One of the most significant issues OPZV batteries face in rainy conditions is terminal corrosion. Moisture, combined with oxygen, reacts with lead terminals, forming lead oxide or lead sulfate deposits. This increases resistance, reducing efficiency and potentially causing voltage drops.
Mitigation Strategies:
- Apply Anti-Corrosive Grease: A thin layer of petroleum jelly or specialized battery terminal protectors can prevent moisture contact.
- Regular Inspection and Cleaning: Check terminals monthly during wet seasons and clean any corrosion with a baking soda solution.
- Use Sealed Connectors: Waterproof terminal covers or heat-shrink tubing can minimize exposure.
Proactive maintenance ensures optimal conductivity and extends battery lifespan.
