10 Best Batteries For Solar Lights: Reviews & Buying Guide

Solar lights are the perfect and sustainable way to illuminate outdoor spaces. However, their efficient working even when the sun goes down is based on the quality of their batteries. Are you tired of solar lights that dim out too quickly or fail to last through the night? Then it’s mostly due to their inadequate battery performance. So, selecting and using the right batteries is necessary for the longevity, and efficient performance of the solar lighting setup.

Investing in high-quality batteries won’t frustrate you with frequent replacements or their failure to charge properly during cloudy days. Whether you’re lighting up a pathway, garden, or backyard, selecting the appropriate batteries is the only way to a successful solar lighting setup.

To make your purchase worthwhile, consider these three main factors that simplify your selection procedure and help you choose the ideal option.

• Battery Type – Nickel metal hydride (NiMH), lithium-ion (Li-Ion), and lead-acid batteries are three key battery types available. Both NiMH and Li-Ion batteries are lighter and offer high-energy density, fast charging, and long cycle life but they are a bit expensive. Lead-acid batteries are heavier and require regular maintenance due to old technology, even though available at an affordable range. So, most people prefer NiMH and Li-Ion batteries due to their newer technologies.
• Capacity – It determines the operating time of a fully-charged solar light, and it is measured in milliampere-hours (mAh). Most of these solar light batteries come with capacities, ranging from 200 to 2500 mAh (or more). Select the battery whose capacity should match the solar lighting requirements for its optimal performance. 
• Lifespan – Usually, batteries with a long lifespan don’t need any frequent replacements, and their lifespan depends on the charge and discharge cycle count. Lead-acid batteries offer a lifespan of 300 to 500 cycles, NiMH batteries have 500 -1000 cycles, and Li-Ion batteries offer a longer lifespan of 500 to 2000 charge-discharge cycles. So, choose the best option that suits your requirements.

Buying Guide For The Best Batteries For Solar Lights

The right batteries are required to truly maximize the potential of solar lights to illuminate your outdoor spaces. The selection requires careful consideration of various factors to make it suitable for your preferences and lighting requirements. So, we are here to guide you on how to choose the best and what factors to consider when making your purchase.

1. Types Of Batteries

Lithium-ion, nickel metal hydride, and lead acid are the three main battery types widely used for solar lights. Their selection will impact the light’s performance, lifespan, and environmental impact. However, lithium-ion (Li-ion) and nickel metal hydride (NiMH) are the safer, efficient, and the most preferred options in modern batteries. They use new technologies that make them last longer without harming the environment. Unlike old technology batteries, they don’t have a memory effect and thereby charge and discharge efficiently. Though these two types are expensive, the cost can be replaced with their benefits & longevity. While lead acid or nickel-cadmium (NiCd) batteries generally use old technology and affordable options. They offer less lifespan, heavier weight, and some memory effect that makes most users and manufacturers prefer batteries with new technology. 

2. Battery Capacity

Battery capacity is a crucial factor that tells us the amount of energy a battery stores and successfully turns into power to illuminate the solar light. Simply, it lets you know the operating duration of the solar light. It is expressed in milliampere-hours (mAh). Keep in mind that accurate capacity values might be affected by certain factors like light runtime, brightness, and local weather. Always choose the battery capacity based on your light requirements.

• For shorter operating lights (including step or pathway lights), select a solar battery with a low capacity of 200 – 500 mAh.
• For performing various outdoor lighting (like garden lights), you need a battery with a medium capacity of 600 – 1200 mAh.
• For lights that require expended performance (like security lights or floodlights), go with a battery with a high capacity of 1500 – 2500 mAh (or more).

3. Lifespan

As a user, it is essential to get an idea of the battery’s lifecycle. Usually, it differs from one type to another, and also their depth of discharge plays a key role in determining the lifespan of a battery. Mainly, the charge frequency, surrounding temperature, and battery composition will affect the lifespan (charge and discharge cycle). So, we suggest you choose batteries with a long cycle count to get rid of their replacing frustration quite often.

Lead acid batteries have the shortest lifespan of 300 to 500 cycles. NiMH or NiCd batteries can survive with a lifespan of 500 – 1200 cycles. Whereas, the Li-ion batteries offer the longest lifespan by supporting 500 – 2000 cycles (based on the cell quality). Among these three, Li-ion batteries are preferred most for their high cycle count, quick charging, and high energy den

4. Battery Size

Is battery size a crucial factor to check, does it impact the performance and longevity of the solar light? Simply to say, yes it is. The battery size impacts various characteristics like brightness, operating duration, and LED count of the solar lights. The battery size can be in either A, AA, or AAA.

• A-size batteries are quite big and hold a lot of energy to illuminate the light for an extended period. So, they are ideal to use for high-power solar lights (not the regular ones). However, they aren’t the preferred option for regular lights due to their bulky weight and large size.
• AA-size batteries are quite common, and the most preferred option, as they balance the size and capacity. Thus, these are found in numerous appliances, including these regular solar lights.
• AAA-size batteries are smaller and don’t hold as much power so they’re best for tiny solar lights or ones with low power consumption. These batteries are less powerful and require to be charged more often, which is why people tend to prefer AA-size batteries over AAA-size.

5. Energy Efficiency

Solar battery efficiency is measured by how well it turns stored energy into usable light. A highly energy-efficient battery in a solar light will boost how long the lights last and their overall performance, making sure not a bit of energy gets wasted. Concisely, if the solar lights are stuck with batteries that aren’t that great on the efficiency scale, you’ll notice they won’t last longer and illuminate brighter. Plus, there’s a lot of energy wastage.

Also, the type of battery a solar light uses matters a lot in its energy conversion efficiency. Take Li-Ion and NiMH batteries, which use newer technology to offer lower discharge rates and higher energy density than NiCd or lead-acid batteries. Thus, the new tech batteries will provide optimal performance with their higher energy efficiency than the ones with old technology.

6. Memory Effect

Older battery technology, think NiCd or lead-acid often shows the memory effect. This happens when you charge them again and again but don’t let them discharge fully first. The battery’s storage capacity goes down because of that. Then the battery starts “remembering” those halfway/partial charges and won’t fill up all the way. But those modern solar batteries, like Li-ion or NiMH, have newer tech that lets them drain a lot (deeper discharges) and charge back up well (efficient charging cycles). Thus, they avoid the whole memory issue so they keep performing consistently for a longer time.

7. Environmental Impact

Besides being the cost-effective and natural way of using solar lights, you need to think about the battery’s impact on the environment (Mother Earth). So, opt for rechargeable batteries rather than disposable ones to reduce wastage. Also, the type of rechargeable battery your solar lights use will matter a lot. Prefer Li-Ion, NiMH, or lithium-iron phosphate (LiFePO4) batteries, which are generally considered eco-friendly, recyclable, and less toxic to the environment. While NiCd contains harmful cadmium and needs careful disposal. So, choose batteries that have low eco-impact and offer proper recycling facilities.
