The main purpose of the battery is to power the electric starter. It also powers the lights, horn, and accessories when the motor is not running. Once the car is running, the alternator takes over the job of powering the lights etc.. and recharges the battery as well.
The battery in a vehicle is used for several purposes. The heaviest [most current intensive] function is to provide the energy to crank the engine and provide ignition system energy to the spark plugs. The battery also acts as a "filter" between the alternator or generator and the rest of the electrical system, acting as a buffer to voltage spikes and surges. It also provides continuing power, when the engine is not running, to various electrical components [like for example, onboard computers, radio or entertainment systems, parking lights, hazard flasher light warning system, interior lighting, power equiment (such as power windows, seats, door locks), etc.].
Yes - you can run a 1200 watt motor on a car battery - until the energy of the battery is exhausted.
To charge the battery
When you say boat battery if you are referring to a Deep Cycle battery as used to power a trolling motor then no, it is not suitable for use in a car. However, if you are referring to a battery in a boat used to start the engine and it is not a Deep Cycle battery it will work just fine in a car as long as it fits the battery holder, can be strapped down, and the battery posts are orientated correctly.
if you leave any lights on in the car you may cause you a flat battery. if you leave any lights on in the car you may cause you a flat battery.
Only if your motor is not running .
When opened by the starter switch, it sends electricity from the battery to the starter motor to start the car.
It could either be your transmission or your car battery. Most likely you need a new battery for your car.
The battery
A solar engine for a solar car is actually an electric motor. Solar cells on a solar car collect solar energy, which is then sent to a battery or battery pack in the form of DC current. This energy is then used to power the solar car.
Alternator on a car is for re cahrging the battery. So you can have a starter motor without a alternator but you wont get far down the road when the battery runs out of power and the car will die.
Battery powered cars use a small battery to power an electric motor to drive the wheels.
