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 battery. ## Features - 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 - Makita BL1850B-2 18V LXT Lithium-Ion 5.0Ah Battery, 2/pk ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B015PVD9ME | | Amperage | 5 A | | Antenna Location | Vacuum Cleaner | | Battery Capacity | 5 amp_hours | | Battery Cell Composition | Lithium Ion | | Battery Cell Type | Lithium Ion | | Battery Weight | 29 g | | Best Sellers Rank | #12,804 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #78 in Cordless Tool Battery Packs | | Brand | Makita | | Customer Reviews | 4.7 out of 5 stars 3,913 Reviews | | Global Trade Identification Number | 00088381463928 | | Included Components | batteries | | Item Dimensions | 4.25 x 6.75 x 9.75 inches | | Item Type Name | Makita Battery | | Item Weight | 1.4 pounds | | Manufacturer | Makita | | Model Name | Makita BL1850B-2 18V LXTยฎ Lithium-Ion 5.0Ah Battery, 2/pk | | Model Number | 197288-2 | | Number of Batteries | 2 Lithium Ion batteries required. | | Recommended Uses For Product | Vacuum Cleaner | | Reusability | Rechargeable | | UPC | 088381463928 | | Unit Count | 2 Count | | Voltage | 18 volts | | Warranty Description | 3-year limited warranty | ## Product Details - **Battery Capacity:** 5 amp_hours - **Battery Cell Composition:** Lithium Ion - **Brand:** Makita - **Number of Batteries:** 2 Lithium Ion batteries required. - **Recommended Uses For Product:** Vacuum Cleaner ## Images ![BL1850B-2 18V LXT Lithium-Ion 5.0Ah Battery, 2/pk, Black - Image 1](https://m.media-amazon.com/images/I/61af+3pOl5L.jpg) ## Available Options This product comes in different **Style** options. ## 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.
