Makita BL1840B 18V LXT 4 Ah Lithium-Ion Battery

Details
Makita continues being the innovation leader in cordless tool technology, expanding the world's largest 18V Lithium-Ion cordless tool platform with the BL1840 18V LXT Lithium-Ion 4.0 Ah Battery Pack. The new battery is engineered for more run-time and faster charging than other 18V 4 Ah Lithium-Ion batteries on the market today. You can now depend on 35% more running time, and a full recharge of only 40 minutes, which is twice a faster rate than the competition. An impact-resistant outer case and shock-absorbing inner-liner will survive the demands of a harsh work environment, delivering power in the most extreme hot and cold weathers. STAR Protection Computer Controls allow the tool and battery to monitor conditions during use and exchange data in real time to protect against overloading, over-discharging and overheating, and will communicate with the Rapid Optimum Charger to optimize battery life by actively controlling current, voltage and temperature. With over 80 items in the lineup, Makita has again extended its line of 18V Lithium-Ion tools to give you unmatched breadth-of-line, power and efficiency.
Features:
  • Reaches a full charge in only 40 minutes which is two-times faster than leading competitors in its class
  • Fully compatible with 18V LXT and 18V Compact cordless tools that carry the star symbol
  • Up to 35% more run time than the Makita 18V LXT Lithium-Ion 3 Ah battery
  • Battery delivers consistent power and run time in extreme temperatures, even in winter
  • Impact-resistant outer case and shock-absorbing inner-liner are engineered to protect the battery
  • STAR Protection Computer Controls allow the tool and battery to monitor conditions during use and exchange data in real time to protect against overloading, over-discharging and overheating
  • Communication with the Makita Rapid Optimum Charger (sold separately) takes place with the battery's built-in chip throughout the charging process to optimize battery life by actively controlling current, voltage and temperature

Unusual awesome customer support and pricing
Very happy with my purchase, the battery was delivered on time and as advertised, there was a computer hiccup on the order but customer service resolved the issue with a level of professionalism and care unheard these days. I would definitely buy from these guys again.

If Makita makes it, it has to be great. I've not used the battery yet, but it's a Makita product, what else

Is this battery the same shape as my 3.0 Ah battery?
Tom C on Jul 9, 2017
BEST ANSWER: The 3, 4, & 5 Ah batteries are all basically the same. The only issue you might run into is that some have a star symbol on them and my guys have told me that there's a little plastic tab they have to break off so that they work with older tools without the star label.

Makita LXT Lithium-ion Tool Warranty

Every Makita® Lithium‐Ion Power Tool is thoroughly inspected and tested before leaving the factory. If you are not satisfied with any Makita Lithium‐Ion tool within 30 days of purchase, return it and Makita will provide, at Makita's option, a replacement or refund. Each Makita Lithium‐Ion Power Tool, Battery and Charger is warranted to be free of defects from workmanship and materials for the period of THREE YEARS from the date of original purchase. Should any trouble develop during the three‐year period for the Lithium‐Ion Power Tool, Battery and/or Charger, return the COMPLETE Power Tool, Battery and/or Charger, freight prepaid, to one of Makita's Factory or Authorized Service Centers.

If inspection shows the trouble is caused by defective workmanship or material, Makita will repair (or at our option, replace) without charge. This warranty does not apply to Makita Accessories, like flashlights.

This Warranty does not apply where:

  • Repairs have been made or attempted by others
  • Repairs are required because of normal wear and tear
  • The tool has been abused, misused or improperly maintained
  • Alterations have been made to the tool

  • In no event shall Makita be liable for any indirect, incidental or consequential damages from the sale or use of the product. This disclaimer applies to both during and after the term of this warranty. Makita disclaims liability for any implied warranties, including implied warranties of "merchantability" and "fitness" for a specific purpose, after the three-year term of this warranty. This warranty gives you specific legal rights, and you many also have other rights which vary from state to state. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you.
