There are different types of rechargeable batteries available in the market each with their different characteristics and usage methods.
And because of such varieties, it’s natural for a consumer to get confused about which one to buy for their need and what type of services it would provide.
In this article, we have talked about the top 5 rechargeable cells in detail so that you can have a very basic idea about them and find it less complicated about buying a battery for your specific needs.
1. Nickel Cadmium (NiCd) Battery
The Nickel Cadmium is used when a high discharge rate, battery life as well as the price is taken into account. This means that Nickel Cadmium provides a high discharge rate and an extended battery life at a very reasonable price tag. Moreover, a NiCd battery is the only battery that can gain power ultra-fast reducing your waiting time to charge a battery fully. But remember to discharge this cell completely before charging it again as it is the golden rule to enjoy better performance and an extended life span.
This obsolete rechargeable battery uses nickel oxide hydroxide and metallic cadmium as electrodes to supply power to tools. It was invented in 1899 and was widely used in portable power tools, flashlights, photography equipment, emergency lighting, hobby R/C, and other portable electronic devices since then.
But with the good comes the bad. A Nickel Cadmium battery is not environmentally friendly at all due to the toxic metals incorporated in it and therefore, it is advised to not use this battery if you have any other options.
2. Nickel-metal Hydride (NiMH) Battery
Because of Nickel-Cadmium battery’s toxicity and its potential danger to the environment, in the 1960s, researchers developed the Nickel-Metal Hydride battery with almost 40% higher energy density level than the NiCds at a very reasonable price range.
The NiMH rechargeable batteries also have a similar composition as the Nickel-Cadmium batteries except the cadmium is replaced by hydrogen as an active material making these cells safe for the environment as well as you, and this is why the Nickel-Metal Hydride batteries are one of the most popular rechargeable batteries among users all over the world.
These batteries are available in AA, AAA, and other sizes and can be used in mobile phones, laptops, cameras, toothbrushes, razors, and other everyday items effectively.
But remember that you should not use a NiMH cell in any low energy drawing items it is not suitable for such items and might get damaged.
3. Nickel-Zinc (NiZn) Battery
In 1901, Thomas Edison invented the rechargeable Nickel-Zinc battery, which was then installed in the rail car to operate it without coal or other types of fuels. Even though this cell is not toxic and doesn’t impose any harm to the environment, the NiZn battery is still not popular among its users because of its high self-discharge rate; the cell will lose power and drain itself completely even when it sits idle, unused. Also, this battery comes with a very short life span which means that you will need to change the cell of your device frequently to make sure that it runs smoothly; continuous changing of cells is not only disturbing but at the same time also not cost-effective at all.
4. Lithium-ion (Li-ion) Battery
If you are looking for a rechargeable battery that is super lightweight yet comes with a very high energy density level, then the Lithium-Ion or Li-ion battery is the perfect choice for you. This cell was invented and developed by a group of scientists during the 1970s–1980s and commercialized in the 90’with the intention of providing users with a lightweight yet powerful battery for their portable electronic devices. A Li-ion battery can be used in cellular phones, laptops, tablet computers, wireless flat irons and other devices that require a battery to operate successfully. Made from lightweight lithium and carbon, the Li-ion cell has proved itself as the most promising battery in the industry to date.
Aside from its high power capabilities, the other reasons for favoring this over others are that a lithium-ion battery is an extremely low maintenance item and has a very limited self-discharging level compared to other rechargeable cells. Moreover, it is available in a wide variety of options so that you can easily buy the one that best fits your device perfectly.
5. Lead Acid Battery
Developed in the year 1859, the lead-acid battery is the oldest type of rechargeable battery available in the market. This type of cell uses sponge lead and lead peroxide to convert chemical energy into electrical power and has a very high cell voltage level.
Moreover, although this cell uses very old technology and didn’t change much since it’s invented year, it is still very popular and used widely even today.
One reason behind its popularity is that it is a very economical option and can be used to provide power in big facilities like power stations and substations. You can also use this battery in hospital equipment, emergency lighting, UPS systems, and wheelchairs.
But with advantages come the disadvantages; because of heavy metal elements of lead-dioxide cathode a sulphuric acid solution electrolyte, and a sponge metallic lead anode, a lead-acid cell is toxic and is not environment-friendly at all. Furthermore, this battery has the potential to cause a severe hazardous incident if you do not dispose of it correctly with caution.
