Corrosion is a leading cause of failure in OPzS batteries, affecting performance and safety.
1. Causes of Corrosion
- Overcharging: Generates excess hydrogen and oxygen, accelerating terminal corrosion.
- Acid leakage: Spilled electrolyte can corrode battery terminals and racks.
- Humidity and salt exposure: Increases oxidation rates, especially in coastal environments.
2. Preventive Measures
- Apply petroleum jelly or anti-corrosion spray to terminals.
- Use corrosion-resistant terminal connectors (e.g., tin-plated brass or lead-plated copper).
- Inspect terminals regularly for signs of oxidation or acid buildup.
- Neutralize acid spills with a baking soda solution to prevent further corrosion.
