Is it safe to use a 12 Volt Coil on a 6 Volt System?

When it comes to primary resistance, most standard ignition systems have a similar amount. The 6-volt system will support the 12 v battery as long as the ohms are matched accordingly.

If you're using a 12v pack, don't forget the ballast resistor. Also, turn off your radio and lights before installing them to protect points and coils from short circuits that could result in damage or even fires.

Can I use an 8 Volt Battery in a 6 Volt Car?

The 8-volt battery can be used for a 6-volt car, but you have to make adjustments. You should check if the cables are right and adjust your regulator accordingly. Startup the engine with full throttle, then disconnect it from power and verify that voltage reading is 9 volts or higher on an ammeter across two positive wires in one terminal of the battery and ground wire at another terminal--you'll need some screwdrivers handy.

It is possible to start a 6-volt car with a 12-volt battery?

If ever you wanted to start a 6-volt car with a 12-volt battery remember that by doing so is possible but there are some precautions that must be taken.

Will a 12-volt battery charge with the use of a 6-volt generator charger?

If you have a 6-volt generator and want to charge your 12-volt battery, don't worry. You can use some simple circuitry design with either diodes or cutouts but you'll need either an adapter or regulator for the voltage.


We hope that the guide and comparison above help you find the perfect 6-volt car battery for your needs and budget.
