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.

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

These things last for a long time and have a fast charging time. They work better then other battery packs we've tried and are super simple to get set up and use with the controllers. Well worth the cost. Wish we would have had them sooner.

They fit, but just barely. The shape and size is like 101% what the original xbox batteries are, so it's a tight squeeze, but they work.

Absolute trash! DO NOT BUY! The chargers don't work, the batteries look used and broken. They dont fit in the charging base and when charged using the standard charging cable, the battery doesnt hold a charge and both batteries die as soon as its unplugged! Honestly feels like a lick bait scam more than anything.

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.
