1. Short circuit protection: Yes 2. Low voltage protection: Yes 3. Over current protection: Yes 4. Over voltage protection: Yes 5. Over temperature protection: Yes 6. Reverse connection protection: Yes 7. Microprocessor Control (CPU): Yes 8. Pulse Repair: Yes 9. Cooling fan(Low noise): Yes 10. LCD Display Screen: Temperature, current, voltage, power dispay(Display in turn) 11. Suitable for 12V motorcycles, cars, off-road vehicles 12. Types of batteries: Dry batteries, wet batteries, maintenance-free batteries, and most types of lead acid batteries including Calcium, GEL and AGM, Wet, EFB, etc. (lithium batteries are not allowed) 13. National standard pure copper wire: Can ensure stable current transmission, long-term charging of the wire is not hot, very safe. 14. Winter or Summer Mode: (Self-checking Outdoor Temperature, Automatic Opening Winter or Summer Mode) (1) Winter Mode: Cold weather and low temperature in winter cause large internal resistance and low voltage of batteries. If the normal voltage is insufficient, the charging voltage will be automatically increased in winter mode (2) Summer Mode: In summer, the temperature is hot, the battery voltage rises, and the normal voltage charging is easy to overcharge, which will do more harm to the battery. In summer mode, the charger will reduce the charging voltage, so that your battery will not overcharge. 14. High And Low Frequency Pulse Repair Technology: Using high and low frequency pulse repair technology, it has a good repair and activation effect for undervoltage batteries, batteries that have been idle for a long time, and batteries that can not be filled, so that your batteries will be refreshed.
