My 200 did this, turned out to be a fault on the alarm immobiliser, I disconnected this one night and no discharge

Reckon the solenoid in the door seized and shorted something on the circuit board

But specific I know, but first of all have you had the battery tested?

You may have a cell down on it, if so no matter how much charge you give it, it wont last

try unplugging the glow plug relay. I get this problem now and again but since unplugging the relay its been fine.
Mine has a new batt and alternator fitted,
its worth a try and dont cost owt! it starts perfect without glow plugs anyway so i'll leave it as is
