old and cold = bad battery
The function of a battery is to provide electrical energy to devices which are connected to it.
Jump-starting a friend's car shares your car's battery's electrical charge.
The battery.
The Battery, if you are meaning electrical charge in a laptop?
There is a good chance that your alternator has stopped working. It could also be just a loose wire from the alternator to the battery that is not letting the battery charge. Also it could be a bad battery. When a cell in a battery dies it will hold a charge for a short period of time but then rapidly die. Get the battery checked first. they the wires, then the alternator.
No, the alternator will not charge the battery with the negative terminal loose.
No, a battery cannot recharge itself. The alternator converts some of the engine's energy into electrical energy which is then stored in the battery. If a battery is not getting recharged under normal driving conditions, you either have a problem with the charging system or a failed battery. You can't know without testing. On the other hand, sometimes a dead battery can get what's called a "surface charge". A surface charge just means that when you were cranking last time, you depleated all of the readily available electrical charge. By letting the battery sit for a while, "entropy" has allowed some of the chemical reaction to spread out over all of the battery plates... but the battery cannot "create" electrical energy.
None. What the battery stores is chemical energy. It creates electrical flow by converting chemicals from one form to another.
Wood will not accept any kind of electrical charge.
For the positive and negative charge that flow through the electrical charge
The battery in your car does not constantly charge while driving. Electricity is needed to run the headlights, starter, radio, etc. In order to save wear on the alternator/generator, the battery is sometimes used to power these electrical devices as your car's internal sensors see fit. When the battery's charge drops below a certain voltage, the alternator kicks in again to keep the battery at its optimum level.
A battery works by converting chemical energy into an electrical charge. Electrolytes let ions move between the positive terminal and the negative terminal, which makes the electrical current flow.
