battery losing charge overnight!

[JonnyK]

Hi guys,

I have recently bought a new battery, alternator and starter motor..

now,,, I leave the battery on charge over night on slow charge on my battery charger.

once charged I then check the voltages on the battery...
12v - when battery is off.
13.6 - when running
there is also an alternator tester which says all is good.

yet when i go to start my car the following day it is either close to, or flat... something is obviously draining my current. what should i check?!

also i have tried leaving my alarm disabled overnight with no joy.

one more thing to note would be that when the battery is nearing being flat.. when i try to start the car it sounds like it is cranking on full battery.. i.e. it doesnt crank slowly and sound like it is dying.. as if it is just out of petrol.. but wont start! yet when i apply the battery charger/jump leads it starts!!

sorry for the essay guys!![/code]
