There's no logic in the battery. There's just one resistor or NTC.

I was pretty sure that was an NTC to monitor the battery's temperature and prevent charging if it gets hot. But I could be wrong -- looking around a bit turns up references to both roles, and if it actually is a resistor to specify size, it would explain the wierdness.
