Troubleshooting Guide for Battery Backpack Sprayers Not Turning On or Charging

Check the Power Switches

- Ensure both the red toggle switch and the silver knob are in the off position.

- Verify the silver knob clicks when turned left to the off position.

- Confirm the red toggle switch shows an “O” symbol when off.

Check the Fuse

- Locate the fuse behind the cover marked ‘Fuse’ at the base of the unit.

- Inspect the fuse for a broken metal strip or blackened areas inside the glass tube.

- Replace a damaged fuse with one of the same ratings (10A 250V).

- Try turning on the sprayer after replacing the fuse.

Check the Lights in Front of the Unit

- Turn the unit on and observe the status lights.

- Red light only: unit needs charging.

- Red and green lights: unit is fully charged.

- No lights: charge the unit for 6-8 hours and retry.

Check the Charger Functionality


- Ensure you are using the original charger.

- Visually inspect the charger for frayed cables, cracks, or loose connections.

- Plug the charger into a working outlet and watch for indicator lights (red for charging, green for fully charged).

- Try a different outlet if no lights appear.

- Use a multimeter to check the output voltage (13.8-14.4V for sealed lead-acid batteries; specified voltage for lithium-ion batteries).

- Replace the charger if the voltage is out of range.

Check the Connection Points

- Inspect the charger and sprayer’s charging port for dirt, debris, or corrosion.

- Clean the connectors with a soft cloth and contact cleaner if necessary.

- Ensure the charger is securely connected to the sprayer.

- Check for loose or damaged components around the charging port.

Check the Battery Connections

- Inspect battery connections for cleanliness and lack of corrosion.

- Verify wire connections are tight and secure.

- Look for any loose wires or disconnections.

Assess Battery Health

- Visually inspect the battery for swelling, leaks, or corrosion.

- Use a multimeter to measure the battery voltage (12-13V for a fully charged 12V battery).

- Charge the sprayer for 6-8 hours if you don’t have a multimeter and see if it powers on.

- Replace the battery if it does not hold a charge or shows significantly lower voltage.

Seek Professional Help

- Contact customer support if the issue persists after these steps.

- Mention the troubleshooting steps taken and any observations.

Additional Tips

- Regularly check and clean battery and charger connectors.

- Store the sprayer in a cool, dry place with a full battery charge.
