Choosing a replacement battery
Electrical rating and physical fit both matter
Keep the replacement at 12V, but do not buy on voltage alone. Confirm the physical battery size, terminal layout, hold-down and starting rating from the original battery or operator's manual.
1. Voltage
Keep the replacement at the verified system voltage.
2. Case size
Match tray length, width, height and hold-down style.
3. Terminal layout
Make sure the positive and negative posts are on the correct sides for the tractor's cables.
4. Starting power
Meet or exceed the published CCA when a model-specific CCA is confirmed.
5. Capacity
Match Ah and reserve capacity when those ratings are published, especially on higher-accessory-load tractors.
