Help with disassembly of 401 battery.

[rtbob]

As promised by others I now have 2 dead 401 batteries. How do you get the threaded part off without destroying it? Any hints-help appreciated.

A light touch and a dremel tool.

I found the 401 the easiest so far to take apart if you have a few things handy.
Happen to have a 510 battery? If so you can use that to screw on to the 401 batt and wiggle out. Mine was like no effort at all doing it that way.
If you don't have one maybe pick up a dead 510 from a friend just to use for that purpose.
