BQ27742-G1: Deeply discharged battery

Hey team, 

I wanted to clarify PCM behavior for a deeply discharged battery that is <1.4V. From below, the fuel gauge IC will allow trickle charging if V_BATT > V_LVDET. 

What happens if the battery is below this threshold? Will CHGFET open permanently? Is there a way to recover?
