    Had to take the battery out, as it totally died (Blade 14", 2013) and refused to power on with the battery still connected.

    Frustrated at not being able to find a replacement, I decided to take it apart to find out if there was anything complex inside.

    Turns out there's a little circuit board in there, alongside the six very cheap-looking cells. They're held together in the black plastic frame with the outer black plastic wrap.

    There's no real "so what" here, just thought you guys might find it interesting!

    Cheers,

    That's how all li-ion pouch cell battery packs look like; every ultrabook, table and smartphone has the same design and 'cheap-looking' cell(s) once you peel away the plastic.

    Larger and/or older laptops use 18650 cells instead of the pouch-type and cannot expand/inflate. The controller pcb (with charging circuit and overvoltage protection) is the same though, as are the voltages.

    Anyway, you now know that you need six 3200 mAh pouches in order to make a new, working battery pack. Measure their height and width to make sure, but other than that these 3200mAh cells look like a good match. Swapping them only needs a soldering iron since they're all tabbed. Just be careful not to short them while you're working; all leads are 'hot'.

    Very interesting to see the inside, too bad there are not many markings on the pouches. I am curious who is manufacturing those cells. Even though those pouches often look the same, the chemistry decides how reliable they are. Thanks for the photos!

    Just don't puncture them pouch cells, unless you like fireworks.
    One of the cells may have died (only takes one to kill a pack), or it could be a problem in the control board.
    Get you a meter and check the voltages on each cell.

    Definitely dispose of it properly. If you're in the US staples and the like have free battery disposal. Those batteries can be dangerous in the normal garbage. Especially to sanitation workers.

    Yes it will act like Frankenstein when disposed in garbage can and torturing everybody by deciding to self destruct anytime.
    The OP was really lucky the battery didn't cause any harm.
