Will these batteries fit my Makita 18V tool?

They fit 18V LXT tools that carry the Star Symbol or have a yellow battery receiver. Older LXT tools without those markings are not listed as compatible.

How long does the charger take?

The DC18RC charges a 4.0Ah battery in about 40 minutes. It has one bay, so two packs charge one after the other.

Two BL1840B 18V LXT 4.0Ah batteries and one DC18RC Rapid Optimum Charger. No tools or case are included.

Is 4.0Ah enough for saws and grinders?

It runs them, but high-draw tools drain a 4.0Ah pack faster than a 5.0Ah or 6.0Ah pack. Two packs let you swap and keep working.

Can I leave the batteries in storage?

Yes. The cells resist self-discharge, so a charged pack stays ready after storage. The LED gauge shows the level when you pick it up.

What does Star Protection do?

It cuts the battery off on overload, over-discharge and over-heat, which protects both the pack and the tool.

What reviewers say

Owners of LXT tools generally rate the 4.0Ah packs as reliable workhorses with steady power and a charge gauge that saves guesswork. The rapid charger is the part most often singled out for how quickly it turns a pack around.

What people mention

RuntimeMixedOwners find the 4.0Ah packs fine for drills and drivers but short in saws and other high-draw tools.
Charge timePraisedThe rapid charger is repeatedly noted for refilling a 4.0Ah pack in well under an hour.
BuildPraisedThe impact-resistant case and shock-absorbing liner are seen as holding up to job-site drops.
Charge gaugePraisedThe LED indicator on each battery is called out as a simple way to check charge before a job.
CompatibilityMixedThe packs only work in LXT tools with the Star Symbol or yellow receiver, which catches some older-tool owners out.
