Introduction
When sulfation has already occurred, proper repair methods can help restore OPzV batteries to near-original performance. Let’s examine practical repair techniques.
1. Slow Desulfation Charging
Using a low-current, high-voltage charge over several hours or days can gradually dissolve hardened sulfate crystals.
2. Pulse Desulfation Technology
Pulse chargers deliver high-frequency pulses to break down sulfate buildup without overheating the gel electrolyte.
3. Controlled Equalization Charging
Some professional systems apply a controlled equalizing charge under expert supervision to balance cells and dissolve sulfates safely.
4. Chemical Additives (With Caution)
Certain desulfation additives may assist the process but should only be used with professional guidance.
Conclusion
Proper desulfation can restore a sulfated OPzV battery’s performance, but prevention remains the best long-term solution. Always follow manufacturer recommendations to avoid electrolyte damage.
