About product

The HD3000 is the right pick for homeowners who need a reliable battery-powered sprayer for occasional yard maintenance without the size and cost of the larger PetraTools models. At 3 gallons, it is the lightest and most manageable option in the PetraTools lineup, and the 2-2.5 hours of runtime covers most residential jobs comfortably in a single charge. The same double-padded straps, 6 nozzle attachments, and 80 PSI adjustable pressure from the HD4000 carry over, making it a capable but lighter-duty version of the best overall pick.

Pros

  • Tank size: 3 gallons
  • Battery life: 2-2.5 hours, 50+ gallons per charge
  • Max pressure: 80 PSI
  • Nozzles: 6 included

Buying Guide

Choosing the right battery powered sprayer for your needs can be a daunting task. With so many products on the market, it can be hard to know which one will fit your requirements. It is important to consider some features when selecting a sprayer, such as capacity, battery life, sprayer wand, and nozzles. That’s why this guide is here to help you choose the perfect battery powered sprayer for your needs. The size and capacity is important if you are a frequent user or need to cover large areas. Capacity refers to the amount of fluid that the tank can store, usually ranging from 2-4 gallons. If you want to cover larger areas or need more fluid, then you’ll need to select a battery powered sprayer with a higher capacity. Battery life is also an important factor to consider because it will determine how long the sprayer can run without needing to be recharged. Before making a purchase, check the wand specs — it is an important piece of equipment that will determine the range of your spray pattern and the accuracy of your spraying. The sprayer should also have a good selection of nozzles, so you can customize your spray pattern depending on the job.
