The Mode mode has five functions: Charge, Discharge, Cap test, Storage, and Repair The default Charge mode of the system. Press on the MODE button to select other functions.
Charge
The system automatically determines the type of battery and recharges Li-ion
batteries or Ni-Mh, Ni-Cd batteries.
Li-ion batteries are charged in CC CV mode and Ni-Mh, and Ni-Cd batteries are
charged by -dV/dt mode.
Discharge
- This function can measure the capacity of batteries.
- The system automatically determines the type of battery, Li-ion batteries or Ni-Mh, Ni-Cd batteries.
- The Discharge mode is from constant current to cut-off voltage. Li-ion battery discharged to 2.5V, Ni-Mh, Ni-Cd battery discharged to 0.9V.
- The discharge capacity shown after discharge refers to the current capacity of the battery. It can discharge at any time with any battery above the cut-off voltage.
- For example, a lithium-ion battery with an initial voltage of 4.0V is discharged to the cut-off voltage with a constant current of 500 mA and a time-consuming of 4 hours.
- The discharge capacity is shown to be 500 mA*4 h=2000 mAh.
- Note that this is not the total capacity of the battery.if want to get the full capacity of the battery, please fully charge the battery and then discharge it.
Cap test
Cap test is short for capacity test, similar to Discharge mode, but more intelligent to test battery capacity.
There are three steps in this mode: Charge-Discharge-Charge
The charger fully charges the battery first. then discharge at a constant
current to the cut-off voltage, the charger shows the capacity of the battery.
Then the charger fully charges the battery again but the charging capacity is
not displayed.
Storage
In order to increase the cycle life of Li-ion batteries, the new version has added a storage mode. There is evidence that controlling the battery level to around 50% for storage will increase the battery’s lifespan. There is a discharge and charging process in the storage mode. When the initial voltage of the Li-ion battery exceeds 3.70V, It will discharge to 3.70V and stop. If the initial voltage of the battery is lower than 3.70V, it will be charged to 3.70V. The charge and discharge current reference charger parameters.
After the storage program is completed, the battery voltage will be around 3.7V.
Repair
Repairable li-ion batteries and Ni-Mh, Ni-Cd batteries When the over-discharge voltage of li-ion batteries is less than 2.5V, or the over-discharge voltage of lithium batteries with PCB is lower than the cut-off voltage.the charger is activated to charge with a small current, and the lithium battery can continue to be used.
There is a memory effect in some Ni-Mh and Ni-Cd batteries. The charger can refresh the battery and reduce the memory effect through repeated charging and discharging cycles.

Then multiple batteries have the same mode and current, which can save operation time. If you press display within 5 seconds after placing the first battery, you will exit the common adjustment mode, and the mode and current will flash to remind the user of the operation. If the first battery is not operated for more than 5 seconds, it will exit the common regulation mode by default and only charge this battery with a 500mA current.
At the top of the LCD screen, there are four cylinders, representing four slots, which can display the charging status of four batteries. There are five small black grid in the cylinder, representing a rough percentage of capacity. This is based on the battery voltage. They represent 20%, 40%, 60%, 80% and 100% of battery capacity respectively.If charged in the second slot ,If the battery is charged in the second slot,The small grid in the second cylinder of the display will continue to increase to the fifth grid, and then start again, reciprocating. This display indicates that the battery is charging. At this time, the display screen will display all the data of the second slot.voltage(V) ,capacity(mAh,Wh), temperature(℃), internal resistance（mΩ）, time （00:00）,current(mA) and percentage of capacity clearly（%）.If the battery is discharging, the cylindrical grid will flicker and decrease.
If multiple batteries are placed in the charger at the same time, we press the DISPLAY button several times to display the battery data of each slot in turn.each slot is independent of the other, there are slots to charge, there are slots to discharge, there are slots to repair the process, without interference with each other. . If CH1 is displayed, it will be the data of the first slot battery.

If you do not want a ringtone reminder, long press and hold the DISPLAY button to turn off the display screen during operation and there will be no ringtone reminder after the program is completed.
