What is the difference between Ni-Cd, Ni-MH and Li-Ion battery? What is the difference between Ni-Cd, Ni-MH and Li-Ion battery? Li-ion battery (lithium-ion). This is one of the new & 39; types of cells. It is the lightest batteries currently available on a commercial basis and can have more energy than most other types of cells. It knows no problems with memory & 39; effect of this type of battery and it is the easiest type of battery. L & 39; disadvantage of this battery is & 39; that the greatest genius costs and thus the prices are usually much higher than d & 39; other cell types. Ni-MH batteries (nickel-metal hydride). This type of cell is the most common type of the currently available for notebook computers (although Li-ion battery is the most popular). These batteries are relatively cheap to produce and, therefore, a tendency to be less costly that the Li-ion battery. This type of cell is dependent on the effect & 39; memory, it is therefore important to the maintenance of the battery Ni-MH batteries for & 39; n ensure that you have the best Runtimes. Ni-Cd (nickel-cadmium). C & 39; l & 39; is one of the oldest types of cells, and is generally older, is not only in the cell. The main pro for this type of cell is his ability to ever higher, and it is therefore more common in the electric tools or portable devices, which & 39; need a lot of energy to run efficiently. The biggest drawback of this type of cell is only & 39; is notorious for suffering l & 39; memory effect, no precautions must be taken with this kind of stack, in order to ensure optimal use of the battery.
