You may 'fool' the PMIC by running a 10K ohm resistor from the center pin(2) to ground, on a two wire system, and then the PMIC will charge the battery.
(hope this helps you)
ThankX Mark, I'll try that. At least I now know.

Mark, Should I use a thermistor or is it safe to just use a resistor?
A thermistor doesn't buy you anything because its not mounted in the battery package. You may use a standard half watt 10K ohm resistor.
Mark, I just got back here and saw your reply AFTER I picked up 100 10k Ω 1/4 watt resistor is the 1/4 watt good enough?
Yes, it probably is going to be just fine. If you want to make sure (I have not measured it) you can measure the current by taking a voltage drop reading across the resistor-- do the math, if voltage times current is 0.250 or less a 1/4 watt resistor will work fine. Its really a pull-down resistor to ground and not much current passes through it I suspect.
Got it Mark, ThankX.
