How long does it take to charge a 48V 12Ah battery?
1 Answers
It depends on the charging current. If the charger is 48V 2A, it will take about 6 to 7 hours. If it's 3A, it only takes 4 to 5 hours, and if it's 6A, it only takes about 2 hours to fully charge. Although a higher charging current speeds up the charging process, prolonged charging can damage the battery. Therefore, it is best to control the current at around 3A, with each charge not exceeding 4 hours. Precautions for charging electric vehicles: The battery should be charged promptly after use and should not be left idle for long periods, otherwise the battery plates are prone to sulfation. When the charging indicator turns green, it means the battery is usable or mostly charged, but it is still not 100% full. It is recommended to perform a long charge every week or every two weeks, i.e., continue charging after the green light comes on. After discharging, the battery begins the sulfation process, with noticeable sulfation occurring within 12 hours. Timely charging can remove less severe sulfation and help maintain the battery in optimal condition.
