Must be ok as they are frequently used in Alarm bell boxes exposed to cold weather.
Nicad is short for nickel-cadmium
Yes,
Typical D cell batteries NiCad or otherwise are 1.2 volts.
Nicad batteries have sodium hydroxide electrolyte. Citric acid powder will neutralize it.
you can change the nicad batteries for nimh without any problems, the charging will take longer as the capacity of the nimh batteries will be much higher than the nicad batteries.
Yes, in nickel, metal, hydride and NiCad.
That is nicad, pertaining to batteries.
It depends on if it is a Nicad or lithium ion Battery Lithium Ion batteries are ruined if they become completely discharged. Nicad batteries can be partially brought back to full service by placing in the deep freeze over night and allowing to defrost then re charging. Nicad batteries also work best if the battery is discharged all the way and then re charged slowly. If you are talking about the battery case used on drill motors, take it to a battery store. They will open it up and replace the C batteries inside. Generally this is far cheaper than buying a new battery.
NiCd Nickel & Cadmium
You cannot do that. When dead, they are gone for good.
In NiCad batteries the negative electrode is made of Cadmium, while in NiMH batteries it is made of an intermetallic compund, consisting of a rare earth (such as Lanthanum or Cerium) and a transition metal (such as Manganese or Nickel). anonymous@oola.com
Yep. This type of battery is most famous for suffering from the memory effect, which is one of the reasons for why NiMH batteries have largely replaced them.
