Product Overview

  • Powers the expanding 18V LXT line of cordless tools
  • Extended Run Time; Powers 18V LXT and 18V Compact Tools
  • Battery has a 3-year limited warranty from date of purchase
The Makita 18-Volt Compact Lithium-Ion battery charges faster and works longer than standard compact lithium-ion batteries, giving you and your cordless tools unmatched performance and productivity to take on the most demanding applications. The Makita 2.0Ah battery combines more run time (50% more run time per charge than the Makita BL1815 battery) with a category-leading charge time of only 25-minutes, so it spends more time working and less time sitting on the charger. 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. Star Protection is communication technology that allows the tool and battery to exchange data in real time and monitor conditions during use to protect against overloading, over-discharging and overheating. Makita, the innovation leader in cordless tool technology, has the world’s largest cordless tool line-up powered by an 18-Volt lithium-ion slide-style battery.
  • Integrated LED battery charge level indicator allows user to monitor battery charge
  • Provides up to 50% more run time per charge compared to BL1815
  • Reaches full charge in 25-minutes or less
  • Compatible only with star protection tools, indicated by the star symbol and/or yellow battery receiver under the tool
  • Battery delivers consistent power and run time in extreme temperatures, even in winter (-4°F/-20°C)
  • Equipped with star protection computer controls to protect against overloading, over-discharging and over-heating
  • Impact-resistant outer case and shock-absorbing inner-liner are engineered to protect the battery
  • 16 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
  • Makita 18-Volt lithium-ion is the world’s largest cordless tool line-up powered by an 18-Volt lithium-ion slide-style battery
  • Makita technology delivers category-leading charge time so the battery spends more time working and less time sitting on the charger (charger not included)

Does this battery have more power than the 4.0

Asked by: Neff42
I'd love to be able to tell you that it does, but it doesn't! It just has the same power for a more extended amount of time! 2 Amp hours more time actually. That also means it will take longer to charge.

My BL 1815 battery won't fit in my new grinder. Apparently this battery or any other battery that doesn't have a B won't fit in the new tools. Why? I bought the grinder only without battery assuming my other batteries will work. Wrong. Does that mean if I buy the new battery that ends with B it won't work with my old charger, Model DC18RA. Why would Makita do this??
Asked by: Jimbo
This is a star battery your tool needs to be a star tool. That is my understanding of how it works Look to see if there is a star on the grinder

Rated 5 out of 5 by from Excellent battery for my new compact (Black series) 18V drill... Excellent battery for my new compact (Black series) 18V drill driver. The older 18V batteries are not compatible with the compact series so I had to purchase. These batteries work with older 18V series tools, but not vice versa.
