4800mAh Rechargeable Battery Pack for Xbox 360 Wireless Controller

Pros: Much cheaper than the official Microsoft batteries.
Works nicely with play and charge stands / quick charge docks.

Cons: Doesn't stay in the controller properly! Official batteries clip into place, these seem to have a habit of just falling out of the controller. Which makes them kinda useless. Of the 3 I bought, only 1 stays in the controller or quick charge dock properly.

Other: Good battery, poor retention clip. I'll be RMA'ing mine in the hopes that the next batch work correctly :(

Pros: Waay cheaper than any Microsoft-branded batteries, and have a way higher mAH than MS' batteries. Charges well with the play and charge kit, and lasts long.

Cons: It didnt fit the controller as snugly as the MS batteries do. If you take a nail or iron-file and file down the edges on both lower sides of the battery, it fits perfectly and stays in place. Havent had any problems with them falling out yet.

Other: For the price you cant go wrong. It might just not fit like MS batteries, but lasts way longer and with a little modification, it fits just as well.

Pros: It's a battery, and from what I can tell, a very good battery. I got one a few months ago when my original ones started to wear out. I have the OEM dual charging dock, and I put this one into my rotation. Since then, two of my originals have died completely, and this one is going strong. I am getting 2 more right now.

Cons: None, other than to fill up space it has the writing on the back of it, and the originals are blank.

Other: No brainer! Don't be scared... DX shipping is sometimes slow, and sometimes you get part of your order before the rest of it, but it always shows up, is always free shipping, and is always cheaper than even Wally Mart!!!

Pros: Cheap. "4800 Mah" it states...

Cons: The 4800MaH battery doesn't take in any current from the USB-cable charger. I've tried to charge it through powered hubs,directly from xbox/pc (using charging cable) but no dice. I have to keep the cable in the controller all the time.If I remove it, power goes out in about 30 seconds.

Other: Better buy an original from Microsoft instead of this, if the other's are just as bad. Battery now works like a "cable" between USB-cable and controller circuitry. LOL. 4800 000 000 mAh, but cable is always needed. ;-)

Pros: Product works very fine, the price is very cheap, I buyed 3 batteries and I used it for one week and until now working perfectly.
(Para Brasileiros) O produto funciona muito bem, o preço e muito barato, eu comprei 3 baterias e usei por uma semana e ate agora funciona perfeitamente.

Cons: only cons that I find is the build quality. Build quality is not perfect but fit well, and this is only thing that matters.
(para Brasileiros) o unico contra que eu encontrei foi qualidade da fabricação. A qualidade da frabricação não é perfeita más encaixa bem, e isso e o que importa.

Other: Good price, good product, works very fine like microsoft genuine ones. use the charger station to charage fast your batteries and you have nothing to worry about.
Bom preço, Bom produto, funciona muito bem como a original da microsoft. Use o charger station para recaregar rápido suas baterias e você não tera mais nada com o que se preocupar.

Pros: It's much cheaper than Microsoft official one, but it's worse in quality. If you have the USB cable for charging this battery with the controller and your battery gets broken, you can save money by only buy the battery.

Cons: Even in the first full charge, the x360 don't detect the battery at full charge, so you can play less hours than with the official one. It looses charge capacity quickly. Try to charge it fully and dont charge it again until the controler gets disconected to extend its life.

Other: It would de great to find lithium baterys for x360. Until then, this is just fine.

Pros: It's a very cheap product, if you don't expect much. É um produto bem barato se você não espera muito dele.

Cons: The downside is the material, I need to recharge almost at the same rate as my old original microsoft batery, it works for 2 hours at most. O lado negativo é que é necessário recarregar quase na mesma frequencia que a minha bateria antiga original da microsoft, a cada 2 horas aproximadamente.

Other: If you want quality I don't recomend, the lower the price the lower quality is. Se procura por qualidade eu não recomendo, quanto mais barato pior a qualidade.

Pros: cheap as chips, considering how much a battery back costs locally, you could afford to buy five or six, charge them all up and play for as long as you like does the job, fit well inside the controller

Cons: not a huge battery life they feel kind of flimsy

Other: they're good if you dont mind charging them heaps, and at the end of the day, they work long enough to play a decent game, plus if they dont work well after a while, its cheap enough to buy more

Pros: Very Good Price; Very Good appearance; Don't fragile; Work perfectly in everybody control. Muito bom preço; Muito boa aparência; Não é frágil; Trabalha perfeitamente com qualquer controle.

Cons: Low duration, they feel kind of flimsy Baixa duração da carga.

Other: Need i emergential battery, buy it, works perfectly with anybody xbox control, any too the cable, works perfectly too. I buy 20 units for sale, and i buying more and more, good price, for brasilian users custes R$5,00 or less. Necessitando de uma bateria de emergência, trabalha perfeitamente em qualquer controle de xbox, qualquer cabo também, funcionará corretamente. Eu comprei 20 unidades e vendi todas, estou comp´rando mais, órimo preço, sai a menos de 5 reais a unidade.

Pros: Does it job well as an xbox battery. Especially if you look at its price and compare that to the original Microsoft battery).
No problems at all to fit in one of my xbox 360 controllers (two)
I don't notice any difference with my original xbox 360 battery

Cons: First month i could play couple of hours with out recharching the battery, but now (2 months later) i need to charge it every (two) hour(s).

Other: Very good price for an xbox battery, but be aware you'll need to charge every time you play.
