I think it would be cool to show a Teardown of the Bose SoundDock Portable v2 Battery.
I agree. These batteries seem prone to failure and I’d like to replace the cells or whatever it is that is the failure point.
Thanks for your easy and concise help.
Battery is repairable.
There are 4 screws under plastic plugs under sticker. They are one way heads :( use force or a drill.
Locking thingy removal - push the cross pin through - pliers or vise grips to grab and pull out completely. Keep an eye on where spring went.
There may be a bit of glue or tape holding cover too.
4 x 18650 Li-ion cells in 2 banks at each side of the charging board which is held down by 5 screws. Some adhesive was used to hold the cells to the back.
Use meter to check. Mine had one cell at 0V so that was the culprit.
Remove any bad cells by cutting the glue about the temp sensors to carefully get them out of the way. Then cut the cell tags - careful not to short anything as there is charge about. I found it faster to cut tags but you could unglue all cells and lift the board and do that way. My replacement cell came from a Dell laptop pack. Glue the new battery in place (I used automotive trim tape as it was handy) and solder the new cell. Reglue temp sensors.
Reassemble with some new screws.
Hi. How do you push the cross pin through? I can’t
Do you know the correct 18650 cells to use? There are many different ines, flat top, button top , voltage, and milliamps capacity. Thanks,
What type of 18650 battery is required? A flat or button top? What amperage, and what milliamperage capacity should be used? To replace all batteries are 4, or 8 batteries required?
It use 4 cells total, any type 18650 should work. Put electrical tape on top of circuit board at the battery taps to prevent short to a circuit board( it will destroy a board) when you are remove batt tabs to battery cells.
