Charge the Pesti rechargeable electronic sprayer after each use to keep it ready for the next application.

Begin by removing any residual chemical from the tank and rinsing thoroughly with clean water using the sprayer’s rinse function or by filling the tank halfway, running the pump for a few seconds, and emptying it. Dry the exterior and allow the interior to air for a short time with the cap loosened to reduce corrosion and odor. Connect a USB C charging cable to the sprayer and to a reliable power source that supplies standard five volts and up to two amps for faster charging when supported. Watch the sprayer’s charging lights closely; a solid light typically means fully charged while a blinking light means charging is still in progress, and refer to the manual if the pattern differs. Avoid overcharging by unplugging within a few hours once the indicator shows full, and do not leave the device connected for days as prolonged trickle can shorten battery lifespan. Store the sprayer in its pouch or a dry, cool location with the battery charged to about fifty to seventy percent if you plan longer storage to preserve battery health.

Common mistakes include assuming the lights always mean full so people unplug too soon, which can leave the battery undercharged and reduce run time; always confirm the indicator pattern against the manual and allow a complete charge cycle. Another issue is charging with residual chemicals still in the tank which risks corrosion or electrical faults, so always rinse and dry the tank before connecting the cable. A third frequent problem is improper storage, like leaving the device in extreme temperatures or exposed to moisture; keep the sprayer in its pouch in a temperate, dry place and maintain a partial charge for long term storage.
