Question 1

can i charge a different brand 20v battery with my dewalt charger? it looks like it fits.

Accepted Answer

No, you must not charge a different brand's 20v battery with your DeWalt charger, even if it looks like it fits. Doing this is dangerous and creates a serious risk of fire, electric shock, or electrocution. The charger is specifically designed only for DeWalt rechargeable battery packs. Using it with another brand can cause the other battery to overheat and burst, leading to injury or property damage. Even if the physical connection seems correct, the required electrical communication and charging profile are different. A charger designed for one type of battery pack can be dangerous for another. You must only use the charger specified by the manufacturer for any battery pack. Keep your DeWalt charger and batteries as a dedicated system.

Question 2

the worklight on my dewalt impact driver won't turn on, is there a setting for it?

Accepted Answer

The worklight is activated by the trigger switch. There is no independent on/off setting. If the tool runs but the light does not illuminate, the LED is likely faulty or there is an internal connection problem. First, ensure the battery pack is properly installed and has a charge. A fully depleted battery may not provide enough power for the light. Operate the tool in a dim area. The light should illuminate when the trigger is pulled and may remain on for a short delay after release. If that didn't work, the issue is internal. Do not attempt to disassemble the housing to access the worklight. Never modify the power tool. Damage or personal injury could result. Heads up: This requires professional repair. Take the tool to an authorized service center for diagnosis and service.

Question 3

dewalt impact wrench making a weird grinding noise when i pull the trigger, should i keep using it?

Accepted Answer

Stop using it immediately. A grinding noise indicates internal damage or binding of moving parts. Continuing use risks complete tool failure or personal injury. Disconnect the battery pack. Check for an obvious cause: ensure no accessory (bit, socket) is damaged and is properly installed. Remove the accessory and inspect the chuck and anvil for visible damage or debris. If that didn't work, the tool requires service. Do not disassemble it. Have your power tool serviced by a qualified repair person using only identical replacement parts. This maintains the tool's safety. Using a damaged tool is dangerous. Heads up: Regular maintenance prevents this. Check for misalignment, binding of parts, or breakage before use. Many accidents are caused by poorly maintained tools.

Question 4

is it safe to store my dewalt batteries in a toolbox with my drill bits and screws?

Accepted Answer

No, it is not safe. Storing loose batteries with metal objects like drill bits and screws is a major short-circuit risk. The battery terminals can connect with these metal items. If they bridge the positive and negative terminals, it can generate enough heat to cause burns or start a fire. You should store the battery pack by itself, or in its original compartment in the kit box where it is isolated. When transporting individual packs, ensure the terminals are protected. You can use the plastic terminal cover that sometimes comes with new packs, or place a bit of electrical tape over the contacts. There is no safe alternative to keeping batteries and metal objects separate. Also, do not throw spent batteries in the trash. Recycle them at an authorized DeWalt center or retailer.

Question 5

my dewalt impact driver bit keeps falling out of the chuck, how do i lock it in?

Accepted Answer

The bit isn't fully seated in the quick-release chuck. The chuck only accepts 1/4" hex accessories or 1" bit tips. First, place the forward/reverse button in the lock-off (center) position or remove the battery pack. Firmly push the bit into the chuck until you feel and hear it click into place. It should be fully seated. To remove, grasp the bit and pull it straight out. If that didn't work, inspect the chuck and the bit. The bit's hex shank might be worn or dirty, preventing a good grip. Try a different, clean bit. If the new bit also falls out, the internal hog ring in the chuck may be worn or damaged. Heads up: Always ensure the tool is locked off or disconnected before changing accessories. A wrench or key left attached to a rotating part can cause injury.

Question 6

can i use my dewalt 20v charger outdoors? it's drizzling a bit.

Accepted Answer

You should not use the charger in the rain or snow. Doing so creates a risk of electric shock. Water getting inside the charger is a serious hazard. Here's what you need to do for safe outdoor charging: Always provide a dry location for the charger. This could be inside a garage, shed, or under a substantial canopy that protects from all moisture. If you must use an extension cord to reach that dry location, it must be a cord suitable for outdoor use. The label on the cord will state if it's for outdoor use. That outdoor extension cord also needs the correct wire gauge (AWG) for its length to prevent overheating. Refer to the gauge chart: for a 100-foot cord at 120V, you need 14 AWG wire. If that's not possible, wait until you can move the charger and battery to a dry, indoor location. Never operate the charger with a damaged cord or plug, and don't place it on a soft surface that can block its ventilation slots. Heads up: Pull by the plug, not the cord, when disconnecting. This prevents damage to the electrical connections.

Question 7

dewalt impact wrench feels weak, barely spins, is the battery dead?

Accepted Answer

Likely cause is voltage drop from an undersized extension cord. Using a cord with too small a wire gauge (too high a number) causes power loss and overheating. Fix: Check your extension cord's length and amperage rating. Match it to the gauge table. For a standard 120V tool, if your cord is 50 feet long, you need at least 16 AWG wire. If it's 100 feet, you need 14 AWG. Use the next heavier gauge if in doubt. Plug the tool directly into a wall outlet to test. If power returns, your extension cord was the problem. If that didn't work, the battery pack may be depleted or faulty. Try a second, known-good battery pack from your kit. If the tool works with the second pack, charge the first one. If the charger indicates a problem with that pack, it may need service. Heads up: Do not force the tool. Using the wrong power source damages performance and can overheat the charger cord.

Question 8

my dewalt impact driver charger light is blinking red, what does that mean?

Accepted Answer

The blinking red light indicates a problem with the battery pack or the charger itself. The specific fault is either a 'PROBLEM PACK OR CHARGER' or a 'HOT/COLD DELAY' condition. First, disconnect the battery pack from the charger and unplug the charger from the outlet. Check the battery terminals and the charger cavities for any conductive foreign material like metal dust, chips, or grinding debris. Clean them out if present. Let the battery pack and charger cool down or warm up to room temperature if they were in an extreme environment. Reconnect everything. If the light is solid red, it's charging. If it's solid green, the pack is charged. If that didn't work, the issue is likely a faulty battery pack or a damaged charger. Do not attempt to disassemble the charger. If the charger has received a sharp blow, been dropped, or has a damaged cord or plug, take it to an authorized service center. Never try to charge the battery pack with any charger other than the specified DeWalt one. Heads up: Always unplug the charger from the power supply when there is no battery pack in the cavity to prevent a potential short.
