Solar street lights have become a preferred solution for cities, industrial parks, communities, and remote areas seeking reliable, clean, and cost-effective outdoor lighting. At the heart of every solar street light system is its battery. As a trusted supplier, JGNE provides high-performance lithium batteries for solar street lights, designed for long life, high efficiency, and stable outdoor operation.
Choosing the right battery directly impacts lighting performance, maintenance costs, and long-term system reliability.
This guide explains why lithium batteries outperform traditional lead-acid batteries and what factors you should consider before selecting a solar light lithium battery for your lighting projects.
Lithium Batteries vs. Lead-Acid Batteries
Although lead-acid batteries were widely used in early solar lighting systems, lithium technology has quickly become the new standard. The differences between the two are significant and directly influence performance.
1. Lifespan
Lead-acid: 300–500 cycles
Lithium: 2,000–4,000+ cycles
A lithium battery lasts 4–8 times longer, reducing replacement frequency and long-term cost.
2. Depth of Discharge (DoD)
Lead-acid: 50% recommended
Lithium: Up to 90–100% usable capacity
This means lithium batteries deliver much longer nighttime illumination hours without risk of damage.
3. Weight and Size
Lithium batteries are 70% lighter, making installation easier and reducing overall system load. For pole-mounted solar street lights, lighter weight equals improved safety and simpler integration.
4. Charging Efficiency
Lithium batteries charge 30–50% faster, allowing them to store more energy during short daylight periods or cloudy weather.
5. Maintenance Requirements
Lead-acid batteries require periodic maintenance, ventilation, and inspection.
Lithium batteries are completely maintenance-free, which is critical for outdoor lighting systems installed high on poles.
These advantages are why most modern solar lighting manufacturers and project contractors now prefer lithium batteries for solar street lights.
Why Choose Lithium Batteries Over Lead-Acid?
Lithium batteries deliver stronger performance where solar street lights need it most:
✔ Higher energy density for longer brightness
✔ Better low-temperature performance for winter environments
✔ Longer operational life, lowering total ownership cost
✔ Stable power output, ensuring consistent illumination
✔ Compact design, suitable for integrated and all-in-one solar lights
As part of its product line, JGNE offers durable and safe solar light lithium battery solutions engineered for outdoor endurance, backed by advanced BMS protection against overcharge, short circuits, and extreme temperatures.
Additional Key Factors When Choosing a Lithium Battery
1. Battery Capacity (Ah)
Capacity determines how long the street light can operate at night.
Common capacities range from 10Ah–60Ah, depending on lighting power and installation height.
2. Voltage Configuration
Most solar street lights use 3.2V, 6.4V, 11.1V, or 12.8V lithium packs.
Choosing the wrong voltage can lead to system failure—so compatibility is crucial.
3. Battery Chemistry
Different lithium chemistries offer different benefits:
LiFePO₄: Extremely safe, long life, ideal for high-temperature regions
Li-ion (NMC): Higher energy density, lighter weight
4. Outdoor Durability
A good solar lighting battery must be:
- Waterproof
- Dust-resistant
- Shockproof
- Capable of withstanding heat, cold, and humidity
JGNE designs battery packs specifically for harsh outdoor climates, making them a reliable wholesale solar light lithium battery supplier for global lighting projects.
5. Certification and Quality
- Look for suppliers with:
- ISO certifications
- UN38.3 / MSDS
- Long-term cycle testing
Reliable manufacturers like JGNE ensure consistent quality for both small projects and bulk orders.
