Sulfation is a major issue that reduces the effectiveness of GEL batteries. Causes include:
- Prolonged Undercharging: Incomplete charging allows lead sulfate crystals to harden.
- Long-Term Storage Without Maintenance: Batteries left unused without periodic charging accumulate sulfation.
- Low Voltage Discharges: Keeping the battery at a low charge level for extended periods.
Sulfation can be minimized by regularly fully charging the battery, avoiding deep discharges, and using desulfation charging techniques when necessary.
