Product overview
Black & Decker 18V 4.0Ah Lithium-Ion Slide Battery Pack for Power Tools - Black
The Black & Decker 18V 4.0Ah Lithium-Ion Battery Pack is designed to power compatible cordless power tools and garden equipment within the Black & Decker 18V POWERCONNECT system. Its rechargeable lithium-ion technology provides reliable cordless operation, helping users complete household repairs, DIY projects, and outdoor maintenance without relying on a mains power connection.
With a 4.0Ah capacity, this battery provides extended operating time compared with lower-capacity batteries in the same compatible system. The 18V output supports a range of compatible cordless tools, while lithium-ion technology helps reduce self-discharge during storage and avoids the memory effect associated with some older battery technologies.
