I have the results

Battery with engine at off after 2 day of non-starting 11.66 V

I boosted my car with my jetta and to start it i need to keep the pedal floored at 3000 RPM if not it will not start


car running at 900 rpm (normal idle) 13.10 V
at around 1500 rpm 13.50 v
accelarating the voltmeter went up to 14.05 volts.


at higher then 1500 rpm my batery light goes off......


can my battery go dead ?? is still under waranty
the alternatorr seems to charge okay...(it's been cold the last couple of day -10, -15 maybe my battery needs the full charge)

I let the car on "idle" 1200 for around 45 minutes and i drove it for 10.
My battery is reading 12.18 and it's starting after i shut off the engine.. but is a bit warmer then the last couple of days.

i will plug the block heater over night from now on ( first i have to test the block heater a quick visual inspection showed no cracks or aother suspect activitys on the wire..)
