Ni-MH battery is an early alternative to nickel-cadmium battery

Nickel-cadmium batteries: (Ni-Cd, Nickel-Cadmiun Batteries

, Ni-Cd Rechargeable Battery): Nickel-cadmium batteries Battery laptop battery were the first used in mobile phones, notebook computers, and other battery types, it has good high-current discharge characteristics, overcharge discharge capacity, easy maintenance. Nickel-cadmium battery is fatally flawed, in charge and discharge process, there will be serious "memory effect", so service life shortened. The so-called "memory effect" is the battery charge before the battery has not been completely exhausted, the battery capacity over time will lead to the reduction of the battery during charge and discharge (discharge more obvious), will produce a little battery plates small bubbles, these bubbles accumulate and reduce the size of the battery plates also indirectly affect battery capacity. Of course, we can control the charge and discharge reasonable way to reduce the "memory effect." In addition, cadmium is toxic and therefore not conducive to nickel-cadmium batteries to protect the environment. Many shortcomings make nickel-cadmium batteries have basically eliminated the application of many sectors of the battery. Nickel-cadmium batteries with the positive retail packaging into convex head and flat head assembly packaged with the positive two, there was no difference in capacity. Nickel-cadmium battery memory effect than Ni-MH battery to the grave. Therefore, it must be carried out completely when not charging, to ensure that the service life.

Ni-MH Battery (Ni-MH Batteries): Ni-MH battery is an early alternative to nickel-cadmium battery, which is the most environmentally friendly battery, no use of toxic cadmium, can eliminate the heavy metal pollution on the environment. Ni-MH batteries have greater energy density ratio, which means you can not add extra weight for the device context, use nickel-metal hydride batteries could extend the equipment's working hours. Another advantage of NiMH batteries: nickel cadmium batteries greatly reduces the problem of "memory effect", which makes Ni-MH battery can be more convenient to use.

Nickel metal hydride batteries and nickel-cadmium batteries are similar shape, and nickel-metal hydride batteries and nickel-cadmium battery cathode basically the same, are based on nickel hydroxide as the cathode, the main difference is that nickel-cadmium batteries is cadmium negative electrode active material used, but Ni-MH battery based energy storage alloy as negative electrode, the nickel-metal hydride batteries with more energy. At the same time in the electrochemical characteristics of Ni-MH battery with the nickel-cadmium batteries are also similar, so when using NiMH batteries can completely replace the nickel-cadmium batteries.

Introduced the use of nickel-metal hydride battery of new products accelerated procurement of all heat, of course, her unique "qualities", such as energy density, charge more often, memory effects are small, the absence of mercury cadmium and other harmful metals series of advantages and Acer aspire 3613wlmi battery Travelmate 2414wlmi battery Acer batcl50l battery

achievement of the Ni-MH battery position in the market rising.
