NiCad batteries use nickel and cadmium, while NiMH batteries use nickel and metal hydride. NiMH batteries have higher energy density and are more environmentally friendly than NiCad batteries.
NO, putting batteries in the freezer will not charge them. For alkaline batteries (the most common kind of household battery), putting them in the freezer will extend their shelf life by less than 5%. And cold batteries can't be used immediately -- you have to wait until they've warmed up to room temperature first. If you need those batteries for a flashlight in an emergency, this could prove problematic. When stored at room temperature, alkaline batteries retain 90% of their power, and the average shelf life of alkaline batteries is five to seven years. For NiMH and Nicad batteries (often used for electronics), storing them in the freezer might be more practical. These kinds of batteries lose their charge after a few days when kept at room temperature. But they'll retain a 90% charge for months if you store them in the freezer. Just like alkaline batteries, you'll need to wait until they've warmed up before using them. However, this isn't a problem when you need new batteries for your digital camera or other electronic gadget. Battery manufacturers tend to agree. Kodak says "refrigeration is not necessary, nor is it recommended" and "freezing is not recommended" for its alkaline batteries. Duracell advises: "Do not refrigerate Duracell batteries. This will not make them last longer." Both recommend storing batteries in a cool, dry place.
NiFe refers to nickel-iron, a type of alloy commonly used in the production of rechargeable batteries, such as nickel-metal hydride (NiMH) and nickel-cadmium (NiCd) batteries. NiFe batteries are known for their high energy density and long cycle life, making them suitable for applications such as renewable energy storage and backup power systems.
no difference just a name, kalef21; no, it has something to do with the chemical make up of it. i don't know what. the difference is the components creating the electricity. lead-acid is a non-alkaline battery because it uses lead and acid, not alkalai metals
A chemical battery is a battery with chemicals in it. Every electrical battery has chemicals which react to produce a potential difference (voltage) between the terminals. The term 'battery' actually refers to multiple cells (a car battery and 9-volt battery are examples). Most 'batteries' like AA, C, D etc only have one cell, but these are commonly referred to as batteries as well.
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
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.
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.
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.
No.
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.
No, you should not replace nickel cadmium batteries with nickel metal hydride batteries interchangeably in a device designed for nickel cadmium batteries. They have different charging requirements and using the wrong type can damage the device. It is important to follow the manufacturer's recommendations for battery type.
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.
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.
BTY AA NIMH Batteries: The BTY brand of NIMH batteries that are being sold on I had had received merchandise that matches exactly what they advertise.
Lithium Ion (LiON) batteries are lighter than NiMH batteries and also have no memory effect. They are more expensive, but worth every penny.
