Some replies to Rich Barber's comments: I have also use 12 volts to crank one, but always worry about the starter relay on the fender. These things are really getting difficult to find. As far as batteries I always try to use the Optima 6 volt. These are strange looking, but through the Packard International Club http://www.packardsinternational.com/ you can purchase a battery box that looks pretty much like an original tar top 6 volt battery. There are two versions they offer and I think the more correct looking one is about $75.00. The Optima fits in on a diagonal and the top comes off and on for access. The only change is the terminal locations are reversed, thus you need a little longer ground cable. The 12 volt Optima batteries are available at Costco here in the USA for about $100. I've never seen a 6 volt example there as it is a much smaller market. For years I've used nothing but Optima's in our collector cars with great results. I've heard the stories about the 8 volt systems, but understand there are issues with certain components on our Chryslers in doing this. Last, Rich I would recommend you carry some starter fluid rather than gasoline. Much less chance of an accident and you can get a nice high while cranking with the stuff !!

I jump started many 6-Volt cars with 12-Volt batteries back in the Midwest winter 50's when the 12-Volt battery Voltage was probably lower due to the cold weather. I have jump started mine with 12-Volts, but feel this could be damaging to the ignition and/or charging system. I also recall some cars like the big old straight-eight Packards had 8-Volt systems. The 6-Volt light bulbs usually were rated at 6-8 Volts and I imagine the few accessories on a C-300 would work just fine on 8 Volts. The radio and fuel gauge are questionable. Whether the generator and Voltage regulator could be set up to keep the battery charged is beyond my expertise or memory, but seems it could be done. I do keep a second full-charged 6-Volt battery in the trunk for emergencies. I'm sure you have seen all the electrical tips for our C-300's, but to review: Positive and negative cables size to be proper and connections corrosion free. Voltage regulator and/or trickle charger set to keep a full charge on the system. Perhaps a multi-viscosity oil for cold Swedish climate. I have found a Group 2 battery that has some extra power. It is a Workaholic (By Interstate Batteries) Group 2XHD, 600 CCA, 750 CA. You might be able to find something similar at a boat or recreational vehicle dealer. If I can keep some gasoline in the carbs, the car starts well. I have not yet solved the incredible disappearing gasoline problem, but a hot block tends to evaporate the fuel from the glass bowls and carb bowls and requires removal of the air cleaner and priming the carbs with gasoline to get a hot start after sitting a while.

No doubt why they changed to 12V for '56. In pictures of other club members C300's I can see some have 8V batteries. Anybody having good experience from these? I have been looking for a 6V Jump Starter to have in the car as a backup when going on trips but I can not find any other than 12 or 24V. Is there someone out there who knows where to find one for 6 volt? Thanks!
