Everything you need to know about battery lights 2022

As more individuals switch from traditional illumination to solar lighting, battery lights have become all the rage. Solar battery lights are the solar lighting system’s most critical component. Thus, you should educate yourself on the technicalities involved before buying one. Given the large range of battery types and capacities available on the market, buyers may have trouble settling on the best option. With that in mind, this comprehensive guide will provide you with all the information you need to make an informed selection of battery lights.

How do solar battery lights work?

Lighting-emitting diodes (LEDs), photovoltaic cells, rechargeable batteries, and charge controllers are the four primary components of solar battery lights. Batteries have two electrodes—an anode and a cathode—housed inside a plastic or metal case. The photovoltaic process describes the chemical reactions that occur at these electrodes when light hits the solar cells. All solar lights use photovoltaic cells, which convert sunlight into electricity. When placed in direct sunlight, electrons with a negative charge migrate to the anode, while those with a positive charge head to the cathode. This generates a current that is collected by batteries.

The battery light is designed to store energy for later use. When there is no sunlight available to power the solar lights at night, the energy stored in the batteries is used. The majority of solar light batteries are constructed utilizing a high deep discharging performance gel electrolyte technology. The use of nickel-metal halide, nickel-cadmium, and lithium, in addition to lead-acid, is commonplace among battery makers. Moreover, the battery management system helps to manage the rechargeable battery. So, it is important to use a battery management system to use a solar battery light efficiently.

Types of solar light batteries

Solar battery lights come in a variety of styles, each with its own set of pros and cons. You need to do some serious digging into the many possibilities and comparisons to find the one that works best for you. The various battery options are as follows:

Lithium-ion solar battery light

Although the idea for Lithium-ion batteries was developed in the ’80s, they didn’t enter widespread use until the ’90s. Even in the present day, Li-ion batteries remain a common power source for portable electronic devices like smartphones, laptops, and tablets. There is a wide range of sizes and forms available for Li-ion batteries. You can recharge it by using a solar battery charger. The solar battery charger is an environmentally friendly, cost-effective, and sustainable solution to charge batteries. The recharge time for these batteries is 50% less than that of NiMH batteries, making them superior. The downsides include high prices, overheating issues, and even fires.

Nickel Metal Hydride (NiMH) battery light

In terms of market share, NiMH batteries have surpassed NiCd batteries to become the preferred battery option for solar battery lights. These batteries were first developed in the 1960s but didn’t hit store shelves until the late 1980s. They’re inexpensive, have a high charge capacity, and are easy to dispose of without harming the environment. Even in terms of size, these batteries are practical because they are the same size as commonly used alkaline batteries.

Nickle Cadmium (NiCd) battery light

In the 1990s, these batteries rose to prominence as a top pick among rechargeable options. Because of their compact design, they quickly became the standard for consumer use. These batteries have a significant benefit over alkaline batteries in that their voltage does not fluctuate. Unlike rechargeable batteries, whose voltage remains constant until they are completely depleted, alkaline batteries’ voltage drops steadily as they are used up, sometimes to as little as 0.9 volts. NiCd batteries have a short lifespan of only a year or two, so it’s important to change them out every year in solar battery lights.

Why should you use solar battery lights?

Eco friendly

Solar battery lights use natural energy, and it is not generated by any fossil fuel or renewable energy source. So, they have a smaller environmental footprint than conventional lights. As a result, no greenhouse gases, such as carbon dioxide, are released when using these lights.

Solar lights are environmentally friendly since they turn the sun’s energy into usable form and store it in a battery overnight. The battery’s stored energy is released as soon as the sun goes down, lighting up the surroundings. Because of this, solar energy may be used indefinitely to protect our planet.

Available in smart designs

Solar battery lights are available in different parameters, such as LUX levels, beam angle, and weather conditions. The designs also consider days of autonomy, lamp post angle, battery and panel size, etc. These are set by clever engineering during design and installation. This is due to the fact that solar battery lights are made to provide optimal performance over extended periods of time. These factors are typically ignored when designing and setting up standard lighting.

Superb illumination

The vast majority of today’s solar-powered battery lights are equipped with or have space for brilliant LEDs. In contrast, you can color those LEDs to achieve the highest possible CRI. Their brilliant light boosts visibility throughout the day and makes them practically invisible after dark. However, the metal halide bulbs used in conventional lighting can’t hold a candle to the efficiency and brightness of our LEDs.

Tips for improving solar battery lights performance

You must avoid overcharging. If you want your solar panels to work at their best, you need clean them on a regular basis. The charging procedure can be impeded by the accumulation of dust and other contaminants. Moreover, sunlight is blocked by the layer formed by the dust.

The solar lights’ charging process can be disrupted if they are stored in the shade. Batteries need at least four hours of direct sunlight per day to charge properly.

The same goes for solar battery lights you want to use for an extended amount of time before being put away.


Most individuals don’t know how to properly care for solar battery lights, and others may even try to save money by using an old battery. We hope that this article has answered your questions about solar battery lights. You can now quickly and simply select the battery type that best meets your needs. Even though a solar battery light can be pricey, it is unquestionably a wise financial investment. Thus, you need not fret over the associated expenses, as they will be recovered in due time.
