Using this Makita 18V LXT Li - Ion Starter Pack is easy. First, take the 18V LXT Lithium - Ion 4.0Ah batteries (BL1840B) and insert them into the charger (DC18SD). The charger will start working right away, and you can use the L.E.D. indicator on the battery to check the charge level. Once the batteries are charged, you can use them with the included 18V LXT 3/8' / 1/4' Sq. Drive Ratchet (XRW01Z) or other compatible 18V bare tools. When using the tools, remember that the Star Protection Computer Controls™ are there to protect the battery and the tool from overloading, over - discharging, and overheating. Don't worry about the battery losing power quickly, as it resists self - discharge. As for maintenance, keep the battery and charger in a dry place. The impact - resistant outer case and shock - absorbing inner - liner of the battery already offer good protection, but try to avoid dropping or hitting it hard. Also, make sure the 16 contact terminals on the battery are clean for a good connection with the tool. This starter pack comes with a 3 - year limited warranty, so if you have any issues during this time, you can reach out to Makita. And remember, if you're using 36V (18V X2) LXT tools, you'll need to use two 18V LXT batteries together.
