It's called static electricity. The 12 volt system in cars and trucks are not enough to shock someone. Even 24 volt systems found in buses and heavy trucks are not enough to feel. So it has to be static electricity somehow.
0.5 amps
No, since in series they are 24 volts so you need to charge each one independently with the 12 volt charger. This may be done disconnected or leave them connected and put the charger on the + - of the same battery.
To get 24V from 2 12 V battery's Yo hook up the positive pole + of one of the battery's to the negative pole - of the other one. you will be left with a positive pole on each battery wit no connection on them The voltage between them is 24. If you want the battery to have the same voltage but have more amperage you connect positive to positive and negative to negative.
No
Most cars use a 12 volt system. Most cars built before about 1956 used a 6 volt system. Some, very few, use a 24 volt system.
No.
use two 12 volt batteries in series.
the ford is a 12 volt system it has 2 batteries to help in starting . but it is a 12 volt system
Hook a 12 volt light to a 24 volt system and the light will burn out in seconds. You need a step-down voltage converter to do this.
no
Separate the 2 12 volt batteries and charge them individually.
Use a voltage devider or a transformer.
can 6 ,12 volt battery be wire to make in to one 24 volt battery for solar use in home
Small pick up trucks use a 12 volt system. Large highway trucks use a 24 and sometimes 36 volt system, depending on the lighting load that is connected.
You only need 2 12 volt batteries to get 24 volts. Join the negative post on one battery to the positive post on the other battery with a cable then connect the remaining positive and negative posts to the vehicle that has a 24 volt system.
