BLACK+DECKER 18V POWERCONNECT 4.0Ah Battery w/Charge Indicator, BDL4018S-XJ

LONGER-LASTING CORDLESS POWER: The 18V POWERCONNECT 4.0Ah battery gives you more runtime for bigger DIY jobs, fewer charging interruptions, and the freedom to swap one reliable battery across compatible BLACK+DECKER tools, with a handy state of charge indicator so you always know how much power you have left. 18V POWERCONNECT COMPATIBILITY: This battery works across compatible BLACK+DECKER 18V POWERCONNECT tools, so if you already own one in the range, you can swap the same battery between tools for easier DIY, less clutter and better value. 4.0AH LONGER RUNTIME: A 4.0Ah battery stores more energy than a 2.0Ah battery, so you can work for longer between charges and get through bigger DIY jobs with fewer interruptions. STATE OF CHARGE LED INDICATOR: Built in battery lights show how much power is left, so you can check before you start and avoid the frustration of the battery running out halfway through a job. LITHIUM ION TECHNOLOGY: This modern battery technology delivers reliable performance and is designed for regular use, giving you dependable cordless power for everyday DIY tasks. 18V POWER SYSTEM: Because this battery uses the same 18V system as compatible BLACK+DECKER POWERCONNECT tools, it can replace a smaller 18V battery while simply giving you longer runtime. HIGH CAPACITY: This higher capacity battery is a good choice for more time-consuming tasks like repeated drilling, sanding, furniture assembly and outdoor tidy-ups, where a smaller battery may need charging sooner. CORDLESS FREEDOM AND FLEXIBILITY: Using a rechargeable battery means you can work without trailing cables, making it easier to move around the house, garden, shed or garage. EASILY REMOVABLE PORTABLE DESIGN: The battery is easy to carry, store and swap between compatible tools, which makes your DIY kit simpler to manage and more convenient to use. FREEDOM TO POWER UP: If you already own tools in the POWERCONNECT range, this battery is an easy upgrade from 2Ah to 4Ah - helping you get more done with the tools you already have, except for the BCD900 SDS Hammer Drill.
