Replacement Battery & Charger for Sram AXS, for eTap Eagle XX1 X01 GX Reverb Force Rival Red XPLR, Charger and Battery

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.

First time writing review. Ordered pair of batteries for sram bikes. Using original Sram charger.One battery shows orange light, it never turns green. After a while I see no lights on charger.Second battery shows red light when I plug it. Tried two chargers, replugging cable multiple times - same red light, indicating battery failure.Sram charged shows solid blue light = adequate power from my power brick.I can see one battery failing, stuff happens. Two failed batteries look like a pattern to me.

I bought these so I can have a spare on my rides. I've had them for a couple years, and I can't tell the difference from OEM.

Bought this kit as a spare to carry around just in case and it’s decent for the price. Battery fits just like the original

I bought this as a backup to ensure I don't have an issue with my primary battery running out of juice when I'm on a ride. Charged no problem and worked as expected when I swapped batteries. I saw some reviews stating that this didn't have as long of a life as the original - which makes sense based on the price. If my SRAM battery dies, I'll prob just by a new OEM battery - but it doesn't seem to make much sense to pay full price for something that won't get anywhere near as much usage...

I was a tad skeptical about these batteries given the price and a few negative reviews. Since the OEM battery was much more expensive AND would take several weeks for delivery I decided to take a chance on these. While I've only ridden about 90 min so far on the new battery and can't comment on battery life, the charging was fine, as is fit, and there is no indication the battery will last significantly shorter than the SRAM.The peace of mind to have a back up is well worth the ~$30 delivered for two spares. I now have a fully charged SRAM battery in my saddle pack and am running one of the MRX batteries in the derailleur. Here's to no more delayed or disrupted rides as a result of a dead derailleur!

Cheap but does not last. Mine worked fine for 3.5 months but will not hold a charge anymore. The savings you get from not buying original goes away if you have to replace the battery every 4 months.

I took the time to test out these batteries before writing a review. I managed to get 600 miles during the course of a month before having to recharge the batteries again. I am a dedicated road cyclist and love SRAM’s eTap system. However, as many other cyclist, I too suffered the dreaded broken tab on my original SRAM rear battery. It’s an issue that seems to be widespread among eTap users.For some reason SRAM believes their original batteries are worth $80, which seems really out of touch, especially when you consider that the broken tab problem is more of a design flaw, rather than an isolated issue with a certain batch of batteries. Having said that, you may run into the same problem with these MRX batteries on the long run, but their affordable price makes it a more convenient and realistic solution. Of course the jury is still out there in terms of battery life, but I can honestly say that for $30 a set, this is a killer alternative to the original batteries. I had no synch issues either with any of my shifters or derailleurs. Highly recommended
