LOOK FOR THE STAR – The 18v 5.0ah battery BL1850B will work with your 18v machine if it has a star on the connector plate, has a yellow connector plate with a star or has a yellow connector plate only.

The Makita 18v 5.0Ah Li-ion batteries charge with existing DC18RA and DC18RC chargers with an unbeatable 45 minute charge time.

Through this two way communication between charger and battery, the charger can recognise the battery and recall its charging history analyse the batteries condition and usage and charge the battery accordingly.

The weight saving means that Makita can have 5.0Ah from a battery weighing the same as the existing BL1830B 3.0Ah lithium ion battery.

Not only is it the same weight but also you will have much more power and a longer lasting battery life.
