Battery Capacity Tester For 18650 li-ion/lead-acid Batteries - 1.2v - 12v

Overview:

The ZB2L3 Battery Capacity Tester can to provide the integrated discharge current load capacity of 18650 batteries in real-time. Maximum testing support is 15v 3A. The unit can automatically identify the appropriate battery termination voltage which can also be manually adjusted.

Specification:

• 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

Instructions:

• The first test should be on a fully charged battery.
• Connect the battery’s positive terminal to the positive input and negative terminal to the negative input. Incorrectly connecting the terminals may damage the circuit. Connect the micro USB power supply (not supplied).
• Do a direct test by pressing the "OK" button. You can automatically setup an appropriate termination voltage of the battery’s full charge voltage, and the unit will start flashing after three times. Setup the termination voltage only when the battery voltage is displayed - press "+" 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.
• After the control 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). When the battery voltage reaches the set cut-off voltage, load control switches off. The display data stays in capacity (Ah) and above and the corresponding indicator flashes quickly together, and now displays the actual discharging capacity of the battery. Press "OK" to terminate flashing. Press the "OK" button to return to the power-on state.

Error codes and their meanings:

• Err1: battery voltage is above 15V
• Err2: battery voltage is lower than the termination voltage
• Err3: Battery cannot load or discharge current line - too much resistance
• Err4: overcurrent (current exceeds 3.1A)

Package includes:

• 1 x Battery Capacity Meter Tester
• 2 x load resistors
