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.

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Have two bikes with SRAM AXS and needed backup batteries *by C***H on 15 October 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. ### ⭐⭐⭐⭐⭐ Excelente producto *by E***Z on 24 May 2025* Funcionan súper bien ### ⭐⭐⭐⭐⭐ Race-test outstanding, initial testing successful *by C***S on 30 May 2022* Previous reviews had me a little curious on whether these would work, but they arrived on time, charged fine and the derailleur accepted them no problem so... yeah? \o/ I will take them out for race ride testing tomorrow and if I do not have to switch back to the original battery in the 90 minutes or so I will be riding then they are fine. I was more looking at a "bring me home in case I forget to charge the original battery" solution , so any downsides from here on which are not including running for less than 90 minutes would be acceptable given the original replacements go for 90 to 120 bux and these were 40 for two of them. ## Frequently Bought Together - MRX Solutions 2 Replacement Batteries for Sram AXS, for eTap Eagle XX1 X01 GX Reverb Force Rival Red XPLR, Just The Battery - Dual-Port Charger for SRAM AXS/eTap Red Force Rival GX Eagle Battery, Both Batteries can be Quickly Charged at The Same Time, The Unit Came with USB C - SRAM eTap and eTap AXS Battery --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.fi/products/424440499-mrx-solutions-2-replacement-batteries-for-sram-axs-for-etap](https://www.desertcart.fi/products/424440499-mrx-solutions-2-replacement-batteries-for-sram-axs-for-etap) --- *Product available on Desertcart Finland* *Store origin: FI* *Last updated: 2026-07-30*
