This is a intelligent fast charger with multi-functions: powerful charging with safe MCU control, touch button , test analyzer(battery capacity test), 0V activation to refresh the batteries, safe storage of batteries with volt.Limitation, 4 key control / 4-channel independent charging, muti-protection( anti reverse connection / short-circuit protection / overcharge protection, also it can automatically and timely monitor battery charging and discharging and detection process with one LCD screen of all battery information(charge volt. Capacity, charge percentage, selective current. What's more it has independent discharging function.
Test mode:It is to firstly fully charge the battery, then fully discharge the battery and record the discharged capacity and other parameters, then automatically fully charge the battery and record the charged capacity and other parameters. After charging is stopped, the discharged capacity, charged capacity and other parameters are retained on the screen and can be displayed in turn;
Discharge mode:Empty the battery, The system will automatically default the discharge current to 500mA, and the system will record the data during discharge, so as to test the battery discharge capacity.
Storage mode:This is a functional mode designed to store batteries more safely.When the battery is not used for a long time (such as more than 1 week), you can use this Storage mode, it will adjust the battery voltage to 3.8V (charge to 3.8V or discharge to 3.8V). Return the battery voltage to the factory voltage (3.65-3.8V). This results in longer battery life and safer storage.Only 3.7v battery has STORAGE function
