Fast Charging 2600mAh Rechargeable Battery Packs with Charger for Xbox One/Xbox Series X|S Xbox One S/Xbox One X/Xbox One Elite Wireless Controller, Long Lasting Intelligent Protection

They do not have the contacts for the Xbox Elite Series 1 controller so do not work. The product description is incorrect.

Absolutely buy this. And this one in particular. They last forever

Very long battery life on my days off I play all day and I dont need to swap batteries for atheist a week, week and half. Great buy charges quick too

Really good longevity. I play an average of 6 hours a day on the weekdays and I get two to three weeks out of them.

Bought these to use for my Xbox series X I play generally every Saturday night for about 4-5 hours and one battery usually lasts me 3 Saturdays before swapping out and the nice thing is you have 2 batteries so there is always a fresh one and takes a mere 10 seconds to swap out.

Pretty good! Don’t last as long as expected but still neat!

They work great as intended but battery lifes definitely shorter they dollar tree batterys but its nice not having to buy batteries and theres 2 batteries included so while your using one others always charging just wish lasted little longer

It’s good but only one side charges

Good kit for my xbox controllers.

These things have been through some battles with me. Were both still here
