Review title: Inconsistant
Product review: There seems to be different versions of this battery within the same part number, and I've yet to figure out how to tell them apart. Some of them hold a charge well (the older ones), others do not. If I didn't own 6 tools that use them, I'd never buy one again. I have 2 batteries that hold a good charge, even after being shelved for a couple days, others that must be charged before each use and run only for a few minutes. The different chargers also have widely varying degrees of effectiveness. If you do not already own tools from this system, I say to avoid it. I've done some research on this system, and B&D seems totally unwilling to divulge any information about how this system works.
