2 Pcs Batteries + Dual-Port Charger for SRAM AXS/eTap, The Charger Unit Comes with USB C, Both Batteries can be Quickly Charged at the Same Time, 380 mAh 7.4 V 2.812 Wh for One Battery.

Glad to have the double charger and batteries are performing well for the bike even in colder weather. It was more cost effective solution vs one OEM battery

These have a few hundred miles on them now, no complaints. Way less expensive than the SRAM version.

3 month update: these batteries also seem to last much less time. I'm not sure if it's related to the fit mentioned in the original review, but during the winter (which is hard on batteries) these will not last 10 hours of riding. I had a full battery on Saturday, then the next Saturday I went out to ride and the battery died 5 miles in. Just enough time to be a total pain, but not far enough to warrant a car ride home Original review: I've got multiple bikes with SRAM AXS groups, so I've got lots of batteries all around. Official SRAM ones and generic. These ones are just not built to the same tolerance of the other ones I've purchased. They wiggle a little bit more than id like both in the charger, and most importantly on the bike. I've tried on multiple bikes, and these batteries just don't fit right. However I've used them, and they seem to work fine. However because of the fit, these will be relegated to being in the saddle bag as emergency back ups.

As advertised. No issues so far. Charger is nice. Rode 5 rides on full charged battery. Pulled it because now I have 2. No reason to kill it. Have no idea how long it will last.

I've been running a pair of these for over a month on my SRAM AXS Red derailleurs and no apparent drop in the charge level as indicated on my Garmin head unit. Behavior seems identical to the OEM batteries I used for almost 5 years. Will they last 5 years... probably not, but I see SRAMs now cost over $70 per single battery.

I was warned against buying knock off AXS batteries. These have been flawless and at a fraction of the price. Moreover the charger is USB-C. SRAM only got around to updating to usb-c recently.

One battery malfunctioned and barely holds a charge only a few months after purchase. Bummer, but at least the other one works...

Bought this set for my AXS GX shifter and AXS dropper to have a backup on the trail and so that I could charge both batteries at once. The charger charges both these batteries and the genuine SRAM batteries. I have about 14 hours of riding on the batteries in relatively cold weather (30-40 degrees) and the light on the derailleur and dropper is still green. Since I've never kept track of how long my genuine batteries last (I check the charge before each ride and charge when the lights go red) I can't compare these batteries to the SRAM batteries. But 14 hours and still going strong seems great given the price. Will keep using and update this review if anything changes. Overall - if you're looking for replacement batteries and don't want to pay for genuine SRAM batteries, these seem like they work well.
