Review: Works well enough for my B&D Drills, skill saw, and jiggle saw. - Seems good. They take a charge and work. They put out the same power, but have not measured the extra amp hours. I have multiple tools that take this battery. Only one of my drills needs a bit of force to seat the battery vs a legit B&D battery.
Review: Long lasting power - Excellent. I use these with the Black and Decker vacuum to give long life. Does take a bit longer to charge but a these 4000mAh batteries allow me to vacuum the whole house easily with one battery on a mid setting for the B&D stick 20v floor vacuum.
