Choosing a replacement battery
Fit and electrical rating both matter
Match voltage, case dimensions, terminal layout and hold-down first. Keep the replacement at 12 V, but verify CCA/Ah from the tractor's battery label or service manual because the exact rating was not confirmed here.
1. Voltage
Use the verified system voltage shown above.
2. Physical fit
Match battery tray dimensions, height and hold-down style.
3. Terminals
Confirm positive/negative terminal positions before buying.
4. Starting power
Meet or exceed published CCA when a confirmed CCA is available.
5. Multiple batteries
When the tractor uses two batteries, replace weak/mismatched pairs thoughtfully and confirm the factory cable arrangement.

What does the Case IH Farmall 35A 70 A alternator mean?
Quick answer
The charging system is rated at 70 A. That figure tells you the system’s maximum charging/accessory output, not the current constantly forced into the battery.
