How do I rejuvenate a nicd battery?
The nickel-cadmium battery, or NiCd, is rechargeable and used for cordless power tools, portable toys and electronics, cameras, mobile cellphones and laptops. These batteries are available individually and in packs. Rejuvenating or recharging a NiCd has to be done carefully to prevent damage to the battery that would eliminate further use.Working with NiCd BatteriesThe best time to recharge your NiCd battery is when the device it’s in alerts you that the battery is low on power. At that point, it is discharged enough to be recharged without being damaged, which is called a full recharge cycle. Recharging this battery too soon will cause cadmium crystals to form in the battery, creating a “memory effect.” This effect “tells” the NiCd it is fully charged when it’s not, lowering the battery’s output efficiency. If the battery has an internal short circuit, a regular charge won’t rejuvenate it. That requires a high-current quick charge called “zapping” followed by a regular charge. Zapping
