Use a volt ohm meter and set it on DC voltage. Put the red (+) on the positive and the black (-) on negative.
Yes, if you have a 12 V solar battery charger.
12 volts in a car battery
With any 12 volt battery charger.
12 volt battery in a car
hook wires from your 12 v battery straight to the fan motor and see if it comes on.
No.
As w = v * a current = 150 * v * a / (12 * v) = 150/12 * v * a / v = 150/12 * a = 12.5 * a = 12.5a
By the number of cells. A 12 V battery should consist of 6 cells, each providing about 2 volts. A 12 V battery should consist of 6 cells.
A fully charged battery will show 12.6 volts if the car is not running. If it's running it will show between 13.5 & 15.5 volts. You will need a digital DC volt meter to test it. A reading of 12.4 V indicates the battery is at 75% charge 12.2 volts and it is at 50% charge 12 V indicates it is at 25% charge.
its 12 v
With a 12 V battery and two jumper wires. One prong is ground and the other two are high and low beam.
Usually one that can maintain the voltage at 12 V so that it can safely charge a 12 V battery.
