Gel batteries perform best between 20°C–25°C (68°F–77°F). Extreme temperatures impact:
- Cold Weather: Reduced capacity (up to 40% loss at -20°C). Higher charging voltages may be needed.
- Hot Weather: Accelerated degradation (every 10°C above 25°C halves lifespan).
Mitigation Strategies:
- Insulate batteries in cold climates (but avoid overheating).
- Install in shaded, ventilated areas in hot environments.
- Use temperature-compensated charging to adjust voltage automatically.
Key Takeaway: Temperature management is critical—monitor and adapt charging accordingly.
