Sulfation is one of the most common issues in OPzS lead-acid batteries. It occurs when lead sulfate crystals form on the battery plates, reducing the battery’s ability to store and release energy efficiently.
Causes of Sulfation
- Undercharging: When the battery is not fully charged regularly, sulfate crystals accumulate on the plates, making it harder for the battery to recharge properly.
- Long Periods of Inactivity: If a battery is left unused for a long time, sulfation can build up.
- Low Electrolyte Levels: Insufficient electrolyte can cause sulfate buildup, reducing the plate’s active surface area.
How to Prevent Sulfation?
- Charge the Battery Fully: Regular full charging helps break down small sulfate crystals before they become problematic.
- Use the Battery Regularly: Avoid leaving the battery unused for long periods.
- Check Electrolyte Levels: Keeping electrolyte levels in the recommended range helps prevent sulfation.
