Is this battery worth it over a cheaper third-party pack?

For heavy use, yes. Genuine Makita cells and Star Protection are the main reason to pay more. Light users may find a clone adequate, but clones often lack the same protection circuitry.

How long does the 3.0Ah pack run?

Expect roughly 1 to 2 hours of intermittent drilling and driving, less in high-draw tools like circular saws. Runtime depends on the tool and load.

Will it fit my Makita 18V LXT tools?

Yes. It works with all Makita 18V LXT tools and chargers, including the 30-minute rapid charger.

How does it compare with the 4.0Ah and 5.0Ah packs?

The 3.0Ah is lighter and cheaper but gives less runtime. The 4.0Ah and 5.0Ah packs add capacity at more weight and cost.

How long does it take to charge?

About 30 minutes on a compatible Makita LXT charger.
