This comprehensive guide provides a step-by-step solution to revive dead or weak NiCad batteries. It delves into the science behind NiCad battery degradation, specifically focusing on the formation of crystal dendrites that cause short circuits and prevent charging. The manual explains the "Revitalization through Vaporization of Dendrites" (RVD) process, a safe and effective method to restore NiCad batteries to full functionality. You'll learn how to apply this process at home, utilizing readily available materials and tools. The guide illustrates the RVD technique with clear diagrams and images, making it easy to follow even for beginners. It covers a wide range of NiCad battery applications, including portable phones, cellular phones, cordless phones, emergency lights, MP3 music players, PDAs, iPods, laptops, R/C devices, camcorders, cameras, digital cameras, two-way radios, cash registers, electrical toothbrushes, flashlights, torches, cordless drills, cordless shaving kits, cordless jigsaws, cordless saws, cordless hammer drills, hair dryers, routers, grease guns, reciprocal saws, laser levels, medical equipment, electrical toys, electrical gadgets, electrical grinders, electrical accessories, and many more. The guide also addresses issues with sealed batteries like Firestorm and Versapak, providing practical solutions for their revival. It helps you overcome common NiCad battery problems like no charge, weak power, inability to hold charge, complete death, and rapid power drainage. This DIY guide is designed to work with a wide range of NiCad battery brands, including A.E.G., Agatec, Alemite, All Power America, Black and Decker, Bosch, Bistitch, Buffalo Tools, Cox, Commercial Electric, Craftsman, DCM Tools, Delta, Drill Doctor, DeWalt, Dremel, ECHO, Fein, FesTool, Greenlee, Grip Rite, Harris, Hitachi, Hilti, Homelite, Husky, Hyundai, Ingersoll Rand, JET, Kreg, Kwilset, Lincoln, Makita, Metabo, Milescraft, Milwaukee, MK Diamond, Motorcity Tools, Panasonic, Paslode, Porter Cable, Porta-Nails, Pro Series, QEP, Ridgid, Ryobi, Ramset, Rotozip, ROBERTS, Sears, Senco, Skil, Snap-On, Stout, Universal Tool, Warn Works, Wilton Armtale, Workforce, Work Sharp, and many others. The guide highlights that while most NiCad batteries can be repaired without disassembly, some severely damaged batteries might require individual cell or crystal repair.
