  • Reaches full charge in 45 minutes or less
  • LED charge level indicator allows user to monitor battery charge
  • Compatible with 18-Volt LXT tools
The Makita 18-Volt LXT Lithium-Ion battery charges faster and works longer than standard Lithium-Ion batteries, giving you and your cordless tools unmatched performance and productivity to take on the most demanding applications. The Makita 5.0Ah battery, model BL1850B, combines more run time (65% more run time per charge than the Makita BL1830 battery) with a category-leading charge time of only 45 minutes so it spends more time working and less time sitting on the charger. For added convenience, it also features an on-board LED charge level indicator to monitor battery charge. The 18-Volt LXT 5.0Ah battery is compatible only with Star Protection tools, indicated by the Star Symbol and/or Yellow Battery Receiver under the tool. Makita 18-Volt Lithium-Ion batteries resist self-discharge so they're ready for use even after long periods of storage. The Makita Rapid Optimum Charger (sold separately) is a smart-charging system that communicates with the battery during the charging process to monitor current, voltage and temperature. This advanced charging technology helps optimize battery life and deliver a faster charge. In addition, the Charger has a built-in fan to cool the battery for faster and more efficient charging, even in hot weather conditions. For improved tool performance and extended battery life, Makita created STAR Protection Computer Controls.
  • Integrated LED battery charge level indicator allows user to monitor battery charge
  • Provides up to 65% more run time per charge compared to BL1830
  • Reaches full charge in 45 minutes or less
  • Compatible with 18-Volt LXT tools
  • Battery delivers consistent power and run time in extreme temperatures, even in winter (-4° F/-20° C)
  • Star protection allows the tool and battery to exchange data in real time to protect against overloading, over-discharging and overheating
  • Impact-resistant outer case and shock-absorbing inner-liner are engineered to protect the battery
  • Sixteen contact terminals maintain a constant connection with the tool to help prevent power loss or fluctuation, even during high-vibration applications
  • Battery resists self-discharge and remains ready for use even after long periods of storage

Is it normal for it to take one hour to charge one of these batteries?

Asked by: John
As the manufacturer said, it will take approximately 45 mins to fully charge the battery. Temperature is another factor that may make charging process longer

Hi, What 3.0Ah, 4.0Ah ... means ? Can I use any of them on my tool ? It it the capacity ? So higher is the number, longer I can use ?
Asked by: Bruno
I use the 3, 4 and 5 amp hour batteries on all my Makita tools. I haven't noticed a huge difference but I'm assuming it's the capacity. They all last a very long time and charge quickly.

Asked by: rj
Yes. All of the Makita 18-volt LXT Lithium-ion tools use the same style battery. The latest version battery with the fuel indicator is just an improvement to the earlier version.

Would it be easy to cut 2 feet long of 1 inch thick Oak with this?

Would it be easy to cut 2 feet long of 1 inch thick Oak with this?
Asked by: Howie
Thank you for your question. You could make this cut, but it would consume several blades and it would be extremely slow. I would recommend using a circular or reciprocating saw for this job.
