Built with Makita’s Star Protection Computer Controls™, it safeguards against overloading, overheating, and over-discharging. Delivering up to 65% more runtime compared to 3.0Ah packs, this battery charges in under 45 minutes with Makita’s Rapid Optimum Charger. Ideal for high-drain tools like saws, grinders, and blowers, it ensures your equipment runs longer and stronger on the job site or at home.
About Makita BL1850B 18V LXT Lithium-Ion 5.0Ah
Makita BL1850B 18V LXT Lithium-Ion 5.0Ah: The Perfect Balance of Power and Runtime
The Makita BL1850B 18V LXT Lithium-Ion 5.0Ah battery is one of Makita’s most popular power solutions, striking an ideal balance between extended runtime, manageable weight, and fast charging. Whether you’re running a heavy-duty circular saw, a hammer drill, or a high-powered blower, this battery delivers consistent performance to keep your work moving without interruption.
Key Features of the BL1850B
- Capacity: 5.0Ah for extended tool runtime.
- Technology: Star Protection Computer Controls™ for safety and battery life.
- Charge Time: Approx. 45 minutes with Rapid Optimum Charger.
- Compatibility: Powers over 275 Makita LXT tools.
Performance on the Job
With 5.0Ah of capacity, the BL1850B offers significantly longer runtime than lower-capacity packs without becoming too heavy. Professionals appreciate its ability to handle a full morning of work on a single charge, especially when paired with efficient brushless tools.
Charging Best Practices
- Use Makita’s Rapid Optimum Charger for the fastest, safest results.
- Allow the battery to cool for 15 minutes after heavy use before charging.
- Charge at moderate room temperatures for optimal cell health.
Storage and Maintenance
Store your BL1850B in a cool, dry place, ideally at a 40–60% charge if unused for extended periods. Avoid direct sunlight, extreme cold, or leaving the battery in tools for long storage periods.
Pro Tips
- Label batteries with purchase dates for easy rotation.
- Use high-capacity packs like the BL1850B for saws and grinders, saving smaller packs for drills and drivers.
- Clean the terminals regularly with a dry cloth to ensure a solid connection.
Mistakes to Avoid
- Running the battery until completely dead—recharge before it reaches zero.
- Leaving it on the charger overnight unnecessarily.
- Using non-Makita chargers that can damage cells.
Conclusion
The Makita BL1850B is a dependable powerhouse for anyone invested in the LXT platform. Offering excellent runtime, safety features, and compatibility with hundreds of tools, it’s the battery you’ll reach for when the job demands both endurance and reliability.
