Has anybody rebuilt one?



Would I be naive thinking that all I need to do is


- Obtain replacement cells


- Gracefully crack the case


- Figure out how to connect the new cells


- Replace the old cells with new cells


- Close up the case

Check the charger as well. A nimh version I looked at recently, intermittent shorted wires on the the charger had drained the battery to internal dendriting or such.

Per mike:

I think it's finally starting to soak in....

Thanks for the detailed account.
