Our take on the Makita ADBL1840B Outdoor Adventure 18V LXT 4Ah Battery

The Makita ADBL1840B is a 4.0Ah 18V LXT lithium-ion battery from Makita's Outdoor Adventure line, which pairs the battery with an included 18V LXT flashlight. It is a spare or replacement pack for the large LXT cordless ecosystem: drills, drivers, saws, trimmers, blowers and the Outdoor Adventure lights. Against higher-capacity LXT packs it trades runtime for lighter weight and a smaller footprint, and against cheaper third-party packs it offers Makita's own cells and built-in protection circuitry. Owners of LXT tools generally treat it as a dependable mid-capacity pack rather than a long-run workhorse.

Makita ADBL1840B Outdoor Adventure 18V LXT Lithium-Ion 4.0Ah Battery

Questions and answers

Is this battery compatible with all Makita 18V LXT tools?
Yes. It is a standard 18V LXT slide-on pack, so it fits LXT drills, drivers, saws, trimmers, blowers and lights. It does not fit Makita's 40V XGT or 12V CXT tools.
Does it come with a charger?
No. The pack is sold with an 18V LXT flashlight, not a charger. Any Makita LXT charger will charge it.
How does 4.0Ah compare with 5.0Ah or 6.0Ah LXT packs?
It gives roughly two-thirds the runtime of a 6.0Ah pack in the same tool, but it is lighter and smaller. Choose the larger packs for long cutting or blowing sessions and this one for lighter, shorter jobs.
Can I leave it on the charger or in a hot car?
Makita's protection circuitry guards against overload and over-discharge, but heat shortens lithium-ion life. Store it cool and dry and charge it before long storage.
Is the included flashlight useful?
It runs on the same LXT pack, so it is handy for camping, power outages and dark work areas. If you already own LXT lights, the battery alone is the main draw.
Where is the Makita ADBL1840B Outdoor Adventure 18V LXT 4Ah Battery cheapest?
At Amazon, for $85.71, 42% under what the other stores charge, as of our latest check.
Where can I buy the Makita ADBL1840B Outdoor Adventure 18V LXT 4Ah Battery?
8 stores we checked sell it, including Ace Tool Group, Tool Nut, Jobsite Power Tools, allseasonsestore, My Tool Store.
