8 volt battery for the old CASE

I have CASE SC and DC. Seems like 6volt batteries are not as good as use to be. (I keep a little trickle charger on them at times) The antiques sit a lot, but seems like they need a little more "umph" when it comes to cranking. Can I put in an 8 volt Battery? Will it effect the electrical parts---the generator, voltage regulator, ignition, lights....?

I agree with Randy in Nebra. If your tractor is in a good tuned up condition you only need a 6 volt. Don't matter if it old or new style. What are you going to do in a couple of years when 8 volt isn't enough? Go to 12 volt?

As the late Hugh MacKay was fond of saying: These tractors were designed to start on 6v and if properly maintained they perform as designed. One of the most important things is to have a heavy duty 6v cable. Do not try using a 12v cable. The 12v does not have as many wires as the 6v does. Power = current x voltage. If the voltage is 1/2 then the amps is going to be twice as much. Hugh always recommended using 0 or 00 gauge wires. I have had a 6v battery in one of my C's for at least 4 years. It doesn't get used much but enough to keep the battery charged. No problem spinning the starter. I am not saying anything against converting to 8v. You may have to replace the light bulbs with 12v bulbs. A friend did this on his Super H and the first time that he turned the lights on they blew. Each system is a little different. The manufacture of batteries is different for different classes of batteries. Sometimes a cheaper battery is exactly what you get, not always. Many factors involved.

Well if you can find an old 6 volt battery from the 1960s and remove the top and compare it to a 6 volt battery of today. You will find that the battery of today is a plate or two less than years ago. Yes, you can use an 8 volt and it will work much better and crank it over. The charging system will work since it olny has a cut out on the generator and the lights will also work. I run 20 tractors on 6 volt systems during harvest and I have special orderd 6 volt batterys with the full amount of plates in the past. The manufacture would not do it the last few years because the batterys with the full amount of plates lasted 6 years!
