Measure the voltage across the battery with a simple multimeter. Before starting, a battery in good condition should show better than 9/10 volts approx. Once started the same check should produce a reading of 12.5 - 15 volts, typically 13/14 volts, as the alternator charges the battery by putting a higher voltage in. My 9000 has this basically built into the computer - before starting, it usually shows 9.5+ volts, once started it shows 14+ volts, slowly dropping as the alternator recovers the starting drain on the battery. This assumes no other electrical accessories are switched on.
