Is a voltage drop like this in 3 min to be expected?

Put the multimeter on the battery whist it's cranking, if it drops below 11v then the battery isn't going to start it, it's toast. Try jump leads from the car to get it going.
Is it turning the motor fast enough or is it relly sluggish?
To test for a voltage drop at the starter motor then test across the battery +ve to starter stud and crank the engine, it should read no more the 0.6 volts.
If the results are massively high then there's a bad connection at the leads or solenoid.
Then test across the battery -ve to starter casing and crank the engine, it should read no more the 0.25 volts.
If this is high then there's a bad earth somewhere.
