Hi all,
I know there's a couple of pics floating about on the forum about how to disassemble the mini0806, but I thought I'd supplement those existing images.
Some background. My cam was purchased around 6 months ago from the guys at SportGPS, who have been fantastic. In the last couple of weeks the camera has started shutting down after a couple of minutes running, and rebooting for a few minutes then repeating.
After searching the forums and a bit of diagnosing (powering the cam directly rather than through the GPS mount) I concluded that it was likely the battery.
I spoke to Mike at SportGPS who indicated he was happy for me to replace the battery under warranty, so I went about sourcing and replacing the battery.
1) I purchased two of these of eBay (expecting that the battery in my other mini 0806 would go soon too):
3.7v 300mAH LiPo battery, with slightly smaller dimensions than the original.
2) Opening the case was pretty simple thanks to the photos already on the forum - turn the mount to line up with the lens, then pry of the power button shroud with your fingernail, running around the outside. A jeweler's screwdriver may come in handy.
3) Once off, unscrew the four screws underneath, and the end cap comes off:
4) next step is to carefully slide off the mount ring, being conscious of the wire underneath (in this photo you can see I've marked the original mount position with white-out too). Be aware that when this ring comes off, there is also a spring loaded ball bearing adjacent to the indicator LEDs that is *very* easy to lose track of.
5) With the mount ring off, it is simply a matter of working your way around the outside of the case halves, separating the lock tabs:
6) the screen-half of the case is tethered by the screen cable - flicking the grey section of the socket up and away from the ribbon will release it:
7) this should allow you to remove the circuit boards from the other case-half.:
8) The battery is housed between the two circuit boards - you will need to gently and carefully pry the two boards apart. There are 3 sets of pin-socket connectors, slowly work your way around each of them opening the gap slightly with a jeweler's screwdriver (in the photo above I'm already part way there, but here's some other photos of the connectors):
9) eventually (be patient), they will separate, revealing the battery which is held down with a small double-sided sticky pad (not shown):
10) The battery is connected to the circuit board on the other side to where it's mounted - the wires run around a sharp corner to fit inside the case:
11) the black wire is obscured underneath the red:
12) unsolder - resolder and re-use the sticky pad to mount the battery paying close attention to the routing of the wires. Here's the new battery top, compared to the old:
13) reassembly is simply the reverse of the previous steps, paying particular attention to compress the ball bearing into it's enclosure prior to pushing the mount ring over it. The first time I tried it shot across the room - panic ensued.
14) test - in my case, no more rebooting!
Good luck!
