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
Yes, as long as you use an NiCd charger, but you really shouldn't. NiMh has twice the capacity of NiCd and it is less expensive. NiMh also contains no toxic materials so it is better for the environment.
I talked to an expert at Total Battery and he said "yes, you can substitute NiMh batteries instead of NiCad, and still use the same charger." I dug up one of my old dead NiCad AA batteries and it's the same voltage as the AA NiMh battery. Ray B.
The NiMH battery is better,but it's more expensive.
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.
All rechargeable batteries develop a "memory effect", which occurs over time. This effect limits the ability of the battery to recharge close to its fullest potential charge. How quickly this problem manifests itself can directly depend on the discharge/charge cycle of the battery during its lifetime. It is always best to discharge a battery completely - or close to it - before recharging it. NiCAD and NiMH are older types of batteries where NiMH had more resistance to the "memory effect" than NiCAD. Hence, NiMH was a breakthrough in battery technology once upon a time. Now we have LiION batteries that are a major improvement over the NiMH batteries.
A NiCad charger has different sensor values than NiMh. I would find a charger that has a switch to select either, or specifically a Nickel Metal Hydride battery charger to prevent damaging and shortening the life of your batteries.
LI is better. And also NIMH does not have enough power as LI. LI is very powerful and will last longer than LI. LI is better in many things so it will work.
Some will, but it is not recommended because it can damage the batteries or the charger. Invest in a NiCd charger or better yet get some NiMh batteries. NiMh batteries are better than NiCd in every way.
It is always better to use a charger designed to charge a particular battery type. Using a NiCad charger for NiMh batteries or vice versa can cause damage to the charger or batteries, especially if the charger is designed to charge the batteries in under two hours. The worst case is a fire risk. Some charger and battery combinations will work perfectly well together but it is safe to assume that the charger will only be suitable for the battery types stated on 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.
GP nickel metal hydride batteries are a great choice for a rechargeable battery. Unlike the nickel cadmium alternative, NIMH batteries tend to have a longer life span. They do not need to be fully charged to retain their maximum charging potential. GP brand batteries also are an economical choice for the budget. Priced less than the competition, the NIMH battery is great for any item that is used often.
