Sulfation—a buildup of lead sulfate crystals—is a major cause of battery failure, especially in extreme temperatures. Learn how to prevent it.
How Weather Affects Sulfation
- Heat: Accelerates sulfation if batteries are left undercharged.
- Cold: Increases sulfation risk due to slower chemical reactions.
Prevention Tips
- Regular Equalization Charging: Helps dissolve sulfate crystals.
- Avoid Deep Discharges: Keep batteries above 50% charge.
- Temperature-Compensated Charging: Adjust charging voltage based on ambient temperature.
Sulfation is preventable with proper charging and maintenance, especially in harsh weather.
