Before using the battery pack and charger, read the safety instructions below and then follow charging procedures outlined. When ordering replacement battery packs, be sure to include the catalog number and voltage. READ ALL INSTRUCTIONS Important Safety Instructions for All Battery Packs  WARNING: Read all safety warnings, instructions, and cautionary markings for the battery pack, charger and product. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury. • Do not charge or use the battery pack in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Inserting or removing the battery pack from the charger may ignite the dust or fumes. • NEVER force the battery pack into the charger. DO NOT modify the battery pack in any way to fit into a non‑compatible charger as battery pack may rupture causing serious personal injury. Consult the chart at the end of this manual for compatibility of batteries and chargers. • Charge the battery packs only in DeWALT chargers. • DO NOT splash or immerse in water or other liquids. • DO NOT allow water or any liquid to enter battery pack. • Do not store or use the tool and battery pack in locations where the temperature may reach or exceed 104 °F (40 °C) (such as outside sheds or metal buildings in summer). For best life store battery packs in a cool, dry location. NOTE: Do not store the battery packs in a tool with the trigger switch locked on. Never tape the trigger switch in the ON position. • 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 lithium‑ion battery packs are burned. • Do not expose a battery pack or appliance to fire or excessive temperature. Exposure to fire or temperature above 265 °F (130 °C) may cause explosion. • Follow all charging instructions and do not charge the battery pack or appliance outside of the temperature range specified in the instructions. Charging improperly or at temperatures outside of the specified range may damage the battery and increase the risk of fire. • 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 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. • Battery liquid may be flammable if exposed to spark or flame. • Never attempt to open the battery pack for any reason. If the battery pack case is cracked or damaged, do not insert into the charger. Do not crush, drop or damage the 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 (e.g., pierced with a nail, hit with a hammer, stepped on). Damaged battery packs should be returned to the service center for recycling. Storage Recommendations The best storage place is one that is cool and dry, away from direct sunlight and excess heat or cold. Store the fully charged battery pack out of the charger. Battery Pack Cleaning Instructions Dirt and grease may be removed from the exterior of the battery pack using a cloth or soft non‑metallic brush. Do not use water or any cleaning solutions. Fuel Gauge Battery Packs (Fig. B) Some battery packs include a fuel gauge. When the fuel gauge button is pressed and held, the LED lights will indicate the approximate level of charge remaining. This does not indicate tool functionality and is subject to variation based on product components, temperature, and end‑user application. Transportation  WARNING: Fire hazard. Do not store, carry, or transport the battery pack so that metal objects can contact exposed battery terminals. For example, do not place the battery pack in aprons, pockets, tool boxes, product kit boxes, drawers, etc., with loose nails, screws, keys, coins, hand tools, etc. When transporting individual battery packs, make sure that the battery terminals are protected and well insulated from materials that could contact them and cause a short circuit. NOTE: Li‑ion battery packs should not be put in checked baggage on airplanes and must be properly protected from short circuits if they are in carry‑on baggage. 10
