1. Four-slot independent programming professional test charger
2. Five functions: charge, discharge, discharge refresh, capacity test, internal resistance test
3. Different models, different brands, and different capacities for mixed charging
4. Mixed charging and discharging of any combination of 1-4 batteries
5. The large-size white backlit display is convenient for users to check the working mode, battery parameters, etc.
6. The scientific ventilation slot can quickly dissipate the heat inside the charger, ensure a good working environment for the circuit components, and prolong the service life
7. Adopting high-integration large-scale single-chip microcomputer, with strong I/O performance, fast running speed and strong instruction set
8. Temperature control design. The charger first relies on the metal sheet in close contact with the battery body to conduct the heat of the battery to the metal sheet, and then uses a temperature sensor-thermistor fixed with thermally conductive silica gel to convert the temperature into an electrical signal and send it to the microcontroller The port of the A/D converter is converted into a digital signal for the single-chip microcomputer to identify and perform corresponding processing according to the measured battery temperature value, temperature protection or normal charging, which guarantees the charging speed and the safety of battery charging
9. The channels do not interfere with each other. Each battery can be fully charged and automatically stop charging. Under the premise of ensuring full charge, the battery will not be overcharged to damage the battery, which can extend the service life of the battery.
10. Selection of the working mode of the charger: insert the battery and power on, the charger first self-checks, after the self-check is completed, press the MODE button for 5 seconds, the screen content starts to flash, and then press the MODE button successively. You can choose from five modes: CHARGE, DISCHARGE, DISCHARGE REFRESH, CHARGE TEST, and QUICK TEST. After selecting the working mode, wait for 10 seconds to automatically enter the newly selected working mode
11. Charging mode: This mode intelligently charges the battery according to the default charging current or the current selected by the user. The default charging current is 400MA and blinking. At this time, you can press CURRENT to adjust the charging current, and you can choose the charging current 500mA / 700mA / 1000mA / 200mA / 300mA / 400mA / (Only in the case of one or four slots, it can reach 1000MA) It will automatically stop after being fully charged. The capacity shows the capacity charged to the battery this time, not the true capacity of the battery.
12. Discharge mode: After this mode, the default discharge current is 300mA and flashes. At this time, you can press CURRENT to adjust the discharge current. The discharge current can be selected as 400mA / 500mA / 100mA / 200mA / Start to discharge according to the selected current, but the battery voltage reaches The discharge ends after 0.9v. This mode should be used periodically to ensure that the battery is kept in the best condition. Note that the battery is fully discharged after the discharge mode is completed. If necessary, you need to charge the battery immediately in the charging mode.
13. Refresh mode: This mode adjusts the battery internally according to the discharge-charge-discharge-charge-discharge-charge mode to reduce the internal polarization of the battery. This mode is used to repair the battery with degraded performance, or the battery performance is degraded due to improper use.
14. Capacity test mode: This mode is used to test the true capacity of the battery. It operates according to the process of charge-discharge-charge to perform a discharge test on a fully charged battery. The displayed capacity is the true capacity of the battery, which truly reflects that the battery can The power provided for electrical appliances can also be tested and judged whether the battery is good or bad.
15. Internal resistance test mode: This mode is used to quickly test the internal resistance of the battery. In this working mode, the internal resistance of the battery is quantitatively measured at an average working current of 500 mA inside the machine. Since the internal resistance of rechargeable batteries is generally very low, there may be some fluctuations sometimes due to the oxidation of the polar surface of the battery and the surface contact resistance. If there is uncertainty about the content of the test, it is recommended to measure several times in different battery slots, and then take the average value.
16. Button for adjusting current: After the self-check is completed, the charger first displays the battery voltage, and then displays the default current of 400mA and flashes. If you need to adjust the charging current, press the CURRENT button within 3 seconds to adjust in steps of 200mA Current, the display value is 500mA / 700mA / 1000mA / 100mA / 200mA / cycle display (if you only charge 1-2 batteries and put them in 1 and 4 slots, you can choose 1000MA charging current), after selecting the charging current, If there is no button operation within 10 seconds, the flashing current will stop flashing and enter the charging stage according to the set current, and the battery will automatically stop charging when the battery is full.
17. Display parameter switch key: during charging and discharging, press DISPLAY key to cycle display between current, voltage, capacity and time
