Illuminating outdoor with solar lights is an amazing idea and I think most of you have thought about this as well. Now before you get too excited and purchase a bunch of solar lights to illuminate the garden or the pathway, you need to make sure that you understand the inner mechanism. Believe it or not, batteries do play a crucial role here. Most solar lights come equipped with solar panels. These solar panels are then placed under direct sunlight and once they get exposed to sunlight, they start generating electricity. This electricity will then get stored in the batteries. Now, as the sun goes down, these solar lights lit up automatically and they start drawing power from the stored solar energy from their batteries.
So, the performance of the solar lights is directly associated with the quality of the battery. If the batteries are of low quality, they might not be able to supply power directly to these solar lights for long and thus it will defeat the very purpose of having solar lights in the first place. Finding the right batteries for a solar light is not complicated but there are definitely some steps involved. To make your job easier, here we have listed some of the best and the most popular batteries for solar lights –

How Do Solar Batteries Operate?
Solar batteries constitute an integral part of solar lights. They are designed for storing solar energy, which is then converted into electric currents for powering the lights for illuminating spaces.
Now, in batteries, the cells are the focal power units; they are composed of two electrodes and one electrolyte. Also, within cells, negatively-charged electrons (anodes) and the positively-charged ions (cathodes) are formed using crystalline silicon and chemicals.
In the case of solar-engineered lights, first, the solar panels absorb sunlight, which is then stored in cells. Thereafter, the anodes start shifting until they reach the cathodes. Due to these chemical reactions, the formation of electrons ensues alongside the anodes.
Next, the electricity generated gets stored in a battery after cathodes start transmitting electrons through the wires. When night falls, the batteries help in producing electricity for the solar lights to shine bright.
Similarly, upon the battery getting connected to solar lights, chemical reactions start to occur. Consequently, the electrons and ions begin flowing smoothly. Normally, electrons move faster towards the positive electrodes via the outer circuit.
As long as the solar panel receives adequate sunlight, the charging and storing processes of a battery repeats daily. Besides, the ability of the cells to get charged depends on their location.
Types Of Solar Light Batteries
Different batteries are composed of varied chemicals. Here, we have listed some cells that are suitable for inserting in solar lights.
Nickel-Metal (NiMH) Hydrate Battery
NiMH batteries are inserted in solar lights, among other cordless devices. They are deemed safer than NiCd batteries; the latter poses hazardous effects to the surrounding environment if not disposed of properly.
NiMH batteries can are chargeable 500 to 1000 times, spanning 2 to 3 years. Only you should use them frequently for them to last longer.
Nickel Cadmium (NiCd) Battery
These types of rechargeable cells are commonly used in small-sized and portable devices. These include solar lights, cameras, toys, and computers. Using electrodes, they store energy. Such electrodes are constituted of an alkaline-based electrolyte of potassium hydroxide, metallic cadmium, and nickel oxide hydroxide.
The distinctiveness of NiCad batteries lies in the fact that they linger at 1.2v voltage until they run out of power. Therefore, they are effectual for supplying full power. NiCad batteries can last up to 1000 cycles before dying out and requiring replacement.
Lithium-phosphate batteries (LiFePO4) are a kind of lithium-ion batteries; though, they are upgraded versions. Their voltage drop is lesser than Li-ion batteries, because of which they are favored by those groups who need batteries which do not depend on voltage circulation circuitry.
If you’re thinking of purchasing them for your solar light requirements, then note that they make lights shine brighter and for longer – including when they are almost running out of power.
Lithium-ion (Li-ion) Batteries
The Li-ion batteries are other types of rechargeable batteries. They were popular during the 1990s. They come with double energy density as compared to Nickel Cadmium. Moreover, Li-ion batteries are lightweight with slender bodies.
