Nickel-metal Hydride (NiMH)
Over the last few years, nickel metal hydrate batteries have stormed the battery market due to their reliability and cost efficiency. They have a wide range of applications; from domestic appliances to industrial gadgets and have easily become the best rechargeable batteries on the market. You do not need to buy an additional pair of batteries once these are exhausted. All you need to do is plug into a battery charger and have then re-energized. This will not only cut down the ultimate cost, but are also environmentally friendly since you’ll hardly need to dispose them.
Nickel metal hydrate batteries, popularly abbreviated as NiMH, are a common type of secondary electro-chemical battery. This type of cell is quite similar to the nickel-cadmium cell although they have different chemical compositions. Nickel metal hydrate batteries are made of permeable hydrogen alloy as the negative electrode as opposed to the nickel cadmium which uses nickel oxyhydrate. Essentially, nickel metal hydrate batteries are considered to be more powerful compared to the same size of nickel cadmium batteries. Consequently, they are considered the best rechargeable batteries on the market.
The best rechargeable batteries and chargers are widely available in several retail stores under different trade names such as Duracell, Energizer, Eneloop, Energy16 and Ravoyac, among others. They are also available in common sizes of AAA and AA. However, a number of adapters are commonly available in AA size, C and D applications. Nickel metal hydrate batteries have a wide scope of use. These NiMH cells are commonly used in electric vehicle battery cells, rechargeable batteries for domestic electronics, remotes, toys, shavers and flashlights among other applications. A number of digital cameras and other devices that require powerful energy charge source use Nickel metal hydrate batteries.
Nickel metal hydrate battery cells are cheaper considering that their electrical energy and performance is the same as the primary alkaline-based cells of equivalent sizes. In fact, the best rechargeable batteries can be substituted for most applications. While most alkaline-based batteries are rated 1.5 volts and Nickel metal hydrate battery cells at 1.2 volts, voltage eventually drops below that of Nickel metal hydrate batteries during discharge in alkaline. In addition, Nickel metal hydrate battery cells do not get weak even when a higher current is drawn during use. This is because the batteries have lower internal resistance.
Although many of the specifications will remain similar when purchasing nickel metal hydrate batteries of different manufacturers, the value of service may vary. For instance, while some nickel metal hydrate battery products will have a charge life of up to 2 years, others will rarely give you a service of 6 months. Therefore, it is important to be aware of the fact that, in as much as nickel metal hydrate batteries are worth having in your appliance, not all products will give you similar results regardless of whether they are rechargeable or not.
Another thing you need to keep in mind is that different appliances will have different requirements as far as battery specifications are concerned. Remember, nickel metal hydrate batteries come in different sizes, shapes and charge output. Hence, it is good to understand the requirements of the gadget that need the battery. Also, carefully follow charging instructions of the battery.
Overall, the Nickel Metal Hydrate batteries are considered among the best rechargeable batteries in the market. Purchase a pair and you will be glad you did.
