H1: Preventing Sulfation in Lead-Acid Batteries During Cold Storage
Sulfation is a major cause of capacity loss in lead-acid batteries. It occurs when batteries remain in a discharged or partially charged state for an extended period, especially in cold weather.
H2: Why Sulfation Worsens in Winter
Low temperatures slow down electrochemical reactions, making it harder for batteries to accept a full charge. This incomplete charging leads to lead sulfate crystals forming on the battery plates.
Over time, these crystals harden, reducing capacity and making the battery harder to recharge.
H2: How to Prevent Sulfation
- Always store batteries fully charged before winter.
- Recharge every 2–3 months during long storage periods.
- Use a battery maintainer to automatically keep voltage stable.
- Avoid storing batteries in cold, damp areas.
H3: Maintenance Best Practices
For flooded batteries, check the electrolyte level before storage and refill with distilled water if necessary. Do not overfill, as freezing can cause overflow.
Proper monitoring and temperature control can significantly slow down sulfation and extend service life.
