Chargers for batteries with different capacities cannot be mixed casually, otherwise it will cause greater damage to the battery.
•If the vehicle battery capacity is 14AH, use a 12AH charger. Do not use a 20AH charger, otherwise the battery will be easily damaged.
•If the vehicle battery is 20AH, use a 20AH charger. Using a 12AH charger will lengthen the charging time. Long-term use of a 12AH charger for charging will affect the battery life.
