Could be that the Alternator in the vehicle is not working? When you got your NEW battery, did you have it fitted or did you do it yourself? I would have the Alternator checked at an Auto Electrician.

If you have a multimeter, start the car and check the voltage reading at the battery terminals. If it's at 13.5ish volts the alternator should be working and charging the battery. Assuming you have been running the car...

If you haven't run the car there might be a short somewhere which can drain the battery. Were the parker lights left on?

Probably one of the Diodes inside the Alternator diode pack could be shorted, causing the drain on the Battery. Will still show correct output voltage but not correct current output.

Easiet way of checking to see if its the Alternator while its running pull the positive terminal off if it stalls the alternator is buggered.
