2-Pack HPB18 Replacement 18V 3600mAh Ni-MH Batteries - Longer Run

In this review the focus is on the 2-pack HPB18 replacement batteries that aim to revive older cordless Black and Decker tools and vacuums. The bottom line: these 3600mAh Ni-MH packs are for anyone who needs a reliable, higher-capacity swap for worn 18V Ni-Cd cells and wants longer run time without changing chargers or tool housings. They are best when compatibility and extended battery life matter most, and the review highlights real-world fit, charge behavior, and durability based on product specs and user feedback.

Key Features

• Upgraded Capacity: The 3600mAh Ni-MH cells deliver noticeably longer runtime than typical 2.0Ah Ni-Cd replacements, extending use between charges.
• Wide Compatibility: Designed to fit many Black and Decker 18V models such as HPB18, 244760-00, A1718 and a range of FS and NHT series tools, so it works across cordless vacuums and power tools.
• High Quality Cells: Built from higher-grade battery cells that the manufacturer says have no memory effect and can be charged or discharged as needed without capacity loss.
• Easy Installation: The pack is made to fit the original battery bay and installs quickly, making replacement straightforward for DIY maintenance.
• 12-Month Support: Comes with a 12-month quality problem solving period from the date of purchase for added peace of mind.

Who It's For

This pack is aimed at homeowners and hobbyists who own older 18V Black and Decker cordless vacuums or tools and want to restore reliable run time without replacing the entire tool. It also suits users who prefer Ni-MH chemistry for slightly higher effective capacity over older Ni-Cd packs.

Those who should look elsewhere include users who need a different voltage, a specific OEM-labeled pack, or who require advanced battery management features found only in branded smart packs. Also confirm physical fit for less common model variants before purchasing.
