I bought a 1800mAh unit [...] hacked off the plastic case and made some new contacts with copper tape.

Just out of curiousity: which battery was the one you used supposed to be compatible with?
I did more or less the same, but with an EN-EL5 (IIRC Nikon)-compatible 1100 mAh battery quite some time ago now. Still works like a charm.
Regards,
Chris.

This one: [a href=\"http://www.7dayshop.com/catalog/product_info.php?cPath=777_3&products_id=99199]http://www.7dayshop.com/catalog/product_in...oducts_id=99199[/url]
The width and depth match the Sharp one perfectly, but it's a few mm higher.
Steps are:
1. Hack off plastic case (carefully!)
2. wrap bare battery is masking tape.
3. Make templates to bring contacts from top of battery to bottom, as they are in a different order from the Sharp battery.
4. cut a thin strip of doublew-sided sticky foam and stick to the bottom of the battery. This should be short enough to sit under the case when the battery is inserted into the Zaurus
5. Cut out template in copper tape, and solder to existing contacts.
6. Wrap the exposed copper in more masking tape.
The battery will be held in by the double-sided foam and the tightness of the fit.
Easy!
Obviously, charging will take a long time.
