It is the HV battery that starts the engine, not the 12V battery in the '09 FEH. If your HV battery is that low, you need to talk to your dealer and have it tested.

Without the HV jump start system, you have two options:

1) Open HV battery up and manually charge it with a high voltage, low current power supply.
2) Take it to the Ford dealership where they can use a special charger to charge the HV battery. Good chance the techs won't know what they're doing.

Good luck,

Steve
