While OPZV batteries are designed to be valve-regulated and spill-proof, extreme humidity or direct water exposure can still pose risks. Condensation inside battery compartments or faulty vent seals may lead to internal moisture accumulation, increasing self-discharge and potential failure.
Preventive Measures:
- Ensure Proper Ventilation: Avoid completely airtight storage to prevent condensation buildup.
- Check Vent Caps: Regularly inspect valve seals for cracks or wear.
- Elevate Battery Racks: Keep batteries above ground level in case of flooding.
A well-maintained OPZV battery should remain unaffected by rain, but vigilance is key in harsh climates.
