Our take on the Accessories- BL1850B

The Makita BL1850B is a 5.0Ah 18V LXT lithium-ion battery pack for Makita's 18V cordless tools. It charges in about 45 minutes on Makita's rapid chargers, which is faster than most rival 5.0Ah packs, and it carries a built-in fuel gauge and a four-terminal contact block. It suits owners already on the LXT platform who want longer runtime from their saws, drills and impact drivers. Against generic 5.0Ah packs it wins on charge speed and platform compatibility; against Makita's own 6.0Ah and 5.0Ah XGT packs it gives up some runtime and is not cross-compatible with XGT tools.

Questions and answers

Does the BL1850B work with all Makita 18V tools?
Yes. It fits Makita's 18V LXT tools and chargers. It does not fit XGT 40V tools or older NiCad platforms.
How long does it take to charge?
About 45 minutes on a Makita rapid charger such as the DC18RC. Slower chargers take longer.
Is 5.0Ah enough for a circular saw?
It handles moderate cutting well. For all-day saw work, many owners carry two packs and rotate them through the charger.
Does it have a charge indicator?
Yes. A built-in fuel gauge on the pack shows the remaining charge at the press of a button.
Is it worth it over a cheaper third-party battery?
Makita's pack has the fuel gauge, the four-terminal contact block and consistent cell quality. Third-party packs cost less but vary in cell quality and warranty support.
What is in the box?
The battery pack alone. Chargers and tools are sold separately.
