to remove and cheaper to replace. Although these MRX versions are much better value. Due to the shorter battery life I needed to start carrying a back up. Found these and saw decent feedback and have had no issues so far. Some claim these do not last as long as the SRAM branded batteries. My guess is they likely come from the same factory. I have not conducted any rigorous testing to determine if they are better or worse but for the much lower price it is a no brainer to have 3 or 4 of the MRX on hand.
Review: Great old batteries New ones not so much… - I’ve had these for three years! They have lasted great! Still charging and working well! I’m buying them again for a new derailleur that came without batteries.

## Questions & Answers

**Q: How long does it hold a charge if I keep it in my bag as a spare?**
A: (Perhaps overly detailed answer). I charged two of these batteries and a genuine SRAM one at the same time. I got 18 hours of riding out of the SRAM one over a 5 week period. Then I put in an MRX (5 weeks after charging), and got 12 hours over 4 weeks of riding. Then I put in the second MRX (now 9 weeks after charging) and got 8 hours. So, they seem to hold a charge well enough to use as backup.

**Q: What is the warranty on the batteries?**
A: No Warranty

**Q: Is this battery compatible with the sram etap charger?**
A: I believe it’s the same charger for AXS and etap

**Q: What is the warranty on these batteries?**
A: I don't know but for the money, just buy it.  I haven't noticed the difference between it and the SRAM battery.

### ⭐⭐⭐⭐⭐ Have two bikes with SRAM AXS and needed backup batteries
*by C***H on October 15, 2023*

I own a MTB and Gravel bike both run Sram AXS. Each came with a SRAM branded battery. I also have a road bike with Shimano Di2. The Di2 battery lasts months while the SRAMs run about half of that. But the SRAMs are easier to remove and cheaper to replace. Although these MRX versions are much better value. Due to the shorter battery life I needed to start carrying a back up. Found these and saw decent feedback and have had no issues so far. Some claim these do not last as long as the SRAM branded batteries. My guess is they likely come from the same factory. I have not conducted any rigorous testing to determine if they are better or worse but for the much lower price it is a no brainer to have 3 or 4 of the MRX on hand.

### ⭐⭐⭐⭐⭐ Great old batteries New ones not so much…
*by M***Y on December 7, 2025*

I’ve had these for three years! They have lasted great! Still charging and working well! I’m buying them again for a new derailleur that came without batteries.

### ⭐ Time will tell
*by C***G on May 20, 2022*

UPDATE: As I noted below in my original review "Time will tell". It did. Less than 4 months of use (switching back and forth between this battery and the original SRAM battery) and now this battery is so loose in my XX1 derailleur that the contacts come disconnected and my shifter randomly works. It still seems to hold it's charge, but their must be something slightly different in the plastic on this battery that has worn in this short period of time. Originally 4 star review below, but now a one star due to it not holding up and randomly working. I've utilized this battery for one 25 mile ride. It worked well over that duration. Verdict is still out on the longevity as compared to the original SRAM battery. I had no issues with this battery charging in the original SRAM charger and no compatibility issues on my xx1 derailleur. All worked seamlessly. If the longevity is not good it will still make a great back up battery.
