Its called a parasitic draw. Any electrical component in the vehicle could cause it. To test for a draw, pull the negative battery cable and use a meter to measure amperage between the battery terminal and cable. The reading should usually be below 50mA or <.050 amps.
one big horse power
It uses a little extra battery power, but not much.
Depends on Which horse is pulling ya
Yes, it can have a dead cell or something can be on pulling power from the battery. Batteries are just like people: Some live longer than others, but they all die eventually. A dead battery can indeed be an alternator problem, but is much more likely to just be a battery that reached the end of it's useful life.
There is a power icon on the taskbar. It shows whether the computer is plugged into the mains or on battery power. If you hover your cursor over the power icon, while it is running on battery power, it will show as a percentage how much battery life is left (along with an estimate of how much time you have left before the battery dies).

either a corroded or otherwise poor connection or the starter is pulling too much current
Your brain uses as much power as a ten watt battery. -Helen Brosnan
No. It does not require very much power. If the battery is not putting out enough power to turn the starter, but is putting out some power it may still work. If the battery is totally dead it will not work.
Sure. But not much water, a 9 volt battery has very little power (energy).

Usually the battery is weakening. When the weather is cold the battery has less reserve power and when it is warm it doesn't require so much cold cranking power. Usually the battery is weakening.
