The old school way was two 6 volt batteries in series. Then later model tractors switched to 12 volts batteries in parallel. Years ago I was always told that the two 6 volt batteries would give you more CCA. Lately I have been told the opposite, that two 12 volts will give you more CCA.
So in layman terms (old fart understandable ) which is better and why???
The reason I am asking I just switched one of my JD 4450s over to the two 12 volt batteries for two 6 volts. My reason is I can buy the 12 volt batteries much cheaper and they seem to last better than the 6 volt ones. The tractor cranks better but that could be because of new batteries and good cables/conenctions too.
