2Pack 4800mAh Rechargeable Battery Compatible with Xbox 360 Controller, Dual Charging Station Dock Charger Compatible with Xbox 360 Controller Battery Pack

Best investment ever! These 4800 batteries stayed charged literally for thirty six house. My son put it to the test. They work amazingly. Easy to put onto you controller, and easy to put back on the charger. Cool thing is you get two batteries. One can be on the charger, and the other one can be in use. Constant play time.

Great item, works perfectly

Absolutely love. Batteries fit the controller good. Kinda hard to put in the charger. Connection is good though! Will be ordering more

Good batteries, better than AA batteries we were using. They charger fast and fit well in our controllers.

Even after seeing poor reviews for these batteries, I decided to give them a try since it’s so hard to find rechargeable ones for the Xbox 360 controller nowadays. I didn’t have any issues with the provided charging system, which gave me hope as others have mentioned that they had problems with it. That hope was short lived.The first battery was an immediate failure as it was only registering as “half charged” when looking on the Xbox 360. The second battery performed a bit better - I only used it to turn the console on & off a few times but after waiting 24 hours, I came back to test it again and it somehow had lost 1/4 of its charge. I chalked this up to not being charged to 100%, but after another 24 hours it had lost another 1/4 even though it was only used to turn the console on & off again.Even though some people had good experiences with these batteries, don’t waste your time or money on these, because it’s obviously a complete crapshoot if you receive ones that work or ones that don’t.

Purchased this product a few years ago and is still working great! Worth the price

Very good but should hold 4 batteries

Purchased for the Wiimotes that I have that I use occasionally enough I don't want to leave AA's in them to corrode, and frequently enough that I don't want to go through AA's all the time, this rechargeable battery pack is one I want to love. The batteries fit inside the Wiimote perfectly, and it powers just fine. Even so, I still can't get past a few things.In order of nitpick to more serious:1. It's a weird design. It takes up more space than I feel like it should.2. The battery life is nowhere near as long as a couple of AA's. I haven't timed it, but I feel like I'm always having to charge these.3. This is the kicker. You have to leave it on and "charging" all the time. Seconds off charge and it seems to drain unreasonably quickly. Taking it off the charge and allowing it to drain completely meant that one of the batteries completely refused to take a charge and I had to jump it (not recommended, can cause damage to the cells).Maybe I got a faulty item, and this is not expected. For the price I'm not going to worry about a return or an exchange even if I discovered the fault within the return window.
