Product Description

Model Number: BL1840

Barcode: 088381426749

The Makita LXT BL1840 18 Volt 4.0Ah Lithium-Ion (Li-ion) batteries use Makita's optimum charging system which produces 30% more runtime, and 2x more cycles over the lifetime of the BL1840 batteries.

A 5x lower self-discharge keeps the Makita BL1840 battery cells active and ready for use even after long periods of storage, charging at any time will have no effect on the battery.

Built-in shock absorbing features protect the battery and sixteen firm holding contact terminals reduce the risk of power loss/fluctuation in high vibration work environments.

The Makita BL1840 battery's built-in memory chip communicates with the charger to maximize battery life using 3 Active Controls (Current, Voltage & Thermal)

The Makita LXT BL1840 18 Volt 3.0Ah Lithium-ion (Li-ion) battery uses the latest Lithium-ion battery technology. With no memory affect Lithium-ion (Li-ion) batteries can be "topped up" at any time with no affect to battery life. The main benefit to this battery type is the weight - up to 40% lighter than Ni-CD makes these the favourites for power tools.
