When using the battery, make sure the tool is turned off before inserting or removing the battery. Avoid exposing the battery to extreme temperatures, as this can reduce its performance and lifespan. To charge the battery, connect it to a DeWalt 20V MAX* charger. You can check the charge status using the 3-LED fuel gauge. For maintenance, keep the battery clean and dry. Wipe it with a dry cloth if it gets dirty. If you're not going to use the battery for a long time, store it in a cool, dry place. Also, it's a good idea to charge the battery every few months to keep it in good condition.
