This Makita 18V 4.0Ah LXT Lithium Battery & Charger set (BL1840) is designed for professionals and serious DIYers who need reliable, extended power for their Makita LXT tools. The key benefit is increased runtime and faster charging, allowing for less downtime on job sites. A potential caveat is that while it charges Ni-MH and Ni-Cd batteries with adapters, its primary focus is LXT Lithium-Ion. This package includes two 4.0Ah batteries offering 33% more runtime than previous models and a DC18RC fast charger with advanced cooling and control for optimal battery longevity and quick charging.

Yes, the BL1840 batteries are compatible with all Makita 18V LXT Lithium-Ion tools. They will not work with older Makita 18V Ni-Cd or Ni-MH tools unless specific adapters are used (which are not included in this set).
Store batteries in a clean, dry, and cool environment (ideally between 50°F and 80°F or 10°C and 27°C), away from direct sunlight and heat sources. Avoid storing them fully discharged.
The protection circuit prevents over-discharge, over-current, and overheating, which helps to significantly extend the battery's lifespan and ensures safer operation.
The DC18RC charger is designed for Makita 18V LXT Lithium-Ion batteries. However, with optional adapters, it can also charge older Makita Ni-MH and Ni-Cd batteries.
Yes, the Makita 18V 4.0Ah LXT Lithium batteries (BL1840) are designed to be the same size and weight as the 3.0Ah BL1830 batteries, ensuring compatibility with tools designed for them.
The charging indicator lights on the DC18RC charger will indicate the charging status. When charging is complete, the lights will show a solid green or a steady series of lights, depending on the specific charger model's display.
Ensure the battery is correctly seated in the charger. Check if the charger's power cord is securely plugged into a working outlet. Clean the battery and charger contacts. If the battery is excessively hot or cold, allow it to reach room temperature before attempting to charge.
Verify the battery is fully seated in the tool. Ensure the tool is compatible with the 18V LXT system. Check the tool's power switch and safety lock. If the battery indicator lights on the battery show an error, refer to the tool's manual or contact support.
Batteries degrade over time with use. Ensure the battery is not exposed to extreme temperatures during storage or use. Clean the battery contacts. If runtime is significantly less than expected, the battery may be nearing the end of its lifespan.
Refer to the DC18RC charger's manual for specific error code interpretations. Common issues include faulty battery, charger malfunction, or high/low temperature charging environments.
Setup: To begin using the batteries, simply slide a fully charged battery firmly into the tool or charger until it clicks into place. Ensure the battery contacts and the tool's power connector are clean before insertion.
Compatibility: The BL1840 batteries are fully compatible with all Makita 18V LXT Lithium-Ion cordless tools. Look for the star symbol or a yellow connector on your tool for guaranteed compatibility.
