Using the DeWalt DCB2460C Starter Kit is a breeze. First, make sure you have the right tool that's compatible with 20V MAX* batteries. Then, simply slide the battery onto the tool until it clicks into place. You're ready to start working! When it comes to charging, use the included DCB1104 charger. Just insert the battery into the charger and plug it into a power outlet. The LED indicator on the battery will show you the charging status. As for maintenance, keep the batteries in a cool and dry place. Avoid exposing them to extreme temperatures. If the battery isn't going to be used for a long time, it's a good idea to charge it to about 50% and store it. And always handle the batteries with care to prevent any damage.
