Model Number: BL1840B
The Makita BL1840B 4.0 Ah 18V LXT Li-Ion Battery from the ITS uses Makita’s optimum charging system, which produces 430% more runtime, and 2x more cycles over the lifetime of the batteries.
A 5x lower self-discharge keeps the 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 battery’s built-in memory chip communicates with the charger to maximize battery life using three active controls (current, voltage, and thermal).
With no memory effect, lithium-ion batteries can be “topped up” at any time with no effect on battery life.
