The charger needs to be set to charge for the voltage that the battery is designed to produce. Most car batteries are 12 volt batteries.
well it kinda says in the name TWELVE volt battery so it kinda takes TWELVE volts to work correctly
A twelve volt charger will charge twelve volt batteries only unless it has a feature that allows you to change the chargers voltage. But on fast or slow charge 12 volts is 12 volts so most 12 volt chargers are only good for 12 volt batteries.
Yes, you can use a twelve volt car battery charger. Be sure to set it on low.
Use the next higher scale than the voltage you are trying to read. It should be either 20 or 30 volt DC
It varies widely from around 300 on a small car to over 1000 on a truck battery.
You do not charge a 7.2 volt battery with a 9.6 volt charger period unless you want to ruin the battery. You charge it with a 7.2 volt charger.
They must be wired in series. Use only heavy battery cable. Connect Neg.pole on Batt,A to Pos. pole batt B. Between Pos. pole Batt. A and Neg. pole Batt. B you should have 24V.
Should be a 12 volt battery.
connect the 2 six-volt batteries together one terminal each positive to negitive, this will make a 12-volt combination, then you can connect the jumper cables, one side to the 12-volt battery and one side to the two 6-volt terminals, + & -
you put the negative side to the positive side, and tape them stuck Hook them up "in series", like a flashlight. Connect the positive (+) of one battery to the Negative (-) of the other, then use the unconnected leads of each battery as the posts of the 24 volt battery.
connect the power and acc wires together and put them on the positive and the ground to the negative
Take 3 twelve volt batteries Run the + of battery #1 to the - of battery #2. Run the + of battery #2 to the - of battery #3. Use the + of battery #3 for your positive feed, and the - of battery #1 for your ground.
