Battery Powered Backpack Sprayer FAQs

How far will a backpack sprayer spray?

A battery powered backpack sprayer can spray upwards of 30 feet with the right nozzle using a stream.

Most spray applications don’t require that kind of distance, but if you are spraying ornamental trees with herbicides or spraying pesticide on hard to reach areas, the ability to spray at greater heights is accomplished with battery powered backpack sprayers.

This is one area when traditional pump sprayers fall short. If you have these types of projects around your house you will definitely want to invest in a powered sprayer.

How much does a backpack sprayer cost?

Battery powered backpack sprayers will range in price from around $100 to $300. 

The price range varies due to the different components used, the battery quality used and the overall technology that goes into the sprayer.

You can find a quality sprayer while keeping your budget in mind.  One of our favorite sprayers we reviewed  is priced around $150.00 and out performs many higher priced sprayers.

  • DO NOT incinerate the battery pack even if it is severely damaged or is completely worn out. The battery pack can explode in a fire. Toxic fumes and materials are created when battery packs are burned.
  • DO NOT charge or use battery in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Inserting or removing the battery from the charger may ignite the dust or fumes.
  • If battery contents come into contact with the skin, immediately wash area with mild soap and water. If battery liquid gets into the eye, rinse water over the open eye for 15 minutes or until irritation ceases. If medical attention is needed, the battery electrolyte for Lithium-Ion batteries is composed of a mixture of liquid organic carbonates and lithium salts.
  • Contents of opened battery cells may cause respiratory irritation. Provide fresh air. If symptoms persist, seek medical attention. WARNING: Burn hazard. Battery liquid may be flammable if exposed to spark or flame.
  • Charge the battery packs only in Chapin chargers.
  • DO NOT splash or immerse in water or other liquids. This may cause premature cell failure.
  • DO NOT store or use the tool and battery pack in locations where the temperature may reach or exceed 105 degrees Fahrenheit (40 degrees Celsius) (such as outside sheds or metal buildings in summer).

WARNING: Never attempt to open the battery pack for any reason. If battery pack case is cracked or damaged, do not insert into charger. Do not crush, drop or damage battery pack. Do not use a battery pack or charger that has received a sharp blow, been dropped, run over or damaged in any way (i.e., pierced with a nail, hit with a hammer, stepped on). Damaged battery packs should be returned to service center for recycling.

WARNING: Fire hazard. Do not store or carry battery so that metal objects can contact exposed battery terminals. For example, do not place battery in aprons, pockets, tool boxes, product kit boxes, drawers, etc., with loose nails, screws, keys, etc.

Transporting batteries can possibly cause fires if the battery terminals inadvertently come in contact with conductive materials such as keys, coins, hand tools and the like. The US Department of transportation Hazardous Material Regulations (HMR) actually prohibit transporting batteries in commerce or on airplanes (i.e., packed in suitcases and carry-on luggage) UNLESS they are properly protected from short circuits. So when transporting individual batteries, make sure that the battery terminals are protected and well insulated from materials that could contact them and cause a short circuit. NOTE: Lithium-Ion batteries should not be put in checked baggage.


Chapin chargers are designed to charge Chapin battery packs in 3.5-4 hours depending on the pack being charged.

  2. Insert the battery pack (C-12) into the charger as shown in figure A.
  3. The red light on the charger is continuously on when the battery is charging.
  4. The green light on the charger is continuously on when the battery is charged. The pack is fully charged and may be used at this time or left on the charger.
