Frequently Asked Questions

Makita batteries are compatible within each respective battery platform. 40V max XGT® batteries are fully compatible with XGT® products (including 80V (40V max X2) XGT® products powered by two 40V max XGT® batteries). The XGT® System includes 40V max 2.5Ah, 4.0Ah, 5.0Ah, and 8.0Ah batteries.
Every Makita® Lithium-Ion Tool, Battery, and Charger is warranted to be free of defects from workmanship and materials for the period of THREE YEARS from the date of original purchase.
No, Makita chargers are designed so that they will not overcharge a Lithium-Ion battery. For example, the Makita Rapid Optimum Charger (DC18RC) communicates with Makita 18V Lithium-Ion batteries to detect its charge level. Upon reaching a full charge, the charger goes into a maintenance mode and actively monitors the battery's charge level to keep it fully charged.
No. Makita recommends simply charging a brand new battery to a full charge before using it.
