One of the ways to power outdoor solar lights is to use the best rechargeable batteries for solar lights. Outdoor solar lighting is an eco-friendly way to light up your compound. Most people all they know is that solar harnesses solar energy which is later used to light the solar lights. But why do lights continue working even without sunlight?
The solar has internal batteries that store energy after the solar is exposed to the sun. When the sun sets or is low, the stored energy in the batteries will illuminate your compound.
The positioning of the solar to get full exposure to the sun is key. This is important, but it also depends on the batteries in the solar. The type and condition of the batteries determine how long the solar needs sun exposure.
Some batteries need four hours of sun and it will offer to light the entire night. Others may need a complete day of sunlight. This article will look at the best rechargeable batteries for solar lights. Buyers guide and answer some questions that you may have concerning rechargeable batteries for solar lights.

Factors to Consider When Purchasing Rechargeable Batteries for Solar Light

Chemical product
Different rechargeable batteries have different chemical compositions. Some of these chemicals include lithium-ion batteries, nickel, cadmium, lithium, and iron batteries. Each of these battery chemical compositions provides a different performance and function. Lithium-ion batteries, when used for solar lights, provide high-value operation and performance. There are other, more environmentally friendly batteries. Look for batteries without toxic components, hence taking care of your health.
Battery size
Battery size and type is an important feature to consider before purchasing rechargeable batteries. Different types are measured in A, AA, AAA, and other units. The different sizes are compatible with different devices. For solar light, the most common size in rechargeable batteries is AA.
The feature is vital as the batteries are used in different devices such as remotes, toys, game controllers, and sound devices. Look for rechargeable batteries that will serve your solar light and other devices.
Battery power capacity
This is the most sought feature of rechargeable batteries. The power capacity of a rechargeable battery is interpreted as its life span. The capacity of a battery is measured in Ah or mAh. Most rechargeable batteries have a capacity that ranges from 600 mAh to 100.
The life spans of batteries differ. Each life cycle offers greater energy capacity. Hence, it will save you time and money from buying new rechargeable batteries after a short period than what you expected.
Solar lights with long-life rechargeable batteries will offer high performance all night. You will be in a better position when you buy high battery capacity for your solar lights and other devices.
Energy efficiency

The energy efficiency aspect of a rechargeable battery is important to consider. Rapid energy recharging can offer high performance with less energy required to do so.
Since solar lights use solar energy to operate, the best rechargeable batteries will be those that take four to five hours to charge completely. When the sun intensity lowers, the implements will have the power to run the lights.
Energy efficiency can be analyzed in terms of how the batteries can prevent power loss while not in use. When batteries stay for a long time without being used, the maximum capacity loss can be reduced. This means when self-discharging is low, you can use the rechargeable battery after being stored for years.
Effectiveness against other factors
While these rechargeable batteries are used in solar lights, climate, and weather changes can affect their operations and performance. The temperature may rise and the batteries should not melt under these high temperatures.
When the temperature falls very low, the batteries should not be destroyed. Rechargeable batteries should be durable over different temperature ranges, making them adapt to different environments.
FAQs:
What kind of batteries do you use for solar lights?
AA batteries are mostly used for solar lights. They can be NiMH or NiCd type. The number of rechargeable batteries in a solar light depends on the design, but the common ones use four batteries. NiMH batteries have a high performance in cold weather compared to NiCD batteries.
Can regular AA batteries be used in solar lights?
It is not advisable to use regular AA batteries in solar lights. The reason is regular AA batteries have a brief life and will serve you for a moment.
Solar lights need rechargeable batteries that can recharge during the day and store some energy. The stored energy is used at night. So go for rechargeable batteries to power your solar lights.
How long do rechargeable batteries last?
How long a rechargeable battery serves you at optimum capacity will depend on the recharging cycle rating. Different batteries have different recharging cycle ratings. If you have a battery with a rating of 2000 cycles, it can serve you for years while a 500 rating can last for less than a year.
