Makita BL4040F 40V Max XGT 4.0Ah Li-Ion Battery

The Makita BL4040F (part number 1910N6-8) is a state-of-the-art 40V Max XGT® Li-Ion battery pack engineered to deliver high-output power and extended runtime for the most demanding professional applications. Positioned as a superior alternative within the XGT® platform, the BL4040F utilizes advanced high-efficiency cells that provide increased power delivery compared to standard 4.0Ah models, without increasing the overall weight or footprint of the unit.

Advanced XGT® Technology and Construction

Designed to withstand the rigors of industrial jobsites, the Makita BL4040F features a robust outer casing and a shock-absorbing internal liner. This battery is purpose-built for high-drain tools such as circular saws, rotary hammers, and angle grinders. Key technical advantages include:

• Next-Generation Cell Chemistry: Optimized for high-load endurance, ensuring the battery maintains peak voltage even under heavy continuous stress.

• Smart Digital Communication: Integrated circuitry allows the battery and tool to exchange data in real-time, protecting against overload, over-discharge, and overheating.

• Rapid Charging Capabilities: When paired with the Makita DC40RA or DC40RB rapid chargers, a full charge is achieved in approximately 45 minutes, significantly reducing operational downtime.

• Integrated Fuel Gauge: A 4-LED charge indicator allows for immediate monitoring of remaining energy levels.

• Extreme Durability: Water and dust-resistant construction (IP-rated design) ensures reliable performance in harsh outdoor environments.

Operational Efficiency and Compatibility

The BL4040F is fully compatible with the extensive Makita 40V Max XGT® ecosystem. Its lightweight design (approx. 0.94 kg) provides an excellent power-to-weight ratio, maintaining tool balance and reducing operator fatigue during overhead or prolonged tasks. By utilizing the XGT® digital communication system, the battery optimizes power output based on the specific tool's requirements, effectively extending the overall life cycle of both the battery and the motor.
