Makita BL1840B-2 18-Volt LXT Lithium-Ion High Capacity Battery Pack 4.0Ah with LED Charge Level Indicator (2-Pack)

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 4.0Ah battery， model BL1840B， 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 on-board LED charge level indicator to monitor battery charge. The 18-Volt LXT 4.0Ah 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.
