Makita BL1850B 18 V LXT 5.0 Ah Lithium-ion Battery

The Makita BL1850B 18V LXT 5.0Ah Li-ion Battery is a slide-on power tool battery for the Makita 18V LXT cordless platform. Rated at 18 V with a 5.0 Ah capacity, it powers compatible cordless tools for sawing, drilling, and general construction tasks. Lithium-ion construction avoids the memory effect that affects older nickel-based batteries. The 5.0 Ah rating provides longer runtime between charges than standard-capacity packs on the same platform. This single battery works as a replacement or spare for users already equipped with 18V LXT tools. Compatibility covers the full Makita 18V LXT cordless power tool range.

Weighing approximately 630 g, the pack helps maintain tool balance during prolonged or overhead work. A full recharge takes about 45 minutes when paired with a compatible Makita rapid charger. An integrated LED fuel gauge shows remaining charge without removing the battery from the tool. The black housing uses a slide-on form factor standard across the Makita LXT system. No charger is included, so a separate compatible Makita charger is required for operation. The battery ships individually without a carrying case.
