Makita Y-00309 18V 5AH Battery & Rapid Charger Starter Kit

The Makita Y-00309 kit is a simple, cost-effective way to step into the 18V LXT platform—or add capacity to an existing fleet—without buying a full tool combo. It pairs the BL1850B 5.0Ah battery with the DC18RC Rapid Optimum Charger so crews can work longer and get back to 100% in as little as 45 minutes. The DC18RC actively manages current, voltage, and temperature and uses a built-in cooling fan to move air through the pack during charging for consistent cycle times. The BL1850B includes a four-LED fuel gauge to check remaining power at a glance and is compatible with Makita 18V LXT tools featuring Star Protection (Star Symbol™ / yellow battery receiver). This kit is a practical add-on for any “tool-only” purchase or to replace worn batteries with a high-capacity pack and a fast, reliable charger.
