Features Constant Current Fast Charging: When the voltage of the charged battery is lower than the set value, 12V battery pack <12V, the charger quickly charges the battery with the maximum constant current. Generator Charger: Allow the starting motor to be started while the battery is being charged by the mains, automatically identifying the voltage level of the charged battery pack, and then automatically charging according to the battery voltage level. Stop Charging: When the voltage of the charged battery reaches the charging set value, 14V at 12V, the charging output is automatically turned off. Float Charging: When the voltage of the charged battery reaches the float charging set value, approximately 13.8V for a 12V battery pack, it automatically transitions to the float charging state, charging at a current of approximately 0.1‑0.2A, depending Current Limiting: When the charged battery is close to full charge, 12V battery pack ≥ 12V, the charging current is automatically limited. Feature: 1. Secure Protection: The product has comprehensive over current and short circuit protection. Due to its constant current feature, it will not be damaged in the event of a large battery capacity, extremely low internal resistance, load short circuit, or simultaneous starting of the starting motor during mains charging, when the starting current is very high, it is close to a short circuit for the charger. Meanwhile, due to this characteristic of the product, the charger does not need to be disconnected when the battery is used as a starting power source. Specification: Item Type: Generator Battery Charger Model: BC-12-5 Material: PCB, stainless steel. Input Voltage: AC 160-250V 0.9A Input Frequency: 50/60Hz Output Voltage: 12V Maximum Output Voltage: 13.8V 5A Working Temperature: -40℃ ~ +50℃ Relative Humidity: 98%RH, non condensing.  Package List: 1 x Generator Battery Charger Note: 1. The input voltage should not exceed 265V AC or 132V AC, otherwise it will damage the charger.2. The charger has a reverse protection function. If the positive and negative poles of the battery are reversed, the self recovery fuse inside the charger will be disconnected from the battery. After 10 minutes, the self recovery fuse will resume conduction, and the charger can continue working. Package List 1 x Generator Battery Charger
