This charge device is designed to charge 12 V and 24V lithium, leadacid, LiFePO4 batteries from 6AH-120AH(12 V), 6AH-60AH(24V). 7-stage microprocessor controlled c-harging process provides the finest possible application and enables efficient battery c-harging, and the efficiency is ＞85%. Capable of recharging severely discharged or heavily sulfated battery. You can have a try. Features: This 7-stage microprocessor controlled c-harging process provides the finest possible application and enables efficient battery c-harging, and the efficiency is ＞85%. The outer is made of ABS material, insulation, flameretardant, high temperature. Freeze-resistant soft copper core line, with full coverage alligator clip, solid and practical. Stable output, high conversion rate, energy saving, large capacity, etc.. C-harging voltage adapts to temperature to prevents over or under battery c-harging. The c-harger can be used to check if the battery is seriously damaged. Equipped with LCD display, shows the c-harger inside temperature, c-harge voltage, c-harge current, desulphation mode, test mode, repairing mode, battery capacity and etc.. Equipped with winter mode(when the ambient temperature is below+10℃, raise the c-harge voltage) and summer mode(when the ambient temperature is above +28℃, reduce the c-harge voltage). Capable of recharging severely discharged or heavily sulfated battery. Reverse polarity protectionns, short circuit protections, over charge protections, parks free contact. Ease of use, clear c-harging status display. Full microprocessor controlled. Does not over c-harger your battery even if it is kept connected in any mode.
