About This Product

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.

          Buying Makita 18V LXT batteries from an authorized dealer is the only way to insure you are getting genuine Makita batteries. Be careful, poor quality Makita-look-alike counterfeits are being sold online. Home Depot has the lowest price you will find for the 2-pack LXT 6.0 Ah batteries. Fast shipping. Makita factory-sealed clear-plastic 2-pack. Thank you, Home Depot, for a great deal. 5-stars !!!

          1 defective after 2 months of use
          I am an avid Makita fan. Over the years i have consolidated all of my tools to one brand, and chose Makita. I like the wide array of tools selection, the promotional deals they run from time to time, and the look & feel of their tools. However, i am disappointed in the latest batch of batteries i had received. After limited use and only a couple of months it is already blinking with an error code and will not hold a charge. I am hoping to have this replace under warranty but i have not reached out to Makita yet.

          Nice saw! Reliable, versatile, and powerful.
          Nice saw! This lightweight cordless circular saw packs a punch with its 18V LXT Lithium-Ion battery. Perfect for quickly cutting through various materials, making it ideal for DIY projects or professional use. The 6-1/2 inch blade is just right for most cutting tasks, and the LED light illuminates the workpiece in dimly lit areas. The tool is easy to handle and maneuver, making precise cuts a breeze. Overall, a must-have for anyone looking for a reliable, versatile, and powerful cutting tool.

            Great Batteries that Last a Long Time
            I am impressed with how long these 5ah batteries last. If you only have these two you will be able to charge one full before the other ones needs charging.

              Hope the new BL1830B last 5 years like old BL1830
              Purchased a brushless XRJ07ZB reciprocating saw. Purchased BL1830B-2, 2 pack of 3.0 amp hour batteries for $99 before tax. My 5 year old batteries still work. New batteries fit older LXT cordless ☆ tools. Similar numbers. New battery has indicator LED

                Couldn’t recommend the 5.0 Ah batteries more. Although they are heavier- suck it up, it builds muscle ;). I love that I can count on the quick charge time and how long each battery lasts. Depending what tool, I can go 2-4 hours on one battery using constantly. I now have three of them and watch for deals. I couldn’t be happier.
