Even though its a new battery, it may be the alternator!! the easiest way to check it is to get it started when running, take the negative cable or black cable off of your battery if it stays running your alternator is fine if it dies the alternator is bad!! the alternator helps keep the battery charged and going!!
You might need a new battery. You might need a new battery.
Disconnect negative cable first from old battery and connect it last when installing new battery.
Correct, a car will not start with a disconnected battery
you have a bad car
you drain your battery when you leave your lights on
if you can start car pull off the neg battery cable if car stalls its the altinater if it stays running it might be the battery
If the battery has a defective cell it might not allow the car to start with a charger. Have the battery tested.

No, a defibrillator will not jump start a car battery.
Depending on what you mean there are two answers. A car being jumped with cables on backward will short out the car either blowing the electrical system and or causing sparks. If you are installing a battery in your car and you put the cables on backwards then you will either drain the battery or short out the car.
Your battery might be dead. Or you may have a faulty starter relay switch
If you use too small of a battery in the car, there might not be enough amps to start the car. You could also damage electrical components in the vehicle.
