It is an all-in-one solution for battery charger, trickle charger, maintainer and desulfurizer with 7-step charging procedure (desulfurization, initialization, bulk charge, absorption, recondition, float, pulse maintenance). 【Battery Repair and Pulse Maintainer】12 volt battery charger automotive features auto desulfurization, take newest pulse repair function to restore lost battery performance, help to restore older/idle batteries and extend battery life. When the battery is fully charged, the car battery trickle charger current will automatically drop and go into pulse maintenance mode to ensure that the battery is fully charged and will not be damaged by overcharging. 【LED Display Precision Charging】24V trickle charger adopting LED display, clearly show the voltage and current, enjoy accurate charging. The charger does not need to be plugged into the power supply, connecting the positive and negative battery terminals can detect and display the residual voltage of the battery. Adopts heat-resistant and oxidation-resistant copper charging cable for more durability, fully wrapped clips for safer use. 【Multiple Safety Protection】24v battery charger is capable of reverse polarity/over-charge/over-voltage/over-current/over-heat/short-circuit protection, charging will be stopped when an error occurs with a red light alert, and the system will protect the battery from damage. Operate in a temperature range of -4°F to 104°F. Winter Mode, +0.2v on the basis of the original charging voltage, better boosts your battery activity and charges more thoroughly in low-temperature situations. 【AfterSales Service】PZ.P is a professional manufacturer.
