The capacity of the battery (Ah) and its depth of discharge (DOD) greatly affect its charging time. The estimated time to charge a battery is shown below. The table is for reference purposes only. The actual data may differ due to battery conditions.
Please select the appropriate model of Sigma battery chargers based on your battery capacity. The charging time for a battery whose battery capacity is outside the applicable range can be very long.
