ZB2L3 BATTERY CAPACITY TESTER

ZB2L3 BATTERY CAPACITY TESTER

Description The ZB2L3 Battery Capacity Tester is a discharge-type tool that tests the external load capacity of batteries ranging from 1.2-12V, including 18650 batteries. It is a single-function device that controls the load cut-off to obtain real-time integrated discharge current capacity results. It supports a maximum discharge of 15V 3A through the discharge voltage and current but does not discharge by itself. The device can automatically identify and determine the appropriate battery termination voltage, which can also be manually adjusted, with maximum capacity statistics supporting up to 9999Ah (9999000mAh).

Specifications Power supply voltage: DC4.5-6V (micro USB connector) Operating Current: less than 70mA Discharge voltage: 1.00V-15.00V 0.01V resolution Termination voltage range: 0.5-11.0V Supported by current: 3.000A 0.001A resolution Maximum voltage measurement error: 1% + 0.02V Maximum current measurement error: 1.5% + - 0.008A Maximum battery capacity range: 9999Ah (1Ah = 1000mAh) greater value by shifting the decimal point to switch, when the display is less than 10Ah X.XXX, as shown above to achieve 10Ah XX.XX, and so on. Board size: 50mmX37mm

how to Calibrate ZB2L3?

Instructions 1. The first test should be fully charged battery.

2. Connect the battery to be tested positive to positive input, a negative input to the negative, can not be reversed (with load reversal may damage the circuit)! Load connected to the output of the positive and negative output, to work through the tester micro USB power supply (not available desktop or laptop USB powered), then the battery voltage.

3. Direct start test need only one press of the "OK" button, the tester can automatically develop an appropriate termination voltage of the battery full charge voltage, and will start flashing after the test three times. Need to develop artificial termination voltage only when the battery voltage display state by pressing "+" or "-" buttons to modify the termination voltage display beginning with P, behind the representative voltage resolution 0.1V, set up after pressing the "OK "start testing.

4. After the start of the test the tester will control the load of the electronic switch is turned on, the test data shows that the process will release capacity (Ah), current discharge current (A) and battery voltage (V) between the wheel was. When the battery voltage reaches the set cut-off voltage, load control switches off the tester display data stays in capacity (Ah) and above and the corresponding indicator flashes quickly together, now displays the actual capacity of the battery is discharging capacity, about the press "OK" to terminate flashing allows stable data display, press again "OK" button to return to the power-on state can just replace the battery test the next section.

Error codes and their meanings: Err1: battery voltage is above 15V Err2: battery voltage is lower than the termination voltage Err3: Battery can not afford to load or discharge current line too much resistance Err4: overcurrent (current exceeds 3.1A)

Q&A
Question 1: Why does the product not display when plugged into the charger separately?
Answer: The Type-C port on most chargers is set to have no voltage output by default. Consequently, the product will not be powered or display anything. Voltage output from the charger is initiated only upon detection of a load protocol, and it is at this point that the product will display the output.

Question 2: Why can't the test meter measure 10A or 120W on my product charger?
Answer: The values tested by this product are real-time charging parameters during the charging process. The parameters marked on the charger are the maximum power parameters of the product, and not always output such large parameters.

Question 3: Why occasionally displays a current of 0.01-0.02A when the output is not connected to a load?
Answer: This product uses bidirectional current detection, and a small no-load current is a normal phenomenon. However, it can also be reset by quickly touching the current reset interface three times.

Question 4: Why is the measured capacity value in this table significantly different from
the nominal battery capacity value of the mobile phone?
Answer: The measured capacity value in this table is the current voltage capacity value. If you need to know the capacity value of the phone's battery at 3.7V voltage, please use this table to display the power value and convert it according to the formula.
