Hi all,
I have recently been given a dead iPod Nano 2G to play with and have this evening stripped it into it's component parts. I have the housing, LCD, motherboard, click-wheel-thingy, LiPo battery all separated and have been looking for info as to which parts I can salvage and use for my own projects.
During browsing, I came across some very stern warnings about LiPo batteries - over charged/discharged cells, punctured cells, bent cells, overheated cells being susceptible to balooning/catching fire/exploding as long as up to 24 hours after damage.![Eek! :eek: :eek:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
This iPod had been wet previously and evidence of a little electrolysis was found on the docking connector on the motherboard. Also, electrolysis was found around the charger/temp sensor IC's, so that board was removed and the cell checked for voltage. The cell measured around 2.6V and that, combined with some degree of flexing when removing it from the motherboard, led me to beleive that I may have a potential problem after doing a little research.
Sooooo, the cell is now in the back garden with the terminal strips taped up, inside a taped up tin, with a brick on top.
Am I being over-cautious?
I haven't used LiPo cells previously, so don't really know how to handle them.
What would you do with it?
P.S. I haven't tried to charge it.
