I'd like to figure out a way to use modern technology cells to re-cell the standard battery case for use with an external charging system.

I think I missed something, but wouldn't newer cells (rechargeable of course) charge inside the duo the same as the originals?

I have done it, but the batteries seem to get damaged by soldering and don't seem to last more than a year or so.
You mean like packing super high capacity Lithium batteries inside and charge it externally?
I would hope the replacements work the same as the original.
First of all, Type I, II and III Duo batteries all take the same cells.
Make an interesting proposal!
Got a side order of EtherDock to go with that?
Honestly, I have no idea of the value of a Lind SuperCharger II these days.
Never had one.
I paid less than $50 shipped for mine only a few months ago. Just wondering, what makes these so helpful compared to other battery chargers?

The problem there is that AAAs are typically of much lower capacity than AAs or 4/5AAs. 900mA is the best I've found easily and cheaply available.
An AA battery measures 51 mm (2.0 in) in length—50.1 mm (1.97 in) without the button terminal—and 13.5–14.5 mm (0.53–0.57 in) in diameter.
