If you are iterested in knowing your battery voltage

This is one way to monitor it or you could buy a voltmeter.
A voltmeter is cheap but you would need to measure the voltage at the jump points under the hood.
Under 11 Volts is the place where it starts to give you and error message I believe.
You can probably get a cheap Digital voltmeter at Radio shack or on line for 10 to 20 bucks.
