Your DeWalt charger is an essential component of keeping your power tools topped up and running smoothly, but is it safe to leave the charger itself plugged in?
Whether you’re a DIYer or a professional on the job, knowing how to properly handle your DeWalt power tools and batteries is important. But the same is true for battery chargers, including DeWalt’s new charging station that can charge four batteries. When it comes to leaving your charger powered in, DeWalt states that when there’s no battery attached, the device should be disconnected. So the next time you remove a battery for use, go ahead and unplug the charger from the power supply.
The reason for this is that when a charger is left plugged in, the contacts are live. So if there’s no battery in the charger and metal somehow touches those contacts, the device can actually short out. Even tiny metal shavings can cause this to happen. Cleaning the charger while it’s plugged in can also be dangerous, as you can get shocked.
