Power Up Your Black & Decker Tools with KINGTIANLE 2-Pack 20V Batteries

This KINGTIANLE 2-pack brings you a pair of 20V lithium-ion batteries with a generous 4000mAh capacity. If you’ve ever paused a project to swap batteries, this kit is designed to help you keep going longer between charges. While results depend on your tool and workload, you may enjoy noticeably longer runtimes compared with standard 20V batteries, with roughly 2.5x more energy in favorable conditions.

Built for practical, real‑world use, the batteries deliver consistent power delivery and safe operation. The lithium-ion chemistry keeps weight manageable and supports comfortable handling during overhead work, tight spaces, or extended sessions in the garage or workshop.
