Our take on the Makita BL1840B-2 18-Volt 4.0Ah LXT L.E.D. Lithium-Ion Charging Battery, 2-Pk

This is a two-pack of Makita's 18V LXT 4.0Ah lithium-ion slide batteries, the mid-capacity pack in the LXT line. Each has a built-in LED charge gauge, reaches full charge in about 40 minutes on a compatible Makita charger, and carries Star Protection circuitry against overload, over-discharge and overheating. The 4.0Ah size sits between the compact 2.0Ah and the high-capacity 5.0Ah and 6.0Ah packs: more runtime than the small packs, lighter than the big ones. It suits LXT owners who want a spare pair for heavier tools like circular saws and grinders.
