The Makita LXT 18V 4.0Ah Lithium-Ion battery and charger are designed for professional tradespeople and serious DIYers who need reliable, long-lasting power for their Makita LXT tools. The key benefit is extended runtime and durability through advanced battery management, with a potential caveat being the proprietary charging system. This system offers 280% more lifetime work, 2x more cycles, and significantly reduced self-discharge compared to older battery technologies. Key features include STAR Protection Controls, a built-in memory chip, and sixteen firm holding contact terminals for stable power delivery.

STAR Protection is a communication technology that allows the tool and battery to monitor conditions in real-time. It protects against overloading, over-discharging, and overheating, thereby extending the battery's life and ensuring safe operation.
Runtime varies significantly based on the tool, application, and intensity of use. However, the 4.0Ah capacity generally provides substantially longer runtime compared to smaller capacity batteries (e.g., 1.5Ah or 2.0Ah) for most Makita LXT tools.
This 4.0Ah battery is compatible with Makita 18V LXT Lithium-Ion chargers. However, to benefit from the latest charging technologies and optimize battery life, using the charger recommended for the LXT system is advised.
Makita Lithium-Ion batteries have low self-discharge rates, meaning they hold their charge well during storage. It's generally recommended to charge the battery when its charge level is low or before starting a significant job. Avoid storing the battery in a completely depleted state for extended periods.
Makita typically offers a limited warranty on their Lithium-Ion batteries, often covering defects in workmanship and materials for a specific period, usually one year from the date of purchase. Please refer to the product manual or Makita's official website for precise warranty details.
While Makita chargers are designed with features to prevent overcharging, it's best practice not to leave batteries on the charger for excessively long periods after they are fully charged. Removing the fully charged battery and storing it separately can help maintain its optimal condition.
Ensure the battery is properly seated in the charger. Check that the charger is plugged into a working outlet. Clean the battery and charger terminals with a dry cloth. If the issue persists, contact Makita support.
Verify the battery is charged. Ensure the battery is correctly installed in the tool. Check the tool's power switch. If the battery is low or depleted, charge it. The STAR Protection system may have cut power due to overload, over-discharge, or overheating; allow the battery to cool down and reset.
The battery may be nearing the end of its service life after many charge cycles. Ensure the battery is fully charged. Check for any debris or obstructions in the tool that might be causing it to work harder. Clean battery terminals for optimal contact.
This can occur during heavy use or charging in hot environments. Allow the battery and charger to cool down completely before resuming use or charging. Ensure charging is done in a well-ventilated area. If overheating is persistent, contact Makita support.
Setup: To set up, simply slide the Makita LXT 18V 4.0Ah battery onto a compatible Makita LXT charger until it clicks into place. The charger will indicate when the battery is fully charged.
Compatibility: This battery is designed exclusively for use with all Makita 18V LXT Lithium-Ion cordless machines. It is also compatible with Makita 18V LXT Lithium-Ion chargers.
