Product Overview

  • 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

Questions & Answers

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

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.

18-Volt LXT Lithium-Ion High Capacity Battery Pack 5.0Ah with LED Charge Level Indicator (2-Pack) is rated 4.6 out of 5 by 1354.
Rated 5 out of 5 by from Great addition to LXT system! I had heard about this 18V cordless oscillating/multi tool coming from Makita for a little while. When I finally saw it in stores, I jumped all over it. I've been using their LXT tools for close to 6 years, and can't imagine using anything else. While it is a little thicker than some electric models, that's to be expected to give the tool balance with the weight of the battery. It's certainly not too big to control, though. I love that it comes with the 2 adaptors, so I know no matter what blades I come across, I can make them work in the tool. The on-tool wrench storage is handy. As far as performance, I'm more than pleased. As long as you don't expect it to run all day on one battery, you'll be more than fine. I have the Makita electric multi-tool and find I hardly ever grab it now, since this can go anywhere. Makita might have been late to the game with their multi-tools, but they were worth the wait. They run quiet, cut fast, and have way less vibration than even the most expensive ones out there.

The various online reviews will tell you the standard types of things a multi-tool can do. But you won't really know how useful it is until you've got one. Today I used mine to cut a hole in a plastic goose. Never saw that use mentioned! But don't know how I would have done that without this tool. I'm finding myself using it almost daily for all kinds of weird things. Getting this one is a no-brainer if you already have other Makita 18v tools.

I bought one of these about 3 years ago and returned it after one day of use. It didn't last for more than 5 minutes on a full charge, tried 3 different batteries. I needed it again today and decided to give it another shot. Bought a new one, put a half charged battery in it right when I got home and cut through old cast iron and brass pipes clogged full of rust and hardened gunk that took forever to cut. Then I cut all my PVC and it was still going strong. I either got a dud the first time around, or they improved the saw. Note that the battery I used was one of the same ones I tried with the previous saw 3 years ago, still going strong! Happy with the purchase this time around! By the way, the metal blade that came with it is not that great. Milwaukee 'Torch' blades are worth every single penny. 4/5 stars because I need to use it for a while at work and see if continues to hold its own. Will update (if I can) after a while of use.

But these are amazing. I have yet to have a project that I have ran these 5ah to even half. I wish I would have bought them a long time ago. I love the push bottom power indicator. The 5ah are only 1/2 longer than the 2ah batteries and the weight difference is minimal.

I returned this after using it for 5 minutes. 1) The trigger release that allows you to pull the trigger is too small, too hard to push and is away from any reasonable finger to operate. I have large hands but could not use the release the trigger and operate the saw without using both hands. One for the trigger and one for the release button or trigger lock. I needed a third hand to hold the front of the saw firmly. Very poor design. 2) The trigger needed a lot of finger strength to keep it running at full variable speed. It would slow down and I could not figure out why until I realized that my finger had relaxed slightly. It took lots of concentration and finger strength to keep the saw running. I am sure that after using it for a while, the finger would fatigue. 3) Terribly under powered. I was cutting foam sheets 4 inches thick. This is a light and porous material. Easy to cut. However, the saw labored at times. I had a 5mah, fully charged Makita battery. Pros, it was cheap and light.

I purchased this after researching multiple manufacturers and looking at different upcoming deals. Was able to get this combo (2 drills and 2 batteries) along with an additional 5Ah battery for free which was the tipping point over the Milwaukee. It's probably overkill for average DIY home person as the 2Ah batteries would probably suffice but I sold the 5Ah so my total cost was really cheap for two drills and two batteries!
