• Self-Discharge: Very low (lower than standard flooded batteries); can be stored for long periods without recharging.

Environmental Recommendations

• Operating Temperature: Capacity reduces at low temperatures and service life is negatively impacted by high temperatures.
• Storage: The battery should be fully charged before storage. After 24 hours of no discharge, it is recommended to enter 'Storage Mode' at a lower voltage to reduce corrosion of the positive plates.
