I have a few dead DVD batteries and I picked up a bunch of the 18650's to do refurbs about a year ago, never got around to it.
- I had some older DVD batteries with NiMH instead of Lion. I presume it's a bad idea to change the 18650's to Lion? Different charging profile?
- how do you get the DVD batteries apart? It took me about 15 minutes with a screwdriver prying and twisting. I thought about using a cut off wheel
on a dremel tool, but don't want to accidentally cut too deep.
