How Do Solar Lights Work?

Solar lights function on the principle of the photovoltaic effect. It has three components- photo-voltaic solar panels, rechargeable batteries, and LED lamps. The panels absorb sunlight with the help of solar cells. These cells then convert the solar energy into direct electrical current which via a charge controller is stored in the solar batteries. A single solar cell can produce a maximum of 0.45 volts. The current generated depends on two factors- the amount of sunlight striking the solar panel ad the size of the cell.

What Kind of Rechargeable Batteries Do Solar Lights Use?

Solar lights are eco-friendly and budget-friendly infusion to outer lighting devices. These lights use internal rechargeable batteries as these batteries need no wiring. These 3 types of batteries are mostly used in solar lights:

1. Nickel-Cadmium Batteries

These AA-size batteries need be to replace in one or two years. The NiCads are best for outer solar-light exertion as they are robust enough. They have an extended life and quite a high power capacity. But there is a major con of these batteries, cadmium is considered toxic.

2. Nickel-Metal Hydride Batteries

These batteries have an extended life expectancy of around 3-8 years and they also allow higher voltage. Unlike NiCads, they are pretty attentive toward the ecosystem.

The NiMH batteries may become inappropriate or may ruin a few solar lights. Before choosing NiMH batteries, make sure to confirm that the solar light is capable to charge them.

3. Lithium-Ion Batteries

These batteries are very popular for green applications and solar power. Their energy density is twice tight in comparison to NiCads. Moreover, they also need compact maintenance. They have a short lifespan compared to the other two batteries and they are also highly vulnerable to temperature concerns.

Can I Use Energizer Rechargeable Batteries for Solar Lights?

Yes, you can use energizer rechargeable batteries for solar lights. Although the mass batteries will work well for a period of time but shifting to NiMH or NiCd rechargeable batteries for your solar lights will be a wise decision. They provide long-term performance.

Most solar lights come with very stubby and inexpensive mAh Nicad cells which when properly charged generate close to 1.2v. On the other hand, energizer rechargeable batteries like NiMH cells produce around 1.4v when properly charged. If your solar panels obtain proper light, these batteries will light up throughout the whole night. Now that you have acquired to answer of can I use energizer rechargeable batteries for solar lights, let’s further learn about AAA rechargeable batteries solar lights.

What are AAA Rechargeable Batteries Solar Lights?

After learning- can I use energizer rechargeable batteries for solar lights or not, let’s explore AAA batteries. The AAA rechargeable batteries have a longer lifespan and create less waste. They are also cost-efficient. Most AAAs have a capacity rating of 1,100 and they run at 1.2 V. The Geilenergy brand produces AAA rechargeable batteries solar lights. They have a pack of 12 batteries with 1.2V and 600 mAh. They use the power of sunlight to recharge and they are also very easy to install. Also, read How to Use Solar Panel Directly Without Battery?

What are Dangers of Using Non-Rechargeable Batteries in Solar Lights?

After learning about AAA rechargeable batteries solar lights, let’s learn about the dangers of using non-rechargeable batteries in solar lights-

• Permanent system failure: The alkaline batteries don’t have the capability of storing collected charge. In the future, this can lead to charging problems as well as irreversible system damage.
• Unreliable Performance: The regular batteries aren’t designed for solar lighting units and thus don’t expect a smooth performance from them.
• Terminal Corrosion: Regular batteries can corrode the battery terminal of your solar lights as these batteries drain rapidly. If the corrosion happens, the connection between the battery and its terminals can get disrupted which can block power from the battery to reaching the light.
• Warranty Cancellation: The warranty of the solar lights can be voided if you use the wrong batteries in them. Although, solar lights come with warranties these warranties don’t cover damage caused by wrong battery usage.

Moving towards green energy devices is an appreciable step. Solar light is one of the many devices present in the market. It has a certain system that helps its functioning and a rechargeable battery is a very important part of this system. Choose the best rechargeable batteries for solar lights from Kinsun 8-Pack Rechargeable Battery Solar Garden Light, Henreepow Ni-MH AA Rechargeable Batteries and the ones listed above, as per your requirements & safety recommendations.