Technical points
In order to use this charger well, please read the following technical knowledge
Measure the internal resistance of batteries
The Auto mode of the charger distributes the appropriate current by measuring the internal resistance(DC IR).so it is necessary to measure more precise values. Please keep the positive and negative connectors of the charger clean and free of grease stain, and the positive and negative electrodes of the battery clean.And check the spring of each slot to ensure that the battery and charger are in good contact.
Measure battery capacity
Industry-approved test capacity method, room temperature of about 24 ℃, charge
battery with li-ion 4.20V, and then discharges at a constant current of 0.2C
to 2.5V. Please remember to keep a record of discharging time.
In this way, the capacity mAh of the battery is obtained by multiplying the
discharge current by the discharge time.
Capacity(mAh)= Current (mA)* Time (Hour)
So tell us that in order to use the S4 PLUS charger to measure the battery capacity more accurately, please measure room temperature around 24 degrees. If the temperature is too low, the battery capacity will be greatly reduced. Then choose the appropriate battery discharge current, about 0.2C rate. Please do not use the capacity shown during charging as the battery capacity, because many batteries are out of power from the device, and the battery voltage is about 3.0-3.4V.,the battery still have power.
In order to measure discharge capacity more accurately, we set the discharge cut-off voltage of the Li-ion battery at 2.5V. There are a lot of high capacity 18650,21700 batteries, The discharge mode is in the range of 3.0V-2.5V, and there are still about 50-200mAh capacity.
Current Selection
This charger has a high charge current 3A and a discharge current 1A, To ensure safety, please refer to the battery specification and select the appropriate charge and discharge currents in Manual mode. If the current is too high, the battery may become very hot and explode! In Auto mode, if the internal resistance of measurement is relatively large due to poor contact or oil stain, the allocated current will be relatively small. If you want to increase the charging current, press the current button for at least 2 seconds. The current of the display screen will flicker continuously, then pressing the current button can change the current. CC, CV mode is used for charging li-ion battery in the charger If li-oon battery voltage before charging is relatively high, such as 4.12V, put into the charger at Auto mode, even if the internal resistance is very low, very small charging current will be allocated,at present, it is in the CV stage of charging, that is, it will maintain a constant voltage of the battery, and the current will gradually decrease and cut of,so don’t misunderstand that the charger needs maintenance
Charger Temperature Control
Temperature sensors are installed in each slot of the charger to monitor the temperature of the battery in real time.If the battery temperature is too high, we will reduce the charging current intelligently,ensure safety.To increase temperature sensitivity, a milky white thermal conductive adhesive is added below the circular metal. If a small amount of colloid seeps out, please remove it with a cloth.
- Temperature is higher than 65 ℃. If the charging current is higher than 1500 mA(excluding 1500 mA), it will be reduced to 2 levels, for example, your current charge current is 3000mA, it will be automatically charged at 2000mA.
- The temperature of the slot is more than 70 ℃. If the charge current is more than 500 mA (excluding 500 mA), the charging current will be forced to drop to 500 mA.
Battery charging current level:
250mA, 500mA, 1000mA, 1500mA, 2000mA, 2500mA, 3000mA
Re-change MODE or CURRENT
If the battery is charging or discharging, other modes can be changed by pressing the MODE button for 2 seconds, and the current can be changed immediately after changing the mode, but the data on the previous display will disappear. Please be careful.
When the charger works normally, if it is in automatic mode, press and hold the current button for more than 2 seconds to forcibly change the current. When grease or other factors affect the measurement of battery internal resistance, we can forcibly select the appropriate charging current of the battery. In manual mode, press and hold the current button, and the current will not change.
Extending the Service Life of Charger
This is an intelligent multi-function charger.
In order to obtain a longer service life, please keep operating in dry
environment in the door, and have enough space to emit heat. In order to
prolong the service life, please try not to discharge/charge four slots at
full load for a long time. Because full-load operation will lead to the
increase of charger temperature, long-term high temperature of charger will
accelerate the aging of charger parts. Be kind to it and continue to serve
you.
