Seesii 5 Gal Leak-Proof Battery Backpack Sprayer with Dual Batteries, 100 PSI Pump

The SEESII 5 Gal Leak-Proof Backpack Sprayer is a battery-powered garden sprayer with a one-piece 5-gallon tank, two rechargeable batteries, a 100 PSI pump and seven interchangeable nozzles for extended, hands-free outdoor spraying.

This electric backpack sprayer is designed to make large-area lawn, garden and orchard applications faster and less tiring. Its blow-molded, seamless tank reduces the risk of leaks, while dual 2.0Ah batteries extend runtime without manual pumping. Adjustable pressure and a telescopic brass wand let you switch between fine misting and focused streams so you can treat weeds, fertilize, water plants or clean outdoor surfaces with control.

How long will the dual batteries keep me spraying?

The sprayer ships with two 2.0Ah rechargeable batteries and a single charger. Each battery delivers up to about 1 hour and 48 minutes of continuous operation at typical settings; swapping packs gives roughly 3.6 hours of total runtime without manual pumping.

• Includes two 2.0Ah batteries and one charger
• Single-battery runtime ≈ 1 hour 48 minutes
• Combined runtime up to ≈ 3.6 hours with battery swap
• Battery-powered pump removes need for hand pumping

What spray patterns and pressure control are available?

You can vary output from a gentle mist to a concentrated stream thanks to the adjustable electric pump that reaches up to 100 PSI. The kit includes seven nozzles—fan, cone and shower styles—to match tasks from broad coverage to precision spot treatments.

• Adjustable pressure from 0 to 100 PSI for flexible application
• Seven interchangeable nozzles for misting, showering or targeted spray
• Telescopic brass wand for extended reach and durability
• Use settings for weed control, fertilizing, watering, or cleaning

Is the sprayer comfortable and leak-resistant for large jobs?

The tank is blow-molded as a single piece to eliminate glued seams and weak bottoms, helping keep the battery compartment and your back dry. Thick, breathable padded shoulder straps distribute weight so carrying a full 5-gallon load is easier on longer chores.

• One-piece 5-gallon tank reduces leak points
• Padded, breathable shoulder straps for comfort over time
• Large capacity means fewer refill stops on big properties
• Battery compartment design protects electronics from spills
