Today, we are taking apart a bluetooth headset by the name of Bluetrek Skin. Contrary to the name, there appears to be no epidermal tissue on this headset anywhere. In fact it seems to have more of a plastic exoskeleton. Truth in marketing out the window...

And we now present, a battery.
There's a nice RoHS sticker there, suggesting it contains hazardous substances (couldn't possibly be referring to the combustibility of Li-ion batteries, could it?). Better not open it.
The battery is held in place with a weak adhesive. Just pop it off with your fingers.

Edit Step 8 ¶
And now, some obligatory close-ups of the circuit board.
The identity of chip in the center of the board (second photo, in the red square) has eluded me for quite a while. The logo appears to read "CSI" but it actually turns out to be "csr". Given the size and mounting, it's probably a BlueCore4 series (not sure of the exact model).
This one chip handles pretty much everything. It contains the radio, baseband, and microcontroller. It runs off 1.8V to 3.6V controlled by an integrated voltage regulator. It supports v2.0+ EDR and can coexist with nearby 802.11 (WiFi) networks. It can even work directly with up to 8Mbit flash memory (according to the specifications, given the 8x8mm size of the package (mind out of the gutter please), it's likely external to the chip).
There could be something under the board the main chip is mounted on, but I don't have a way to get to it.
There's a few mentions of Innovi on the board. According to LinkedIn, Innovi might be either Bluetrek's old name or their parent company.
