![]() Injuries law suites to follow, still cheaper than doing it right. I have worked with Asian engineering group, the learn fast but are still on the learning curve and even in that endeavor are hampered by the need to get the job done fast and cheap. places on Consumer Market supplier are certainly not conductive to attract the most skilled. ![]() I do not mean to demean the Asian engineers, there is no reason for being any less skilled that any other group.

Just yesterday the 6:00 PM news reported yet one more case battery ignition. Sorry! This is another case of caveat emptor. The charging-with-an-out-of-spec-voltage trick to revive a failing battery is a common one, and almost always results in a battery that will not hold a charge. You don't mention if these batteries are NiCad or lithium-ion (LI), but what you most likely have been sold are recycled LI batteries in a reconditioned case. Not one to rain on anyone's parade, but I believe you are the victim of a crooked seller. If your battery won't charge at all this is a simple way to get it to charge again. ![]() Over time these batteries lose their ability to charge fully and maintain a charge. ![]() I've seen videos of people zapping them with a higher-than-spec voltage, but that appears to be for batteries that are not charging. How to Make a cordless drill battery start charging again Cordless drills are powered by rechargeable batteries. Is there anything that can be done to "resurrect" them? Sounds like there is some kind of internal short draining them. If I charge them, take them off the charger and let them sit for a whole, when I go to use them, they have just a trickle left in them. They will charge, and if I use them out of the charger, they work great and work for a long time. SteveM wrote:I have some aftermarket replacement batteries for my 12v dewalt drill. ![]()
