If it is a 12 volt marine battery, then yes. If it's a 6 volt marine battery, then you would need two of them wired in series to make the 12 volts needed to start the vehicle.
It is 12 volts.
The battery voltage on a PT Cruiser is typically 12 volts.
12 volts
Motorcycle batteries may be 6 volt rather than 12 (check this) and if they are 6 volts, switch your battery charger to 6 volts or you may damage the battery.
It is 12 volts.
12V.
Automobile batteries today are all 12 volt. Most auto manufacutures switched from 6 volts to 12 volts in the 50s.
Modern automobile batteries are 12 volts.
for the relay switch 6volts, for the battery... dunno- mine's a 250 and uses an ATV battery.. I think they're 12 volts.
That is Impossible. You can however make two 6 volt batteries into a 12 volt system by wiring the two 6 volts batteries in Series. You will then have an output voltage of 12 volts but the amperes will only be what one of the batteries have, In other words the volts will double but the amps will stay the same as if you only had 1 battery connected.
12 Volts 18 amps
