Xbox Controller Battery Pack with Charger Kit for Xbox One/Xbox Series X|S 4x1400mAh Rechargeable Battery Pack, Xbox Accessories

these work on the controllers that came with the game systems that the older rechargeable batteries for the controllers didnt work in. and still work in the older style ones too. great deal for the products. highly recommended

works great batteries last forever

My son wanted this for his controllers because he was burning theough batteries. He is happy and I am happy Im not having to buy 16 batteries every 2 weeks.

My kids love it they can charge a set while playing with the other set and at night all 4 go on the charger. Batteries work great we've had them over 3 months and still going strong!

These batteries are great!! Work well with Xbox series x. Totally worth it. Saves tons on disposable batteries. I never write reviews btw. But I read them so I thought maybe I could help somebody else out.

we love these i enjoy always having fully charged batteries on hand. they charge fast and hold a decent charge. simple to switch out of controller when dead

At first they worked very nicely but over time they start to run out of battery quicker and even when your not using them they lose power. But they fit my controller perfectly and don't stretch it out at all and with these you don't have to buy a new back for your controller like some other rechargeable batteries.

Batteries had trouble charging right off the bat. Often not being recognized by controllers. More recently, one has exploded, leaking battery acid all over the charger. Compelling me to leave this review.

did not work in any of my electronics. do not buy

Does not work batteries come dead, not holding a charge and not turning my controller on. Do not buy
