  • ALL N-Series and up thru the Hundred Series Ford Tractors used a 6-volt battery, rated as a Group 1 type; 80 amps capacity; and 39 plates, that's 13 plates per cell. Th e original Ford Tractor Operator's Manuals states to check electrolyte level at least twice monthly and to keep battery fully charged. The specific gravity of the electrolyte indicates the amount of battery charge. For example, from the 600/800 manual chart:

    Fully Charged, specific gravity level in a temperate climate = 1.280
    Fully Charged, specific gravity level in a tropical climate = 1.225

    Levels decrease as battery charge percentage decreases.

    Hope this helps...LINK below to our MANUALS forum for a 1953 Dearborn Accessory Catalog -look on page 13...

  • don't know the answer to your question exactly but I saw a reference to an 80 amp hour battery for the 6 volt for these tractors in some of my literature, for whatever that is worth.

    I might be way off but I would guess the last 6 volt I put in my 8N was somewhere around 550 to 580 cca. I think you can buy better, that is just what I found in a local parts house.

  • There was no CCA battery rating in 1953.

  • I would buy the highest capacity available in the correct size.
