Review on Energup Li-Ion Replacement Battery Pack For Black Decker Versapak VP Series With 2-Port Charger by John Maynard

I have had the black and decker system every since it came out. Which is a long time. I have 2 drills, 2 lights, screwdriver, sander, saws and the wizard. I've up graded to the milwaukee system since but I still use the black and decker system for a few things. Batteries were becoming a big problem with the system but these batteries are working great. I have a 4 battery maintenance charger that they work in. They work in all the tools I have but some times I have to move the battery around to get it to work. I probable will buy another 2 pack so i have 4 in the charger at once. The have more power and last longer than the original versa pack extra life batteries.
