Battery for FOSDEM-85

I have a few unused Nokia batteries, and I was wondering if I can use them to power a FOSDEM-85 Arduino, or even something bigger.
The batteries are BP-3L, 3.7V, 1300mAh, 4.8Wh. They have 3 connectors, (+) (-) (O).
Does anyone knows if it's OK to ignore the third connector?
Is this connector just a simple temperature sensor or a communication protocol?
Any advice will be much appreciated.




Why not? Use them.

The third pin (o) is the temperature sensor and you can ignore it. It is there as a protection mechanism - so you can monitor the temperature of the battery when you charge the battery (if it gets too hot stop charging).
