Uses advanced circuit, intelligent protection, safer 2. Intelligent and efficient lithium-ion battery charger 3. Built-in cooling fan, effectively avoids charging and heating 4. Shell is made of high-quality flame retardant ABS material 5. High voltage time charging, intelligent IC controls the highest voltage charging time, effectively avoids damage to the battery Charger use and maintenance 1. This product is compatible with lithium-ion batteries. The positive and negative poles of the charging interface must match the charger's plug. 2. When charging, connect the battery first and then the AC power supply; after full charge, turn off the AC power supply and then unplug the battery. If you unplug the battery first when charging, especially when the charging current is large (the red light is on), it is easy to damage the charger. 3. The charging time must not exceed 24 hours, and the battery must not be drained and recharged. Otherwise, the battery cannot be protected or even damaged. 4. Use the charger in a dry place and unplug the charger when charging is complete.
