If I short R7 out and attach the battery directly to ground I get a charge current of 130mA. When connected across R7 (100 ohm) resistor I get a chargING current of 12mA when the transistor is on and 6mA when the transistor is off

Okay.
Then 130mA is about what you should get when the circuit is in the charge mode.
When the circuit is indicating charge and R7 is in the circuit, what are the transistor base and collector voltages?
Are you certain the transistor is connected correctly?
