I had recently switched out my alternator and battery to try and resolve the issue although that didn't work. When I start my car the engine rolls over but doesn't fully start. The head lights work and the radio as well as the dashboard turn on too. I use a battery booster to start the car otherwise I cannot start the car. The battery voltage on my car is always above 15.0 as opposed to the regular 14.0, does anyone else have the same problem and/ or has any solutions? Another issue with this problem is that it is not consecutive although, it happens quite frequently. Some days i can go the whole day without the battery draining and not needing the booster while on others I need it every time I want to start the car.

:welcome:

15.0v while running is normal. Especially after a start. That's alternator output.

What is the static (battery) voltage? If it needs a boost to start it, it sounds like a weak battery.

is the battery draining or do u have maybe a bad starter and cables drawing too many amps?????

=======================
15 volts is NOT unusual - particularly with a weak/discharged battery -

very possibly a "new-defective" battery -
what brand/style/model did you get -

have it load-tested -
