Although OPzV batteries are “maintenance-free,” periodic checks are necessary for optimal performance.
Monthly Checks:
🔹 Voltage & Temperature: Ensure charging voltage is within specs.
🔹 Terminals: Check for corrosion and tighten connections.
🔹 Case Integrity: Look for cracks or swelling.
Quarterly Checks:
🔹 Capacity Test: Discharge test to verify performance.
🔹 Equalization Charge: If voltage imbalances are detected.
Annual Checks:
🔹 Internal Resistance Test: Identifies weak cells.
🔹 Thermal Imaging: Detects hot spots in battery banks.
Proactive maintenance prevents unexpected failures.
