ZB2L3 Battery Capacity Tester

ZB2L3 Battery Capacity Tester
    1.5V - 15V Battery Capacity Measurement and Discharge Device

    With the 1.5V - 15V Battery Capacity Meter you can  measure the capacity of lithium batteries and dry batteries. The capacity of batteries that are not used for a long time decreases. It is an ideal solution for finding out the usable capacity of such batteries. It comes with two resistors used in the discharge process.

Features:

•         1.5 v to 15 v Battery Capacity Meter Technical Specifications
•         Supply voltage: DC4.5-6V over Microusb Socket
•         Operating current: less than 70ma
•         Discharge voltage: 1V-15V resolution 0,01V
•         Termination voltage range: 0.5-11.0 V
•         Supported current: maximum 3A
•         Resolution 0.001A
•         Maximum voltage measurement error: 1% + 0.03 V
•         Maximum current measurement error: 2% +-0.010A
•         Product size: 50mm X 36mm X 17mm

    How to Use:

•   The battery you will measure must be fully charged.
•   Connect the battery to the battery input on the terminal, paying attention to the polarity. If the polarity is connected in reverse, the battery and the circuit may be damaged.
•   Make sure you use the resistor suitable for the battery. Do not operate it without a resistor.
•   Operate the module by supplying 5V from the Micro USB input.
•   The leds on the right of the screen show what the value on the screen is:
  •             Ah: decreasing current in mAh value
  •             A: Capacity
  •             V: Instantaneous voltage of the battery
•   When you press the arrow button, the discharge process starts.
•   By pressing the "+" and "-" buttons you can select at how many volts the discharge process will end.
•   In case of any problem the module will give an error. The meanings of the error codes are as follows:
  •             Err1: Battery voltage is higher than 15V.
  •             Err2: Battery voltage is lower than the termination voltage or the battery is not connected.
  •             Err3: The battery cannot withstand the load discharge, the current resistance is too large.
  •             Err4: Current is more than 3A.
  •             Err5: Due to improper use or connection error, the device is damaged and cannot be used again. ( The current sampling circuit or the mosfet is burned.) Improper use or wiring error has caused the device to burn out and cannot be used (current sampling or control switch MOS burned)
•   The resistor heats up seriously during the discharge process. Pay attention to this situation.
