Most backhoes use standard 12V batteries, but choosing the right type and configuration is critical for reliable cold starts and long-term durability.
Backhoe Electrical System Overview
Backhoes like the New Holland LB75.B or John Deere 5103 are equipped with diesel engines that require high cranking amperage, especially in cold weather. These machines often sit idle for weeks, and their batteries must deliver enough power to overcome cold oil viscosity and compression resistance. While some models use two smaller batteries in parallel, others rely on a single high-capacity unit.
Terminology Note
Factory batteries from equipment dealers can cost over $250 each, while equivalent units from auto parts stores or battery specialists may be under $100. However, not all savings are equal:
Maintenance Tips for Seasonal Use
Backhoes do not require proprietary batteries, but they do need high-performance units with sufficient CCA and durability. Whether using dual batteries or a single Group 31, the key is matching electrical demand with climate and usage patterns. With smart selection and regular maintenance, even budget-friendly batteries can deliver dependable starts and long service life.

Terminology Note
- CCA (Cold Cranking Amps): The amount of current a battery can deliver at 0°F for 30 seconds while maintaining at least 7.2 volts.
- Group Size: Battery dimensions and terminal configuration standardized by BCI (Battery Council International).
- AGM (Absorbent Glass Mat): A sealed battery type with better vibration resistance and lower self-discharge.
- Trickle Charger: A low-current charger that maintains battery voltage during long idle periods.
- Dry Cell: Often used interchangeably with AGM, though technically different in chemistry.
- Match or exceed OEM CCA ratings. For example, replacing two 750 CCA batteries with a single Group 31 battery rated at 1100 CCA is viable in moderate climates.
- Consider AGM or dry cell batteries for machines exposed to vibration or extreme temperatures. These offer better cold-start performance and longer life.
- Check physical fit. Some aftermarket batteries may not align with tie-down bars or terminal recesses, especially in New Holland models.
- Avoid underpowered car batteries, even if they appear similar. Backhoes demand higher cranking power and deeper cycling capacity.
Factory batteries from equipment dealers can cost over $250 each, while equivalent units from auto parts stores or battery specialists may be under $100. However, not all savings are equal:
- OEM batteries often include features like recessed terminals and custom tie-down compatibility.
- Aftermarket batteries may require minor modifications to the battery box or terminal connectors.
- AGM batteries can cost $200 or more but offer superior performance in cold climates and long idle periods.
Maintenance Tips for Seasonal Use
- Use a solar-powered trickle charger if the machine sits idle outdoors.
- Start the engine monthly to circulate oil through the turbocharger and prevent seal drying.
- Inspect battery terminals for corrosion and clean with baking soda solution.
- Replace batteries every 3–4 years, even if they still hold charge, to avoid sudden failure during critical use.
