Expert Note

For professional users running multiple Makita 18V LXT tools, this 10-pack can significantly reduce downtime caused by battery changes and charging. Rotate the batteries between tools and chargers throughout the day to maintain a consistent power supply.

For the fastest turnaround, use a compatible Makita rapid charger such as the DC18RC or a multi-port charger for charging several batteries at once. Allow batteries to cool after intensive use before recharging, as charging a hot battery may increase the charging time.
