Gear shifting has little to do with batteries, or your car's electrical system. If your car is stuck in one gear, your clutch (on a manual) or even worse, your transmission, might be going out. The dead battery might be just a coincidence.
A storm has nothing to do with the battery going dead.
No, this will place a very heavy load on the alternator of the car and may result in burning out the diodes of the car charging the battery. You could easily ruin the alternator. Purchase a battery charger and charge the dead battery with that. Alternators are not made to charge dead batteries.
Get a donor car and use it's battery to start your car. You will need a set of quality jumper cables. Or you can charge the dead battery on the car for about 2 hours with a good 10 amp battery charger.
A completely dead battery or a bad connection to the battery.
Jump the car from another car battery or hook a charger to the battery.
Dead battery, jammed starter rotor arm - it it's manual, put it in gear and then rock the car back and forth to un-stick the rotor arm. If it's the battery, main lights will be dim or not work.
Your car won't turn on.

If it has a dead cell the battery will not hold a charge and must be replaced.
Some car battery charges will not charge a completely dead battery. You need to find a type of battery charger that is designed to charge a completely dead battery. You can get around this by hooking a car with a working battery up to the dead battery with jumper cables. The alternator/charging system of the car with the good battery will charge the dead battery. Leave them connected for about 30 min, then disconnect and try to use the battery charger again. If it still won't charge, hook it up to the car with the good battery for a longer period of time.
if anything is running off the battery (visibly on) the battery will eventually go dead
A dead battery will have no effect on the computer in the car any more than unplugging your home computer.
