Why do large tractors and combines use a 24V bank with two batteries?

Because a large-displacement diesel engine needs more cranking power than a single 12V battery can deliver. The two batteries in the bank are wired in series and must always be replaced together, never separately.

How long does a battery last on a tractor used intensively at harvest?

It depends on the number of starts, engine hours and off-season care; 12-16 hour days running hydraulics and cab air conditioning demand more from the battery than occasional home use.

What's the difference between SHD and EFB in a tractor battery?

SHD (Super Heavy Duty) reinforces the internal grids to withstand vibration and deep-discharge cycles typical of fieldwork, while EFB (Enhanced Flooded Battery) is used in modern tractors with more engine stop-start events and onboard electronics.

How to choose the right tractor battery

A farm tractor cranks a 4-12 litre diesel after weeks or months of off-season idleness and then works 12-16 hour days during harvest. The battery must tolerate cranking after long idle (very low self-discharge) and heavy daily use with hydraulics, cabin AC and auxiliary lights.

Typical capacities

Type	Capacity	CCA	Technology
Compact tractor <60 hp	95-110 Ah	720-850 A	SHD / EFB
Mid tractor 60-150 hp	140-180 Ah	900-1,000 A	SHD
Large tractor 150-250 hp	180-225 Ah	1,000-1,150 A	SHD
Combine / harvester	180-220 Ah (24 V bank)	1,000-1,150 A	SHD

Combines and large tractors run a 24 V bank with two 12 V batteries in series: replace both at the same time.

Compatibility and how to choose correctly

Always check capacity (Ah), CCA and whether your tractor runs a 12 V or 24 V bank before buying. Find your model by make, engine and year in the comparison tool, or if your tractor carries a Spanish plate, use the plate finder to identify the original battery in seconds.
