Rainy weather often brings cooler temperatures, which can negatively impact OPZV battery performance. Lead-acid batteries rely on electrochemical reactions that slow down in cold conditions, reducing capacity and discharge efficiency.
Key Observations:
- A 10°C drop can decrease capacity by up to 20%.
- Charging efficiency drops, requiring longer absorption times.
- Sulfation risk increases if batteries remain undercharged.
Solutions:
- Temperature-Compensated Charging: Adjust charging voltage based on ambient temperature to ensure full recharge.
- Insulated Enclosures: Keep batteries in weatherproof but ventilated boxes to stabilize temperature.
- Avoid Deep Discharges: Maintain a higher state of charge (SoC) to counteract reduced efficiency.
