Why would you want a battery powered chemical sprayer?

Well, this is a pretty easy question if you have ever used a manual sprayer.  It is less work.  With manual sprayers, you have to constantly pump the sprayer to get the consistent spray volume and distance.  This is not an issue with battery powered chemical sprayers.  Battery powered chemical prayers make the task quicker and less taxing on the body.

I personally have a landscape that requires spraying fertilizers, insecticides, and herbicides several times a year.  Manual pump sprayers, either handheld or backpack style, take too long to work with.  With a battery powered sprayer, I can cover a lot of ground, garden, or home in a shorter amount of time.  This frees up more time to do other landscaping activities.

It is an important investment you are making, and we believe that you should have all the information you need before making the purchase decision.
