Ni MH AAA Batteries: Anytime Energy Resource

Author: Lucy

Ni MH AAA Batteries are those used by us in our day-to-day life. Nickel metal Hydride cells evolved from Nickel Hydrogen batteries just two decades back. Like Nickel-Cadmium Batteries, Ni MH Batteries are also a secondary electrochemical battery and use oxyhydroxide on its positive electrode. The only difference is that it uses an alloy that absorbs hydrogen on the negative electrod, in place of cadmium.

They weigh only 14-15 grams. They have a capacity of 1.2 volts, that is, 1200-1500 mAh. Whether you use regular or rechargeable Ni MH AAA Batteries, it is important that they are used effectively to get the most out of them.



Qualities Of Na MH Battery

However, Ni MH Battery wins over other conventional batteries in many ways. At about the same voltage, it is about two times more energy efficient than a NiCd battery and therefore, lasts at least three times longer than its closest counterpart. These have many other advantages over other regular batteries, some of which are as follows:

*They are an energy resource, that is, they are environment friendly, as they do not contain harmful substances, such as mercury and cadmium. These are not thrown or disposed of after use, thus reducing the burden of chemical waste.
*They are rechargeable. These can be repeatedly charged and reused after they get discharged. They can be charged for about 500 cycles.
*They do not overcharge or over discharge like other batteries.
*They discharge easily due to low internal resistance.
*They can be charged very quickly. It takes a little over an hour to completely charge them.
*They can reuse energy that has not been used. This makes then energy savers too.

Uses Of Ni MH Cells

AAA Ni MH batteries are mostly utilized in electronic appliances, such as remote controls, cordless phones, electronic toys, torches, stereo systems, portable radios and MP3 players, digital cameras, electric tools, and the like. These are perfect for digital products. In this era of technology, people are a lot dependent upon various appliances. These batteries are a must for proper functioning of the equipments.


Low Self-Discharge

Most of the leading battery manufacturers are offering a more efficient version of Ni MH AAA Batteries. It is known as low self-discharge nickel-metal hydride battery or LSD Ni MH battery. It uses enhanced positive electrode and improved separator. It increases efficiency by reducing the self-discharge. This property of LSD Ni MH battery increases its shelf life and also its capacity by 70-85 per cent. These kinds of batteries are useful for appliances or gadgets that use high energy.

Since Makita Ni MH Batteries are rechargeable, they can be used over a long period of time. Thus the slightly higher cost is completely justifiable and worth each penny. It also saves the hassle of carrying extra batteries while on the move. All one needs to carry is the charger for the Ni MH AAA Batteries, and they can renew their energy resource anytime.


Ni MH AAA Batteries have great potential and are used in all modern appliances, as they last longer and can be recharged. New improved versions promise more to the users.
