Did you get this issue solved? I'm having the exact same problem with one board in a twin Time Crisis 3. Reflowing the battery socket didn't work either and I tested voltages at the socket solder points. Both boards read 3v.

Thank you

Going to extend this a bit. Is it possible the OP was using a s246c motherboard because those and 256 contain an additional 5.5v .1f supercapacitor (exact same as Naomi) that isn't present in s246b and earlier. Both Time Crisis 3 board assemblies use s246c motherboards.

If leakage is a concern, then I should also remove the supercabs for both boards in a twin Time Crisis 4 as well.
