The alternator - it provides a charge to the battery while the engine is running.
I usually leave it plugged in if I can, because why not keep your battery charged?
No, after the battery in your laptop is fully charged the power is cut off to it.
It is there to keep the battery fully charged.
Keep it charged and it will not freeze. A 1 amp trickle charger works well on a stored battery in the winter.
the same way a car
It has to be 13 plus volts to keep the battery charged. The car requires a 12 volt battery to start and run this vehicle, so you need more then 12 volts to keep the battery charged.
I would drive it at least enough to keep the battery charged. The battery can actually fail just from not being charged.
As long as you keep them charged you do not have to remove them. A fully charged battery will not freeze, but a dead battery will.
An alternator has diodes which transform ac voltage to dc voltage so that the battery gets negative and positive current on its poles thus making the battery to be charged.
Yes, this will prevent the clock from running it down. You can also install a trickle charger to keep it charged. A battery with no charge will freeze. Keep it charged and it will not freeze.
No, not if the battery is fully charged.
