YCCSKY 2-Pack Rechargeable Battery Pack for Xbox Series X/S & Xbox One X/S/Elite Series Controllers, 4440mWh (1200mAh) Long-Lasting Power Overcharge/Short-Circuit Protection, FCC/CE Certified

I charged them once and they haven't even gone under 50%. Super easy to install and charge. Easy to install and charges fast. 100% Would buy again

This product works just the same as the Xbox brand one and it fits perfectly! I thought I was only paying for one and they came with two of them!!! Nice

2/11/22 update - seller sent out a replacement free of charge. Replacement works great. Thank you so much and appreciate the fantastic customer service.It does not fit on an Xbox one controller. I bought these back in the summer but just finally had a chance to use them. Charged them up and when ready to put them on the controller, they don't fit. They look to be for a completely different controller.Now I'm stuck with rechargeable batteries that I can't even use.Don't spend your money if you're looking for something to work with Xbox one wireless controller, because this doesn't.

I like that you get 2 batteries for a very reasonable price. They last a long time and they can be recharged through the plug on the controller with a usb c plug. I recommend .

I'm a heavy gamer. For the price, you will never be without a charged battery. One of the best purchases I've made in recent memory.

Do not buy didn't come charge from the factory won't take a charge and to get them returned would cost just as much as you would to buy them again do not waste your money

Does not last nearly as long as my older batteries. Works great for about a day of barely any use then needs recharged just about every other day. Price is fine for what they are but will spend more for better quality on a different brand.

Unfortunately, for this time of year, my delivery got a bit fumbled. Which I do not blame the seller for at all.That being said, when my order finally did arrive, it was complete with the two chargers and split charging cable and ready to charge/go. I bought these because of the growing demands my kids were putting on purchasing batteries (they would leave them on and go do something else, as kids do).A word of caution though, as some have may have read in reviews prior to mine: The battery packs have the "covers" built in, and because of this, they slide VERY snug in the controller housing. I personally liked this, given my situation, because it's harder for my kids to remove and lose... just be mindful when putting them on the controllers.100% Satisfied with my purchase for the price vs. quality, and DEFINITELY recommended for those trying to save some money on batteries with gamer kiddos in the house.Thanks for reading.
