and high quality Made of high quality material, and practical to use This charger is suitable for all of 12V and 24V lead-acid batteries, especially for fully sealed solid state wide temperature battery charging. The working voltage is AC 160-250V, and the working frequency is 20~600Hz, which ensures that the engine can still charge at low speed. It can be replaced directly by the power supply of the generator to replace the charger. Colour: Black Material: metal + plastic It allows the motor to start when charging the battery through the grid. It can be by constant current and voltage. When the battery is nearly full, it will be converted to turbulent current and then automatically stopped. Since the system uses a soft-start design, it does not generate of electrical pulses. In addition, when the charger is connected online, the power system is not interrupted.
