Battery Powered Backpack Sprayers – What’s the big deal?

Well, the big deal is time.  The one thing we can’t get any more of.  Now I don’t know about you, but spraying chemicals is not my favorite part of doing yard work.  It is a hassle, for the most part, so making it a quick as possible is the best thing to do.

Battery powered sprayers, in general, are just quicker chemical sprayers; they don’t require manual pumping to maintain the correct pressure and distance control which you have to do with either handheld or backpack manual sprayers.  The other plus for a backpack model is size.

Backpack sprayers are, in general, much larger than the handheld variety.  They have tank capacities of up to 4 gallons of liquid, which means fewer trips going back and filling up with more chemicals and water.  Fewer trips mean you can get the job done faster—Win-win in my book.

What features to look for in a battery powered backpack sprayer

When selecting your sprayer, there are a few things you should make sure the backpack model has. The powered backpack sprayer should have most of the following:

  • Multiple spray nozzles or an adjustable nozzle
  • Tank capacities between 1 gallon – 4 gallons
  • Comfortable shoulder straps or strap
  • See-through tanks to easily tell the number of chemicals in your chemical sprayer.
  • Long battery life
  • Removable or interchangeable tanks are a plus


Battery Powered Backpack Sprayers Frequently Asked Questions

What to consider when selecting battery powered backpack sprayers?

What do you do with your sprayer most of the time?

You need to consider what type of chemical you are going to be spraying.  Are you spraying just weeds, weeds, and insects, or are you applying a stain to a fence or deck?

You will also need to check out the durability of the materials for the backpack sprayer and how long you want the backpack sprayer to last.

Not all battery-powered backpack sprayers have removable batteries, so if you are concerned about spraying for long periods of time, you will want to look for removable and rechargeable batteries.

Another thing to consider is comfort.  What type of straps does the backpack sprayer have? Are they padded straps?  How adjustable are they?  Carrying around that kind of weight can be extremely tiring, so the correct kind and type of straps are important.

Why You Need A Battery Powered Backpack Sprayer?

The most common reason you might want a backpack sprayer is added spray capacity.  Most backpack sprayers hold around 4-gallons of liquid.  That much liquid will allow you to spray for quite a long time.

Another reason why you might want to purchase a battery powered backpack sprayer is comfort.  All sprayers over 1-gallon can become pretty heavy after carrying them around for even a short distance.  With shoulder straps, you can better distribute the weight and be less fatigued after a spraying session.

How to maintain battery-powered backpack sprayers?

Proper cleaning is truly the best way to keep your spraying year after year.

This means that you should clean the sprayer after each use.  Storing a sprayer with chemical residue inside the tank can cause clogged nozzles or clogged pumps.

I often let my sprayer air dry in the sun while I take care of other tasks so that the sprayer can be stored at the end of the day.

If you live in cooler climates, make sure there is no residual water in the sprayer’s parts.  If the water in those parts were to freeze, it might damage the sprayer.

Maintaining the battery in your battery powered backpack sprayer is essential.  Make sure the battery is charged and ready for use after each time you spray.  Always follow your manufactures recommendations for the care and maintenance of the battery in your sprayer.

What should I use to clean out my backpack sprayer?

The real simple answer is warm soapy water.  There are also specific sprayer cleaners, but warm water and a mild dishwashing detergent will get the job done.

Add water to the sprayer tank and let that sit for a while.  Pour that water out of the tank, and then add more warm water.  Run the sprayer to flush the sprayer’s pump and nozzles to keep them from gumming up from dried chemicals.

If your backpack sprayer has a filter or filter screen, make sure they are clean so the pump on the backpack sprayer can function correctly and efficiently.

Each of these products is capable of doing an excellent job.

While it was hard to pick a model that we felt was the best, we thought the Chapin Wide Mouth Battery-Powered Backpack Sprayer was the best battery powered backpack sprayer we tested.  This was a great all-around chemical sprayer with a large tank capacity with long runtimes from sprayer manufacture with a long history in lawn and garden sprayers.  This battery powered backpack model should handle all of the spraying needs of the average homeowner.

You can’t really go wrong with any of these models, however.  The only difference now is your personal preference and requirements specific to your plants’ care. Best of luck!
