Makita BL1850B 18V LXT® Lithium-Ion 5.0Ah Battery

Description:

  • Integrated L.E.D. 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 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

  • The Makita 18V 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 4.0 Ah battery combines more run time (35% more run time per charge than the Makita BL1830 battery) with a category-leading charge time of only 40 minutes, so it spends more time working and less time sitting on the charger. For added convenience, it also features an L.E.D. charge level indicator to monitor battery charge. The 18V LXT 5.0Ah battery (BL1850) is compatible only with Star Protection tools, indicated by the Star Symbol and/or Yellow Battery Receiver under the tool. Makita 18V 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 cordless tool line-up powered by an 18V lithium-ion slide-style batteries.

    5.0 out of 5 stars Great Battery if You Own All "Star" LXT Tools, Makita Leaves You Some Tough Decisions if Not

    J.W. · July 11, 2016

    I have nothing but nice things to say about this battery. It is almost identical in dimensions and weight to the BL1830's, but adds an additional 2 amp hours of runtime, the battery capacity gauge, and Star protection. The battery capacity gauge works well. Activating it requires depressing a small push-button switch on the back of the battery. This is a plastic "bubble" style magnetic switch found on devices like kitchen timers. This style of switch is not the most durable, and seems to be the weak link in what is otherwise a very well-made product. So far so good, though, so perhaps this will not be an issue over the life of the battery. Star protection is Makita's name for an internal circuit that will not let you overheat the battery, or run the battery down to such a complete state of discharge that it cannot be recharged, which can be an issue with some lithium battery systems, like Makita's own BL1830 batteries.The best feature of this battery over an 1830 is the warranty: 3 years instead of just one. That makes this a pretty reasonable investment for any regular user. Also note that the additional capacity should mean fewer recharge cycles, and thus longer life.While I have nothing but nice things to say about this battery, I do have some less-nice thing to say about Makita. The Star protection is great, but they sold non-Star tools and batteries for a number of years, leaving a lot of customers such as myself with a significant investment in these products. While Star protection is marketed as a feature of the new generation of tools and batteries, a more honest evaluation would be that Makita sold a tool/battery system with a significant design flaw for quite a while. This battery represents what is essentially a totally different battery system. It looks the same, is still called "LXT," and uses the same chargers, but it is physically not compatible with the old tools without warranty-voiding modification. If you have non-Star tools, you can easily take a chisel to the small tab that prevents this battery from mating with them, and this battery will power them just fine. However, this modification definitely voids the tool warranty, and might void the battery warranty as well-- these batteries do contain a memory chip, and I have not been able to find any definitive information on whether or not they log interfacing with a non-Star tool. It also means that the battery will not be protected by the Star circuitry when using that tool.I am currently "playing it safe" and using this battery only with my Star tools. I'm not quite sure what I'll do if my non-Star tools outlast my dwindling BL1830 fleet. As much as I love my Makita tools, unless Makita offers some kind of trade-up program, I have a feeling that the solution might be yellow and black.

    5.0 out of 5 stars Genuine, worth the price.

    S.H. · November 15, 2025

    Seems to be genuine. Came in original package. Fits as expected. Charges within the 45mins as stated with the rapid charger. Weight alittle more than a 3amp. Will buy another soon.

    J.M. · August 4, 2025

    Used it with the Makita hedge trimmer and it did the whole job with charge left.

    5.0 out of 5 stars More power Same weight ... level up.

    Z. · July 17, 2025

    This 5 AH appears to be same size and weight as my old 3AH Makita battery that was starting to show weakness. I popped it in the charger and it was ready in about 45 min. Zero bars charge out of the box - but all topped off now. Gave it a try in the Makita circular saw and works well. Satisfied with my purchase. Haven't tested the power vs the 3AH nor the duration of the charge but I expect it to be excellent.Love the addition of the charge level meter - makes it easy to pick up and see if its ready to go. A little more than a Dewalt OEM 4 AH i got recently but still in the ballpark of what OEM's cost these days at around $80.Pleased with purchase ... I now have to be careful I don't go and justify additional Makita tools to use the battery.

    4.0 out of 5 stars They work as they should.

    M. · July 3, 2025

    4 starts only because mine was not sealed in original packaging. It was in a ziplock bag like the kind you use in your kitchen. No where in the description does it say this is a open item, returned, or refurbished item. so 4 stars. The price & quality of the battery saved this review.Battery looks new. No scuffs or marks showing use.Battery charged and works as it should. I tested it hard in my weed trimmer and it easily out performed my 4Ah OEM battery.Battery is identical to my expensive OEM Makita batteries. I cant tell any difference in any way.I Will buy more of these.Not sure why it did not come in OEM packaging. Not sure where these come from or if they are refurbished or open returns. They do perform as they should and the price is excellent.
