It allows to continuously adjust the working pressure without producing any unnecessary sound, plus its battery operation time lasts longer.

The Birchmeier REA 15 AZ1 Backpack Sprayer has a change battery system which is proven to work without any interruption. It offers comfort even during a long period of use because it features a unique and ergonomic design. Everything is check and controlled by its electronics including the constant rotational speed, it detects the status of the electrical system if it is either on or off, and it monitors the charge level of the battery. Its hollow cone nozzle helps to equally distribute the product. There is no electrical connection required between the trigger assembly and the motor so it provides low interferences and all accessories can be easily and readily attached.

    Excellent sprayer

    By Angelo on 08/09/2019

    If it hadn't been for the oetiker clamps on the pump I would have given it 5 stars. The connecting hoses to pump blew off within a minute of turning and then spraying. I replaced them with worm hose clamps and that did the trick. This is the best sprayer I have ever had. I've worn out many through the years. If you have large jobs that require a lot of use, this is the one for you. it went for hours and I did not have to break my work cycle to recharge. Charges back up within 30 minutes if you are going to do all day jobs. A great buy for the price

Are there spare batteries for the Birchmeier REA 15 AZ1 Backpack sprayer?

Can you purchase a spare battery since I'd have no way to charge on my pest control truck? Does it pump all the way to empty? The Ryobi electric one I have won't pump anymore when it's down to the last gallon, which is not ideal for professionals.
