Installing solar lights in your outdoor space will significantly improve the aesthetics of your landscape, in addition to the security implications. As the battery is one of the most important components in any solar lighting system, it is critical that you get dependable ones either when installing the lights or when the old batteries run out.
Many solar batteries abound on the market today, such that making a good choice can be overwhelming. This is why we have selected and reviewed some of the best batteries for solar lights. We will also talk about some of the features and factors to consider when choosing batteries for your solar lights.
6 Best Solar Light Batteries & Our Reviews

Why You Should Trust Us on This Review?
When reviewing products, there are a couple of things to go by. Customer feedback and personal testing are the most important factors, and these two are our most important guidelines for reviewing products. Moreover, we have considerable experience in solar lighting (both indoor and outdoor), and we know what features and factors influence the quality of these solar lights.
Solar lights make use of different types of rechargeable batteries, so the first thing we did was to make a selection of different types of batteries from different brands. We largely relied on customer feedbacks in our assessment of these batteries as it testing the batteries out proved ambiguous.
Nonetheless, the AA batteries were tested with small battery-powered flashlights and fans to get an idea of how fast they drain. Taking into consideration our experience with some of these rechargeable batteries we have used with solar lights,
Kinds of Batteries for Solar Lights
There are different types of batteries that can be used with solar lights. What differentiates these batteries from one another is the chemical composition. So, when changing your batteries, endeavor to replace them with the same battery type.
Nickel Cadmium Battery
Nickel cadmium batteries are like the most portable solar batteries you can get. Portability is not the most important factor when it comes to solar light batteries. If you ever need portable batteries for your solar lights, you should consider this type of battery. When it comes to better capacity, nickel cadmium batteries are not the best. Also, they have some problems regarding charge memory.
Nickel-Metal Hydride Battery
There is not much difference between nickel cadmium batteries and nickel metal hydride batteries, apart from the fact that nickel-metal hydride batteries. It comes with hydrogen-absorbing alloy links. Furthermore, it is more environmentally-friendly and can hold more charge. The sheer environmental-friendliness and capacity of nickel-metal batteries make them one of the best for solar lights.
If you need the best batteries for your solar lights, then you should consider lithium-ion batteries. They can be quite expensive, but they take very little time to charge. They are also portable and environmentally-friendly. Lithium-ion batteries are also more durable than NiMH or NiCad batteries.
Lithium phosphate batteries are closely related to lithium ion batteries. However, lithium phosphate batteries are highly improved. Also, they are not so common, so it can be hard to get them if you ever decide to. An interesting thing about this type of rechargeable batteries is the uniform voltage output.
5 Factors To Consider When Choosing Batteries for Solar Lights
Replacing solar light batteries is a straightforward process once you have the replacement batteries. However, the work is in choosing the right battery for the solar lights. If you are looking for new batteries for your solar light, you should consider the following factors.
1. Battery Type
If you are replacing batteries that have run down, you first have to determine the battery you go searching for replacements. There are different types of rechargeable batteries, but you should always replace them with the same battery type. So, you should always go for the same type of batteries when replacing them.
The common types are the Nickel Cadmium Battery, Nickel-Metal Hydride Battery, and the Lithium-ion Battery. The battery type you have in your lights is what should determine the battery type you go for.
2. Battery Size
Another thing you have to check before replacing your batteries is the size. Outdoor solar lamps typically use two different battery sizes; the AA and the AAA. They can be easily mistaken for each other, as they have similar sizes. Nonetheless, be sure to have the right size when buying the batteries.
3. Battery Capacity
You should also establish what the sufficient battery capacity is for your solar lights. Battery capacity is rated in mAh. The higher the mAh, the longer the battery will last. High capacity batteries, however, take longer to charge.
4. Low Self Discharge
Over time, rechargeable batteries will lose charge if they are not used. They don't have to be connected to anything before this self-discharge occurs. Nonetheless, some manufacturers are able to minimize self-discharge by adding more insulation to the battery.
You should also establish how much you can afford to spend before you shop for batteries. Solar light rechargeable batteries are available at different prices. When compared to other types of batteries, they are typically more expensive. As they last long enough, the prices are always justified. You can always get affordable rechargeable batteries that will adequately power your solar lights. You don't have to go overboard and spend more than what you can afford.
New solar lights typically come with batteries, but if yours didn't come with rechargeable batteries, these batteries are some of the best options available on the market. Also, when your batteries run down and need replacement, these are all perfect options. Replace with the same type batteries that have the same size as the former ones. The rechargeable batteries are durable, and you can rest assured that you will get commensurate value for money spent. They are also not so expensive, and they offer good value for the prices at which they come.
