Top 7 best electric agricultural sprayers in 2025

What is an electric agricultural sprayer?

An electric agricultural sprayer uses a battery or accumulator to power the pump, creating pressure that pushes the pesticide solution through the nozzles. Compared to manual or gasoline types, it reduces labor intensity, minimizes chemical exposure, and emits less pollution. In large-scale farming, it can also be paired with agricultural drones to enhance productivity and spraying coverage.

Operating principle

• Electric pump: The most common type, using piston or diaphragm pumps.
• Air blower system: Less common, creates an air stream to atomize the liquid into fine mist.

Why choose an electric sprayer over a gasoline sprayer?

Electric sprayers are preferred for their low noise, cheap operating cost, easy start-up, and enhanced safety. Gasoline sprayers, however, are more suitable for very large areas due to their mechanical durability. For small farms, a 20L dual-pump electric sprayer is an ideal choice. Larger farms may combine these with agricultural spraying drones to increase coverage efficiency across hectares.

Key factors when evaluating electric sprayers

• Tank capacity: Usually 16–20 liters, ideal for vegetable gardens or fruit orchards.
• Battery power: 12V–8Ah for small gardens; 12V–12Ah or Li-ion batteries for extended shifts.
• Pressure and flow rate: At least 100 PSI and ≥7 L/min for dense canopy coverage.
• Weight and ergonomics: Lightweight, with padded straps for comfort.
• Warranty and parts: Easy to find replacements and technical support.

Safety tips for using electric agricultural sprayers

• Wear full protective gear: Long-sleeve clothing, specialized mask, and rubber gloves to minimize chemical absorption.
• Inspect wiring and nozzles: Ensure no leaks and clean nozzle tips for uniform spraying.
• Spray with the wind direction: Never spray against the wind to avoid back-drift and inhalation.
• Clean tank and nozzle after each use: Flush remaining solution, rinse with clean water to prevent buildup.
• Recharge batteries properly: Avoid full depletion or overcharging. For Li-ion, recharge at 20–30% remaining capacity.
• Store in a cool, dry place: Avoid direct sunlight and heat, and periodically check screws and safety valves.

Following these steps not only keeps your electric agricultural sprayer working efficiently but also protects user health and the environment.

Maintenance checklist

Daily (after each use):

• Empty leftover liquid to avoid clogging.
• Rinse tank, hoses, and nozzle with clean water.
• Wipe machine dry, avoid moisture near the battery.
• Check straps and padding for tears.

Weekly:

• Inspect nozzle head, filters, and check valves.
• Tighten screws and electrical connections.
• Compare spray time with original specs to detect efficiency loss.
• Recharge maintenance once per week even if unused (for lead-acid).

Monthly:

• Check battery voltage and signs of wear or leakage.
• Lubricate joints and friction points.
• Test maximum PSI output for consistency.
• Take to an authorized service center if abnormal noise or leaks occur.

Routine maintenance can extend lifespan by 1–2 years, reduce repair costs, and ensure accurate spraying dosage.

Conclusion

These electric agricultural sprayers meet diverse needs—from small households to medium farms. Choosing the right model based on area size, spraying duration, and battery type will help optimize cost, improve crop protection, and minimize health risks.

FAQs

Is a 20L sprayer too heavy to use?

When full, it weighs around 25–28 kg. You can split spraying sessions or use a trolley to ease the load.

Is a Li-ion battery better than a lead-acid one?

Yes. Li-ion batteries are lighter, charge faster, and last longer per cycle, but they’re more expensive.

Should I choose a single or dual pump?

Dual pumps provide stronger pressure and higher flow, ideal for large areas. Single pumps are more economical for small gardens.

How often should I replace the battery?

Lead-acid: every 12–18 months; Li-ion: 2–3 years with proper charging.

Should I buy online or from a dealer?

Online shopping makes price comparison easy, while local dealers offer better warranty and support. Ideally, choose a trusted supplier with a clear return policy.
