Xbox 360 Battery Pack Disassembled

I’ve had an official Xbox 360 ‘Play & Charge’ kit for a year or so now, and the battery life has slowly but surely dropped to nothing over that time. I decided to take it to pieces to see if I could figure out what was up with it. As you can see from the image below, there’s not a lot to it.

Xbox 360 Battery Pack Disassembled

The two halves are just cemented together – you can see the “dashed” effect the cement has left in along the edges. If you want to open one up, you just have to force the two halves apart with enough force to break the bond between them. At least that’s what I did!

There’s (what I assume is) a thermistor that sits between the cells for monitoring their temperature. It’s also fairly obvious the battery pack is just two standard 2100mAh NiMH AA cells. In my case, I assume that one or both of them has stopped working so I’ve ordered some new ones. Hopefully I can just drop them straight in there and all will be good once again. Stay tuned.

  1. That’s a really interesting find. Now I think about opening my Play & Charge kit too and replacing it with some real rechargables. Do you have any idea if the batteries you found are LSD-NiMH? From the picture it looks like these are plain NiMHs so replacing them with like Sony’s Eneloops cooul really optimize performance of the kit.
    As it is right now, the self-discharging of my Play&Charge-Kit is terribly annoying.
    Please post updates of your efforts!

  2. Look at the science behind that thing, its sooo complex, well worth the £15 ;)

  3. Hi Thomas, thanks for the reply.

    Yes they are just ordinary NiMH cells by the looks of things. The ones I’ve bought as replacements are slightly higher capacity (2500mAh) so hopefully they’ll last a bit longer.

    I think you can get 2900mAh cells for just a little bit more money.

    I’ll do another post with some results when I put everything back together!

  4. One small hiccup, the batteries are spot welded together. Most battery shops can do this for you for a couple bucks. (worth it considering how many times controllers are dropped, thrown at the other players, etc) You could solder them but solder joints are not as strong, might not fit in the compartments, and you can damage batteries when soldering. The heat required to get the solder to flow can also be bad for them. (Most cordless tools have thermistors, but it depends if it’s used for protection of the cell or guaging of the charge level ni this application.)

    Now the hard part, gluing them back together.

  5. Could you please take more photos of that thing under the batt ? Hope everything works fine for the replacement.

  6. You don’t need to spot weld them or soldier them back on, I just took not at where the batteries and direction they sat in and the wires are being held in place by the pressure of the batteries.

    Also my packs had Sanyo 2100′s in them.

    I have charged and used it once so far, also I am just using electrical tape to hold the housing together. I prob won’t mod another one since the packs are so cheap.

  7. James, did your pack work after you replaced the batteries? Dumb question, but I would like to know. My xbox 360 controller has stopped holding its charge and since it’s a red controller, I can’t get a replacement battery pack.

    Could you email your reply to: [email protected]

    Thanks a bunch!

    Have spent two days resaearching this problem. Am about to fire up some serious car battery cranking amps through to see if I can reset the battery memory on the little suckers. Will let you know if I have any success. BTW, this has been the first site Ive seen seriously address this issue by actually opening the battery up. Good work!

  9. Hello, my youngest son dropped my controller and the battery stopped working, it was near new and will not charge with the cable or a quick charge kit. Any idea?
    Cheers

  10. how did u dissasemble it :?:

  11. This fix does work for batteries that refuse to charge.
