What brand is the car?

The battery "starts" the car...after that the alternator keeps the battery charged. They work together in other words.
Yes, the battery starts the engine, and as long as the battery is fully charged the engine will start. The battery will loose it's charge if the alternator is defective and not replenishing the charge of the battery but the alternator has nothing to do with starting the engine.
Try having battery charged It may have been discharged to the point that it will not accept a charge and willhave to be replaced After having battery charged check the alternator with a voltmeter - should read approx. 12.8 without engine running and 13.8-14.2 with engine running
No. That will not charge your battery. Alkaline batteries tend to get a film over their electrodes. Sometimes you can get additional usage from them by using a pencil eraser and removing that film. Apparently clothing removed the same film. It did not recharge the battery but removed the film to give the battery a little more usage. The battery that appeared discharged was not far from discharged. When it starts giving off that film, it is almost gone. It is not far from completely gone. You should replace the battery as soon as possible.
It starts because current flows easier in a warm battery. But any guessing about what the problem is needs to start with a charged battery, lead acid batteries need to be charged to 12.6v, if it won't charge to 12.6v, the battery needs replacing. It also sounds like your charging system may not be working right, which may have caused the battery to fail. With a charged battery check voltage at battery at 2500-3500rpm, it should read 13 to 14 volts, most bikes do not charge at idle.
The Chevy volt car is an electric car but not fully because the battery only goes for 25-50 miles per charge. After that, a gasoline engine starts and produces energy for the electric battery to run the car. Gas is only used after the battery is run down and can be charged again.
Yes you can leave your laptop charger on once the battery is fully charged. however, modern Li-Ion batteries should never be run ar full capacity continuously. We recommend either removing the battery if you plan on using your laptop for a long period of time on the mains, or let the battery run down once a week and then recharge it again to keep the molecules moving within the battery. See our simple guide here on how to care for your laptop battery
Its likely either the battery connections (terminals) are dirty, or where they connect is...or the battery while showing a charge is bad when on a load. If it starts with a jump from another car...it's the battery.
When the alternator starts charging the battery voltage will increase about two volts to charge the battery.
You either have corroded battery terminals (where cables hook on battery)or a bad alternator ...Autozone willtest for free
Because the alternator keeps the battery charged when the car is running.
