Disconnect the battery cable, you do not have to touch the battery.
Airplanes do it all the time.
To store electrical energy.
Yes, they most certainly do. Without a battery that would be nothing to store the electrical energy. Without the electrical energy you would not even be able to start the engine let alone drive the car. The battery supplies electrical power to all electric components within the vehicle. Without a battery the car is just a hunk of metal that is going nowhere.
The alternator is probably bad. That is what recharges your battery
Trailer batteries are not meant to power things all night long without being recharged. Leaving a light on or the refrigerator on without backup power will drain a battery overnight or sooner. Either use shore power or in the case of the refrigerator, switch to the gas mode if available. The battery also may have a bad cell that won't let it charge fully.
its main use to drive the alternator that powers your battery and other electrical components it also runs the air conditioner compressor, without it your car battery will drain all its power and you'll eventually lose power your car stops moving.
yes you can but it is bad for it even if you use a dead battery it is better than no battery at all
yes because god gave you power to do it all. get all that rubish out of yore head and and be focest
The power of a d size battery is usually 13A but it all depends upon the chemistry of battery but these batteries are usually made to support small physical devices.
