  • 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.

  1. Plug the charger (C-13) into an appropriate outlet before inserting the battery pack.
  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.
  5. Blinking red and green lights on the charger indicates a defective battery and should properly be disposed of.

    Great sprayer

    By Paul on 09/16/2019

    It took several weeks for the unit to arrive, due to it not being a stocked item. I love the sprayer but had some issues with the pump leaking. Here are my issues and whether or not they were resolved. 1. Arrival time - Understandable due to item not being a warehoused item. 2. The boom/wand selector switch spewed tank contents when the pump was turned on. A good tightening of the screw that hold the switch fixed that leak. 3. The pump still spews tank contents (from the pump area) when the switch is in the wand position. I have not been able to fix this but all hoses are tight. I figured I'd have to jump through hoops to get this resolved ... so I just don't use the wand. 4. The pump sometimes runs normal, sometimes it sounds like it is over running...sometimes pulsates. Either way, I seem to get the correct pressure out of the nozzle so I'm assuming it is running at whatever speed necessary to keep the same pressure coming out. 5. This one is for the consumer to keep an eye on. Wash the tank after each use and make sure that the inline filter on the wand and the screen in the bottom of the tank are free of debris/sediment or whatever. This will cause the sprayer to lose pressure and you won't be efficient with your applications. Other than that, I'd like to see a way to remove the wand and its hose if you wish not to use it. When stowed away properly, it's not in the way of using the boom sprayer. I really like the product, but some fine tuning from the manufacturer is needed...specifically leaking at the pump when the pump is on.

    Only 2 real issues but they're big ones!

    By Gil on 05/08/2020

    1. The hand wands point of contact to the pump is a plastic nipple that the wands hose slips over and clamps to. The first time you create any kind of stress to this connection it snaps clean off. 2. The battery when fully charged will not last long enough to empty the 12 gallons. In fact I'n able to spray about 9 gallons before having to recharge. Correct these 2 items and you have 5 star review and not the 2 I gave it.

    A good investment

    By Richard on 05/27/2020

    I've had this sprayer for a year now and it is well made and very useful. My only negative comment is that I wish there was some kind of washout stopper at the bottom to make clean up easier. I have had to resort to tipping the thing over multiples after each use to fully rinse it out. However, I have ordered a battery powered siphon pump to help and otherwise just run both the boom and wand sprayers as the last stage of the rinse.
