[NTLK] How important is the Battery's temperature switch

[Smith Woody]

You are correct Tony.  If the thermistor is not present and correctly  
connected the the 2x00 or eMate 300 will not charge the battery pack.
However, he may be referring to the safety component that reduces  
charge if high temperatures occur.

The charge cycle will work just fine without this, but should there be  
a short across batteries plastic melting and skin burning temps can be  
reached very rapidly.
This should never be omitted.
