battery terminals [Nokia BLB-2 Spare Battery - 102209]

Why you need the 4 terminals in this battery ? + , - is OK , but for what you need the other 2 terminals ? What is the value of the internal thermistor ?

the other 2 terms are for battery temperature sense & charging level sense. The internal thermistor value is on the order of 47k - I think, I've not had to check one for a very long time.
I kind of have the same question, How do you have to use the batery in a self-made aplication? Do I have to use all the contacts on the battery? And which of the 4 contacts are positif and negatif?
