What to Consider When Selecting the Best Battery Powered Backpack Sprayer

What is the primary use of your sprayer?

If you are using mainly oil-based carriers or for woody plant control or pest control, you will need sprayer pumps, hoses, and oil-resistant seals.

The best electric backpack sprayers must have durability for long-lasting use, especially with multiple applicators using the same equipment.

Battery life

The battery life of a electric backpack sprayer will determine how long you can use the sprayer with just one single charge.

Some brands have a battery that can last up to ten hours with one single charge. Some other brands can last less than that.

Type of pump

An electric backpack sprayer will come with a diaphragm pump or a piston pump. The piston pump is lower in price than diaphragm pumps.

Piston pumps may not be suitable for liquid herbicides or weed killer chemicals or pesticides (pest control). If you are applying desiccant herbicide or weed killer chemicals or pesticides (pest control), the piston pump may wear out faster and need replacement.

A diaphragm pump will offer ease of repair and durability with herbicides for long-lasting use.

Safety and comfort

Features like a spray wand grip and a full-size pump handle help reduce any fatigue. A contoured tank and an adjustable, chemical resistant padded straps deliver a comfortable fit for the user.

A padded harness has to be bought separately for some brands. Find viton type rubber seals that resist softening and swelling that can cause leakage and pump breakdown.

Spray wand

A high-quality spray wand can withstand any factors that may cause leaks and can deliver accurate application and comfort to the user.

Find the best electric backpack sprayers with wands that accept the TeeJet caps and nozzles, that let the user choose from a numerous assortment of industrial-grade tips. The spray wand can determine the spray patterns.

Ease of repair and has durability

The tank should be made of high-density polyethylene with UV protection for you to have a quality tank.

Seals, other accessories, and hoses should be rated for additives and herbicides.

Repair parts for your electric backpack sprayer should be available online or at your local suppliers to replace components such as pumps.

How to maintain an electric backpack sprayer?

To ensure to achieve a long-lasting sprayer, cleaning after every use is very important to the sprayer.

Once you do a routine cleaning of it completely at the end of the day with a tank cleaner or just clean water, you will sure it will last longer.

Do the lubrication of the o-rings and at least one time in one year. During the colder months, you need to add RV antifreeze or automotive antifreeze to prevent any damage due to cold temperatures.

It is recommended to use automotive antifreeze because it is less corrosive to spray equipment pumps. Charge the battery after every operation. This practice will help prolong the life of the battery.

Remove the battery from the best electric backpack sprayer and place it in a dry location away from pets and children.

When storing the battery for a long time, make sure the battery is around ½ charge. Always store the battery in a dry place. The battery should be changed every one to three months to ensure the long life of the battery.
