Important Safety Instructions for All Battery Chargers

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 attempt to charge the battery pack with any chargers other than a DEWALT charger. DEWALT chargers and battery packs are specifically designed to work together.
  • These chargers are not intended for any uses other than charging DEWALT rechargeable battery packs. Charging other types of battery packs may cause them to overheat and burst, resulting in personal injury, property damage, fire, electric shock or electrocution.
  • Do not expose the charger to rain or snow.
  • Do not allow water or any liquid to enter charger.
  • Pull by the plug rather than the cord when disconnecting the charger. This will reduce the risk of damage to the electric plug and cord.
  • Make sure that the cord is located so that it will not be stepped on, tripped over or otherwise subjected to damage or stress.
  • Do not use an extension cord unless it is absolutely necessary. Use of improper extension cord could result in risk of fire, electric shock or electrocution.
  • When operating a charger outdoors, always provide a dry location and use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
  • An extension cord must have adequate wire size (AWG or American Wire Gauge) for safety. The smaller the gauge number of the wire, the heavier the cord and thus the greater its capacity. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. The following table shows the correct size to use depending on total length of all extension cords plugged together, and nameplate ampere rating. If in doubt, use the next heavier gauge.

Minimum Gauge for Cord Sets

  • Do not place any object on top of the charger or place the charger on a soft surface that might block the ventilation slots and result in excessive internal heat. Place the charger in a position away from any heat source. The charger is ventilated through slots in the top and the bottom of the housing.
  • Do not operate the charger with a damaged cord or plug. Have them replaced immediately.
  • Do not operate the charger if it has received a sharp blow, been dropped or otherwise damaged in any way. Take it to an authorized service centre.
  • Do not disassemble the charger; take it to an authorized service centre when service or repair is required. Incorrect reassembly may result in a risk of electric shock, electrocution or fire.
  • The charger is designed to operate on standard 120V household electrical power. Do not attempt to use it on any other voltage. This does not apply to the vehicular charger.
  • Foreign materials of a conductive nature, such as, but not limited to, grinding dust, metal chips, steel wool, aluminium foil or any buildup of metallic particles should be kept away from the charger cavities and ventilation slots.
  • Always unplug the charger from the power supply when there is no battery pack in the cavity.

Charging a Battery (Fig. C, D)

  1. Plug the charger into an appropriate outlet.

  2. Insert and fully seat the battery pack until you hear an audible click.

  3. The red charging light(s) will continuously blink while charging.

  4. Charging is complete when the red charging light(s) remain(s) continuously ON.

  5. The battery pack can be left in the charger or removed. Some chargers require the battery pack release button to be pressed for removal.
    WARNING: Only charge batteries in air temperatures over 40 ° F (4.5 ° C) and below 104 ° F (+40 ° C).

  6. Charger will not charge a faulty battery pack, which may be indicated by the charging light(s) staying OFF. Take the charger and battery pack to an authorized service center if light(s) stay(s) OFF.

    NOTE: To remove the battery pack, some chargers require the battery pack release button to be pressed.

Hot/Cold Pack Delay
When the charger detects a battery pack that is too hot or too cold, it automatically starts a Hot/Cold Pack Delay, suspending charging until the battery pack has reached an appropriate temperature. The charger then automatically switches to the pack charging mode. This feature ensures maximum battery pack life. A cold battery pack may charge at a slower rate than a warm battery pack. The hot/cold pack delay will be indicated by the red light(s) continuing to blink but with the yellow light continuously ON. Once the battery pack has reached an appropriate temperature, the yellow light will turn OFF and the charger will resume the charging procedure.

DCB118 and DCB1112 Chargers
The DCB118 and DCB1112 chargers are equipped with an internal fan designed to cool the battery pack. The fan will turn on automatically when the battery pack needs to be cooled. Never operate the charger if the fan does not operate properly or if ventilation slots are blocked. Do not permit foreign objects to enter the interior of the charger.

Electronic Protection System
Li‑Ion tools are designed with an Electronic Protection System that will protect the battery pack against overloading, overheating or deep discharge. The tool will automatically turn off and the battery pack will need to be recharged.

Important Charging Notes

  1. The longest life and best performance can be obtained if the battery pack is charged when the air temperature is between 65 °F – 75 °F (18 ° C– 24 °C). DO NOT charge when the battery pack is below +40 °F (+4.5 °C), or above +104 °F (+40 °C). This is important and will prevent serious damage to the battery pack.
  2. The charger and battery pack may become warm to the touch while charging. This is a normal condition, and does not indicate a problem. To facilitate the cooling of the battery pack after use, avoid placing the charger or battery pack in a warm environment such as in a metal shed or an uninsulated trailer.
  3. If the battery pack does not charge properly:
    • Check the operation of the receptacle by plugging in a lamp or other appliance;
    • Check to see if the receptacle is connected to a light switch which turns the power off when you turn out the lights;
    • If charging problems persist, take the tool, battery pack and charger to your local service centre.
  4. You may charge a partially used pack whenever you desire with no adverse effect on the battery pack. Charger Cleaning Instructions WARNING: Shock hazard. Disconnect the charger from the AC outlet before cleaning. Dirt and grease may be removed from the exterior of the charger using a cloth or soft non‑metallic brush. Do not use water or any cleaning solutions.

Wall Mounting
Some DeWALT chargers are designed to be wall mountable or to sit upright on a table or work surface. If wall mounting, locate the charger within reach of an electrical outlet, and away from a corner or other obstructions which may impede air flow. Use the back of the charger as a template for the location of the mounting screws on the wall. Mount the charger securely using drywall screws (purchased separately) at least 1” (25.4 mm) long, with a screw head diameter of 0.28–0.35” (7–9 mm), screwed into wood to an optimal depth leaving approximately 7/32” (5.5 mm) of the screw exposed. Align the slots on the back of the charger with the exposed screws and fully engage them in the slots.
