Solar street lights offer sustainable lighting for roads, parks, and communities by using renewable energy. Among all components, the battery is a critical part that directly impacts lighting duration, brightness, and lifespan. This article explores how batteries affect solar street light performance and what factors matter most.
1. Key Functions of Batteries in Solar Street Lights
- Store solar energy collected during the day
- Provide stable power supply to LED lights at night
- Enable smart lighting functions like timers or sensors
- Ensure lighting during cloudy or rainy days (2–5 days autonomy)
2. Common Battery Types for Solar Street Lights
| Battery Type | Advantages | Lifespan | Cost | Application |
|---|---|---|---|---|
| Lithium-ion | High energy density, compact, lightweight | 5–8 years | Moderate | Smart solar street lights |
| LiFePO4 | Thermal stability, safety, long life | 7–10 years | Higher | High-end/engineering projects |
| Lead-acid (Gel/AGM) | Low cost, mature technology | 2–4 years | Low | Budget-friendly systems |
3. How Batteries Affect Performance
- Lighting Duration: High-capacity batteries provide all-night lighting.
- Brightness Stability: Voltage consistency ensures no flickering.
- Energy Backup: Quality batteries offer 2–5 days backup for poor sunlight.
- Maintenance Costs: Long-life batteries reduce replacements and labor.
4. Factors When Choosing a Battery
- Match with LED power and lighting duration
- Adapt to local climate conditions (temperature range)
- Choose smart BMS-enabled battery packs
- LiFePO4 is preferred for reliability and safety
5. Battery Installation & Protection

✅ FAQ – Frequently Asked Questions
Q1: What is the best battery for solar street lights?
A: Lithium Iron Phosphate (LiFePO₄) is widely regarded as the best due to its long lifespan and safety.
Q2: How long do solar street light batteries last?
A: LiFePO₄: 7–10 years; Lithium-ion: 3–7 years; Lead-acid: 2–4 years.
Q3: Can I replace the battery in a solar street light?
A: Yes. Most systems are designed with replaceable batteries. Always match voltage and capacity.
Q4: What causes a solar light battery to fail?
A: Overcharging, deep discharge, water ingress, temperature extremes, and poor-quality cells.
Q5: What size battery is suitable for an 80W solar light?
A: A 12V 40Ah–60Ah LiFePO₄ battery is generally sufficient depending on backup needs.
Q6: Do all solar street lights include batteries?
A: Yes. All complete solar lighting systems include pre-installed batteries.
Q7: How do I maintain the battery?
A: Lithium requires minimal care. Lead-acid needs fluid checks and terminal cleaning.
Q8: Does battery health affect brightness?
A: Absolutely. A weak or degraded battery may cause dim lighting or early shut-off.

Solar Street Light Luyan
What types of batteries are used in Luyan solar street lights, and how do they work?
Luyan solar street lights use high-quality lithium-ion batteries. These batteries store the solar energy captured during the day and provide reliable illumination at night. Lithium-ion batteries are known for their longer lifespan, faster charging times, and better energy storage compared to traditional lead-acid batteries.
Battery Performance and Testing
What is a temperature cycling experiment?
1) The battery is changed from normal temperature to 66±3℃ and 15±5% for 1 hour.
2) Place it for 1 hour at a temperature of 33±3℃ and a humidity of 90±5℃.
3) Change the condition to -40±3℃ and leave it for 1 hour
4) Leave the battery at 25℃ for 0.5 hours
These 4 steps complete a cycle. After these 27 cycle experiments, the battery should have no leakage, alkali creep, rust or other abnormal conditions.
