Se poate, dar trebuie pusa o rezistenta intre minus si pinul pentru termistor. ( cel din mijloc )

Cu un semireglabil de 100K se simuleaza rezistenta termistorului.

Verificati, la acumulator, ce rezistenta este intre pinul minus si cel pentru termistor.

De exemplu, la acumulatorii Nokia este 70 - 80 Kohmi.

Ceva ca aici :http://www.okyay4.com/nevsblog/2014/diy-extended-cell-phone-battery-for-samsung-note/
