I took the K2 battery apart, and I took photos, but all the USB jacks on my computer have busy hard drives plugged into them. I could go get one of my 10GHz wireless docking bays, but meh, bedtime. I will upload the photos in the morning...

This time I took photos at various stages of peeling off the sticky parts (the plastic wrapper/label and rather thick aluminum foil or really thin aluminum sheets, however you define the difference).

This battery module had some other unfamiliar brand of LiPo battery in it. It also has Kapton tape insulating it, which is difficult to peel off the "strain relief" cloth backing, so I will leave it and snip the metal leads close to the LiPo battery, and solder the replacement onto those metal tabs.

As I mentioned elsewhere, a really small new battery should behave identical to a really old (but good) original battery. As lithium batteries age, increasing parts of the material becomes inactive (and the inactive part is literally called "rock content" in the industry).

So a small LiPo from a rechargeable device should be no different than what is in an old kindle battery -- the charger circuit and firmware should just work.

I wonder if it is worth bothering to fuzz all the identifying numbers on all the parts -- probably not -- are they going to void my warranty on this used K2 or something?
