MRX Solutions 2 Replacement Batteries for Sram AXS, for eTap Eagle XX1 X01 GX Reverb Force Rival Red XPLR, Just The 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.

They work well. I've had the pair in circulation and they work as well, or maybe better, than the OEM AXS ones. No issues with fit or compatibility. Battery life seems equivalent. I just keep a spare one of these in my bag and swap it out when the derailleur reports low, which is about 3 weeks of heavy riding (and two days before a race, just to be sure).

These batteries are terrible. Bought them for spares after my seat dropper died on a ride. Charged them for one cycle and they died fairly quick and now it will charge for about 15 seconds and then the light goes out in the charging base. Total waste of money. I should have just bought OEM.

These are a low-cost replacement for the SRAM AXS batteries. I only use these for a RockShox AXS dropper post, not shifting, but yesterday (I've been using these for several months) I found that my dropper post wasn't actuating every time. When I examined everything, I found that on two of my batteries, the little tab on the bottom had broken off and so the battery was wobbly in there and the contacts were sometimes making contact, sometimes not. I'm not sure if this is an issue only with these off-brand batteries but from the two with the broken tab, it appears that the tab was glued in place and not part of the plastic casing. When not in use, the batteries are in their charger or have the red cover on them. But, of course, I can't find the tab that's broken off somewhere so I can't glue it back on and am not sure how trying to make a little tab will work, so I guess I need to buy new batteries now.

Does exactly what it needs to . . . . powers my SRAM AXS products. I have used these batteries for over a year. I leave them in my car so they get cold in the winter and hot in the summer. They just work. I read the reviews knowing that it was a gamble choosing this product. I'm shocked to say they work just like my SCRAM branded ones.

Out of the box, one battery appeared to be about fully charged and got a green light from the charger but the other almost immediately got a red light. Breaking out the multimeter, the first battery read at ~7.9V and the second battery was completely flat. Luckily the internals were pretty easy to get out without excessive force and of the two 400mAh cells in the dead battery, one read ~3.8v and the other seemed totally DOA. There is definitely a small amount of gas causing a bubble in the dead cell. Overall the rest of the unit is reasonably well made, so my guess is that they test them at the factory but the cheap cells just maybe have a higher failure rate. Bummer! You get what you pay for.

Igual que la originales, excelente durabilidad

Why by the sram ones when they cost so much. These last about the same amount of time as factory ones. Would recommend.

Bought these for when I forget to charge the seam batteries that came with my bike. They perform well and I can’t tell much of a difference in ride time between these and the sram batteries. Price is very good.

Funcionan súper bien

Artículo de muy baja calidad. Queda más pequeño que el origina Lo cual provoca un falso contacto y no funciona correctamente

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.

I am pleasantly surprised by these batteries. They seem to last as long and the stock SRAM batteries that came with my bike. I bought them as "just in case" spares, but have no issues interchanging them with the stock SRAM ones. Would buy again.
