i think i remember that i could use a 12 volt charger to charge a 6 volt battery if the lights weren't on, is this correct?
thanks

Depends on the charger. Google your question, you will get technical answers to your question.
 
If it's like most chargers it will shut itself down if you try to charge a 6V batt with 12V. Otherwise it will burn up, maybe you with it.
 
Good afternoon...If you can drive your Model A as little as 10 miles a week, you will not need a charger and your fuel will stay fresh with just a bit of Marvel Mystery Oil added to your fuel...All a Model A asks is to be loved and used. Ernie in Arizona
 
Yes, you can charge a 6 volt battery safely on a 12 volt charger, but ONLY if you use correct resistance in series with the charger leads. Use a 12 volt light bulb in series, and it will safely charge the battery. Use a tail light bulb for low charge, or a headlight bulb for a higher charge rate.


I only use a 6/12 charger with a volt meter with numbers. I use my old Sears charger the most. It's rated 6 amps, has a volt meter with numbers, and a 6/12 switch.
 
When I was a kid I worked at a service station, and we worked on tons of cars, towing too. If you ever saw a battery bow up you would never even consider such a thing.

If a battery has just a little charge, just get a couple neighbors, and push start the thing.
 
Many of the older battery chargers did not have a fuse. The transformer windings were the "fuse" and would burn up if a short occurred or hooked up in the wrong way.(6 or 12 volt). Some had a cheapo circuit breaker that I wouldn't trust either. DON'T leave those type chargers unattended.
