I need to get a new battery for a 48 A. The A uses two 6 volt batteries in series. I read in the archives where a single 12 volt is just as good as the two 6 volts. I plan on getting an Interstate battery. Can anyone help me understand the difference putting in two 6's vs one 12. Are there advantages/disadvantages? Which Interstate battery would be the best to get?

Mike I have a '51 A with one 12V battery and I had no trouble starting with it even after a fresh rebild on the engine. I also like fewer connections and less upkeep. The two 6V batteries will probably cost more than a decent mid-grade 12V. Just my opinion. Good luck with your A and whatever you decide!

Mike, in the early days when batteries were not a sophisticated as they are now it took 2- 6 volt batteries to get enough plate area to get an amp hour rating [C.C.A. wasn't used then] high enough to crank the engine in cold weather.
~Today's modern batteries with the ultra thin cases, larger thin plates & better technology will allow 1 semi cheap 12 volt battery to run circles around 2 of those old 6 volters. ~The only problem [& it really isn't a big deal] is the modern 12 volt sealed car battery is designed to be charged at about 14.2 volts & the old tractor regulators were set up to charge in the high 13 volt range so the battery doesn't always get to a full charged state.
~One advantage to the single sealed 12 volt battery is you don't have to add water & if you have a nice show tractor have less chance of acid boiling out & ruining your nice paint.
~Bottom line: your choice on whether to use 1-12 volter or the original 2-6 volt set up....

Mike, With 2-6v you are more original, w/1-12v you will have 2 less connections to corrode. The modern 12v battery has plenty to wind up an old A. gwh
