No chargers usually produce about 1.5 volts above the battery to be charged. By connecting a 12 volt charger to an eight volt battery it will boil the electrolyte in the battery.
No, an automobile battery charger outputs 12 Volts. This is far too many volts to charge a 5 Volt battery. You would destroy the 5 Volt battery with this charger.
No, you cannot charge an 8 volt battery with a 6 volt charger. The voltage of the charger must match the voltage of the 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.
Yes. A battery draws what it needs from the charger, the charger does not force current into the battery. The voltage spec. is the same. Things would be different if you were to try to charge a five volt battery with a ten volt charger. You would probably blow the battery. Hope this helps.
No, the battery charger has to match the voltage of the battery it is to charge.
No, a 12 volt charger will overcharge a 8 volt battery and destroy it.
A .6 amp charger is a trickle charger. It would take days to charge a dead 12 volt battery with this charger. You need a 10 amp charger which will charge it in a couple of hours.
No.
Charge it with a 12 volt battery charger.
If you are asking the question, can you charge a 6 volt battery with a 12 volt charger, the answer is no.
You would need a 24 volt charger. Connect them in parallel and you can charge them both with a 12 volt charger. Or disconnect them and charge each one separately.
A 12 volt battery charger is designed to charge 12 volt batteries.The answer to the Related Question explains how any battery charger works.
