Review on 🔋 Powerextra 2-Pack 3.7Ah 18V HPB18 Replacement Battery – Compatible with Black and Decker HPB18 HPB18-OPE 244760-00 A1718 FS18FL FSB18 Firestorm 18 Volt Battery by Vedprakash Trilltight

Two upgraded batteries. I'm not exactly sure what the capacity of the original B&D tool batteries is, but they appear to be much larger. I have a drill and a blower. The blower with a new OEM battery can run for 15 minutes, enough to blow off the track and track after mowing the grass. This battery was still working after covering twice the area and took very little time to charge, so I'm guessing it had plenty left over. I haven't used it much for a drill, just some small projects. But I never felt like I lost charge. I may feel different over time, but for now I think this is a BIG addition to my B&D toolbox.
