Batteries do not last for ever and after about 3 years they need to be replaced. An old battery simply will not hold its charge. Therefore as a first step in chasing down your problem, get your battery tested.
Yes.
Dead cell in the battery or something is on pulling power from the battery. If it is a dead cell the battery must be replaced.

Could be the switch between the front seats, or a fuse, or a shortcircuit in the wire with power from the battery.
Yes, a dead cell in the battery or something is on drawing power from the battery.
Either the battery is defective and has a dead cell or something is on which is pulling power from the battery every night.
The old battery was bad it could cause a power surge and plow the main fuse.
Two things come to mind: 1 - your new battery could be bad; 2 - you have a wiring problem. You may have a short somewhere that is pulling down the battery. Also, check the battery post connectors where they are fitted onto the wire. Something loose there can cause you grief, too.
Dead cell in the battery requiring a new battery. A light that is on pulling power from the battery. Relay stuck in the closed position. More than likely the battery has a dead cell.
Cars don't turn off completely, they run on battery power. The headlight switch needs to be turned off.
If you have no battery then you have no power.
