As the battery continues to charge, the current drawn by the battery will gradually decrease. WFCO converters are designed to drop out of Bulk Mode when the total amperage draw from the converter reaches a preset point, indicating the battery is charged. If the amperage draw stays above the preset point, the converter will stay in Bulk Mode for a maximum of four hours. -
