Using the Makita BL1840BSC2 Starter Pack is easy. First, charge the 18V LXT Lithium - Ion 4.0Ah batteries using the included DC18SD charger. It takes about 90 minutes for a full charge, and you can check the charge level with the integrated L.E.D. indicator on the battery. Once the batteries are charged, insert them into your Makita 18V 'bare tools' or the included XAG25Z 18V LXT Angle Grinder. Remember, this battery pack is only compatible with Star Protection tools, so look for the Star Symbol™ or the Yellow Battery Receiver under the tool. When using the tools, the Star Protection Computer Controls™ will protect them from overloading, over - discharging, and overheating. As for maintenance, keep the batteries in a cool, dry place when not in use. The impact - resistant outer case and shock - absorbing inner - liner already protect the battery, but avoid dropping or hitting it hard. Also, make sure the sixteen 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, you can reach out for support. And if you're using 36V (18V X2) LXT Tools, you can use two of these 18V LXT batteries together.
