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.

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

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.

Use before return window is up! Battery low on 2nd ride. Didn’t begin using them until I had had them a month. My OEM batteries probably last 50 rides.

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 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.

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.

Avoid these, they drain much faster than stock and often leave me stranded when in my bag for a while. Official batteries are almost 2x as heavy and actually hold a charge even when not in use

I’ve had these batteries for over a year now and they perform just as well as my SRAM batteries. The star of the show though, is the USB-C dual charger. It’s so nice to be rid of one more piece of micro USB, and why SRAM only offers a single or a quad charger is beyond me. Dual is the most useful.
