And what should be done on the SX210 in order to convert it from NiCD 
to Lithium ? I've done a conversion (but a capacitor and replace a 
resistor with a diode) on a Korg Polysix, but the battery circuits are 
different.

The diagram of the battery section is here:

Thanks !

On my 240 I used a "AA" size battery holder and found a 3.6v lithium battery in the AA size. Used silicone glue to secure the batt holder to the pcb and ran the leads (with a diode in series, 1N400x will do) back to where the original battery tabs soldered down. I'm sure there's a fancier way to do it, but it works just fine. The series diode keeps the charging circuit from attempting to charge the lithium battery.

Thanks,

can you be more specific ? All that have to be done is to replace the
NiCD batt with lithium and place a diode in series ? no other 
components should be changed ? What about the 1.5K resistor that 
connects to the Batt, should it be removed ? Should the anode of the 
diode connect to the positive side of the battery ?

BTW, the schematics can be found under the Files section
