Battery Capacity & Runtime — Match Your Solar Lights to Their Purpose
Upload Time:
Mar 01, 2025
The battery is the backbone of your solar light’s performance. Choosing the right capacity ensures your lights last through the night—whether illuminating a garden path or securing a remote farm.
Battery Capacity Basics
-
Measured in: Amp-hours (Ah).
-
Key Rule: Higher Ah = Longer runtime.
Choosing Capacity by Use Case
-
Home & Garden Lights:
-
Small Pathways: 2-4Ah (8-10 hours of light).
-
Security Lights with Motion Sensors: 5-8Ah (frequent bursts drain batteries faster).
-
-
Outdoor Adventures & Emergency Lights:
-
Portable Camping Lights: 5-10Ah (plus USB charging for phones).
-
Emergency Backup: 10-20Ah (multi-day runtime during outages).
-
-
Agricultural & Public Lighting:
-
Solar Street Lights: 20-30Ah (12+ hours daily).
-
Battery Types Compared
-
Lithium-Ion: Lightweight, 2000+ cycles, ideal for cold climates (-20°C performance).
-
Lead-Acid: Cheaper but heavier; suits stationary setups (e.g., barns).
Maximizing Battery Life
-
Avoid full discharges; keep charge above 20%.
-
Use batteries with deep-cycle technology for daily use.
-
Pair with solar controllers to prevent overcharging.
Power Your Priorities: From cozy backyard evenings to critical emergency scenarios, our solar lights feature long-lasting lithium batteries tailored to your needs.
