Top Solar Batteries for Outdoor Lights: Keep Your Yard Bright All Night
Keeping your yard illuminated at night is both convenient and safety-enhancing. Solar batteries are often used to power outdoor lights because they can collect and store energy during the day when the sun is out, and then use that stored power at night to keep the lights bright until dawn breaks.
If you’re interested in investing in batteries for outdoor solar lights, you’ve come to the right place. Read on to learn the best battery types for this application, plus what to consider while shopping.
What Are the Best Batteries To Use for Outdoor Solar Lights?
You can keep your outdoor lights powered with a variety of solar battery cell compositions, including the following:
Li-ion: Lithium-ion batteries are among the most popular in today’s market because of their high energy density and longevity. They can last up to 1,000 charge cycles, which makes their higher price tag worth it. However, lithium-ion batteries aren’t regularly used for high-powered solar lights because they have specific charging needs, and their cost can add up.
NiCad: Nickel-cadmium battery cells are known for their temperature resistance, making them a strong option for outdoor solar lights. Unfortunately, this kind has environmental concerns because they contain cadmium, which is toxic, so disposing of them safely can be a challenge.
NiMH: Nickel-metal hydride cells are one of the most commonly recommended options for solar lights because they’re environmentally friendly, energy-efficient, and durable enough to withstand outdoor environments. They don’t contain toxic heavy metals and have a high capacity, allowing them to perform well in these conditions.
LiFePO4: Lithium iron phosphate batteries are a newer cell type that provides a long lifespan, improved safety, and exceptional stability, especially compared with traditional Li-ion batteries. The only downside to LiFeP04 batteries is that they’re typically the most expensive. These batteries are used in all EcoFlow Solar Generators, making them a great alternative with a much longer battery life than regular batteries.
Lead-Acid: Traditional lead-acid batteries are the cheapest and most cost-effective option, but are bulkier and require more maintenance.
Batteries for Solar Lights: How to Choose
Choosing the right batteries for your solar lights is a personal choice. Consider these factors to make the best decision for you and your home.
Battery Type
Choose the battery type that best suits your needs. If you prioritize cost, lead-acid batteries would be a good choice. If you care more about safety, longevity, and stability, we recommend using a LiFeP04 solar battery. All EcoFlow DELTA Series Generators use this battery type. Here’s what to know: all our batteries are safe, durable, quiet, and eco-friendly.
Capacity
When purchasing a battery for solar lights, you’ll need to consider the capacity to ensure it can power your lights long enough to last through the night. This depends on how many lights you have, how many watts each requires, and how long you need to run them at night.
One EcoFlow DELTA 3 Series Solar Generator (PV220W) provides 1024 Wh capacity, which could power around 8-16 solar lights, depending on their wattage and usage.
Number of Batteries
Think about how many solar batteries you want to power and for how long. A standard home with pathway and accent lights may only need a single battery, while larger properties with extensive lighting needs may require multiple batteries working together.
Compatibility
Ensure your batteries are compatible with your solar light system. They may require specific battery types or voltages to work. Check the manufacturer’s specifications to determine compatibility before purchasing a battery.
Price
The price of batteries for outdoor solar lights will vary widely based on the kind you choose, their capacity, and the brand. Lead-acid batteries are cheaper upfront, but they have a short lifespan, which can create higher long-term costs. LiFeP04 batteries, like the ones used in EcoFlow products, require a higher initial investment but provide a better value over time because they have a long lifespan and perform better.
Lifespan
Lifespan also comes into play. A short-lived battery may not even allow your lights to make it through outdoor movie night, while a battery with a long lifespan can keep your yard illuminated the entire time the sun is down.
Temperature Performance
The battery you choose will likely need to be set up outside, so you need a battery that can handle temperature changes. Cold weather can decrease battery capacity, while extreme heat can shorten lifespan. Batteries with advanced thermal management systems can help maintain better performance, whether hot or cold outside, making them suitable for year-round outdoor use.
Environmental Impact
If you’re an eco-conscious consumer, you should know that traditional lead-acid and NiCad batteries contain toxic materials and have shorter lifespans, making replacement more frequent and disposal more challenging. LiFep04 batteries are more environmentally friendly because they don’t contain harmful materials and have longer lifespans.
Frequently Asked Questions
Which Is Better for Solar Lights, Nicd or Nimh Batteries?
NiCd batteries handle deep discharges better and perform better even in low temperatures, so they are a better option for outdoor solar lights. NiMH batteries are eco-friendly and have a higher capacity, but they can easily overcharge and may not do well in high temperatures.
Which Type of Solar Battery Is the Best?
The best type of solar battery is LiFePO4. These newest models have an improved safety and stability profile, handle extreme temperatures well, and provide a long lifespan. The only downside is that they’re expensive, but the benefits make the cost worth it.
Do I Need Special Rechargeable Batteries for Solar Lights?
Solar lights need rechargeable batteries specifically designed for them. They usually use NiCd or NiMH batteries, but solar generators or portable power stations are better alternatives that last longer and are more versatile.
Is It Worth Replacing Rechargeable Batteries in Solar Lights?
Yes, it’s worth it to occasionally replace the rechargeable batteries in your solar lights because it will improve your lights’ performance, lifespan, and efficiency. They will provide brighter light and last longer. Replacing the battery is more cost-effective than replacing the entire light.
Final Thoughts
With a bit of forethought and planning, you can ensure your outdoor lights are paired with the best battery to ensure they shine bright the entire night, keeping your home and yard illuminated. If you’re interested in a robust option with versatility beyond just outdoor lights, consider investing in the EcoFlow DELTA Pro 3 Solar Generator (PV400W), which can power a significant number of lights and can also be used for appliances and more.
