Battery Sprayer Charging Steps
Power Off and Prepare
Before you start charging, always turn off your battery sprayer. This step keeps you safe and protects the equipment. If you skip this, the sprayer might turn on by accident. That could cause injuries or damage the battery. You also risk overheating or even fire.
Tip: Always check that the lid is closed and the battery compartment is dry before charging.
If your battery sprayer uses a removable battery, take the battery out before charging. This makes the process safer and easier.
Here are the steps you should follow:
Turn off the battery sprayer.
Make sure the lid is closed tightly.
Remove the battery if your model allows it.
Inspect the battery and compartment for any signs of damage or leaks.
Connect Charger
Use only the charger that matches your battery sprayer model. Using the wrong charger can damage the battery or even void your warranty. For example, the Battery Charger for Chapin Backpack Sprayer 4 Gal. 20V Lithium Black & Decker works only with that specific model. Other sprayers, like the Master Manufacturing Spot Sprayer, need different chargers.
Charger Model | Compatible Sprayer Models |
US Charger 183563 | Scotts 3 Gallon Lithium-ion Powered Pump Zero Wheeled Cart Sprayer, Smith 2 Gallon Lithium-Ion Powered Sprayer, LESCO Zero Pump 1 Gal Elite Premium Series, and more |
Plug the charger firmly into the sprayer’s charging port. Then, connect the charger to a proper wall outlet. Avoid using extension cords or power strips. This helps prevent interruptions and keeps the charging process safe.
Note: Never charge your battery sprayer in wet or damp areas. Water and electricity do not mix and can cause serious accidents.
Monitor Charging
Watch the indicator lights on your battery sprayer or charger. Most models have a light that shows when charging starts and when it finishes. For example, a red light may mean charging, while a green light means fully charged.
Charging times can vary by model. Here is a table with some common charging times:
Sprayer Model | Charging Time |
Graco Ultra Cordless Handheld Airless Sprayer | 35 minutes |
Field King Lithium-ion Battery Backpack Sprayer | 3.5 hours |
Graco 390 PC Cordless Airless Sprayer | Under 60 minutes |
Do not leave the battery sprayer charging for longer than needed. Overcharging can shorten battery life and may cause overheating.
Tip: Stay nearby while charging so you can unplug the charger as soon as the battery is full.
Disconnect Safely
Once the indicator light shows a full charge, unplug the charger from the wall outlet first. Then, disconnect it from the battery sprayer. This order helps protect both you and the equipment.
If you removed the battery earlier, place it back into the sprayer after charging. Make sure it fits snugly and the compartment is clean.
Some common mistakes to avoid:
Not fully charging the battery before use.
Using a charger that does not match your battery sprayer.
Charging in wet or unsafe areas.
Forgetting to clean and maintain your sprayer after each use.
Reminder: Always follow the manufacturer’s instructions for your specific battery sprayer. This keeps your equipment working well and helps you avoid problems.
