## Overview

The Makita BL1850B 18V LXT Lithium-Ion 5.0Ah Battery offers 65% more runtime than its predecessor with a rapid 45-minute charge time. Engineered with Star Protection Computer Controls, it safeguards against overloading, overheating, and over-discharging, ensuring extended battery life.

The built-in LED charge indicator provides real-time battery status, keeping you productive and in control.

## Description

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.

Review: Great Battery if You Own All "Star" LXT Tools, Makita Leaves You Some Tough Decisions if Not - 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.
Review: Genuine, worth the price. - 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.

## Questions & Answers

**Q: Are these oem makita batteries or after market batteries with the makita brand logo on it, logo looks odd small in size?**
A: I honestly had a similar concern when I purchased these, but I made a good gamble. these ARE without a doubt legitimate Makita Batteries. (I don't do after market) The label style tends to change ever so often, I think that is what accounts for the smaller label. I was quite pleased with my purchase of these batteries, work as well as all my other 5 amps do. best wishes.

**Q: Will the charger i use for my 3 amp makita batteries charge a 4 and 5 amp battery?**
A: Yes, as far as know they are all compatible. I've been charging mine for the last couple weeks without any trouble.

**Q: Will the charger I use for my 3 amp makita batteries charge a 4 and 5 amp battery?**
A: Yes. Works the same for all of them.

**Q: Is it worth to pay high price for makita battery instead of much cheaper alternatives?**
A: That is something you have to answer yourself, I have always bought the Makita branded batteries and haven't had any problems. I also wait and look for good buys on the Makita branded accessaries
