What to consider when selecting battery powered backpack sprayers
Primary use
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.
Battery-powered backpack sprayers must have durability for long lasting use, especially with multiple applicators using the same equipment.
The manual or battery-powered
Manual sprayers are usually for treating new infestations or for pest controil.
A battery-powered sprayer will provide more convenience for large areas. The battery-powered sprayer will ease off the pressure from manual pump to maintain pressure.
But, these sprayers are commonly more expensive, heavier, and need more maintenance compared to manual sprayers.
If you decide to purchase a battery-powered sprayer, the battery must handle both high and low sprayer psi output.
Battery life
The battery life of a battery-powered 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
A battery 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.
Safe 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 spray 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 should be available online or at your local suppliers to replace components such as pumps.

Overall score
Our tips
Our finding is that a few reviewers said that they have the right tools and materials to do the spraying job. Through their experience, this battery-powered backpack sprayer does the job well, and when they test spray with water to check for leaks it went well.
They would not use a hand pump sprayer because the sprayer can hurt the back and hand by re-pumping far too often. Reading its feature we can say that this Chapin battery-powered backpack sprayer is very quiet during the spraying.
Many reviewers also mentioned the 20v battery that still stayed strong after a 45 minutes spraying. If you are having back issues, we recommend filling the tank with only two or three gallons on the full property spray. We would say that this amount is the right balance of weight for lower back issues.
Looking at its weight and size, we can say that the unit is rather bulky. You need to use a table to fill up the sprayer. This method is much easier compared to lugging it off the ground.
According to its manual, it has a nice volume of spray per trigger pull or you can hold down the trigger for continuous spray. You can adjust the nozzle when the pump speeding up or slowing down.

How to maintain battery-powered backpack sprayers?
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 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.
