- ZB2L3 is a simple, cheap, standalone battery capacity tester. It connects to the battery and a load resistor. This module can discharge the battery by drawing current to the high wattage resistor. By calculating the discharging current, time and others parameter it can measure the capacity of a battery. The discharging limit can be set by user. This module has a 4 digit 7 segment display which shows different parameter like volts, current and capacity of the battery. The module is powered by 5v and has a micro usb port to connect the power cable.

it still shows me err3, why?
Why is it not tested on a fully charged battery?
I have just shown the way of testing the battery.
Man, those batteries with 6000mAh written on the side are so funny. Usually around 1000mAh or lower.
you're right
@@NTTronix i'm buying laptop batteries on sale, just to get the cells out, BUT i need a more precise measurement tool. I'm currently using a USB meter, which measures voltage, amperage and capacity, BUT only on 5 Volts.
I ordered this module, hopefully it'll be better to test with, connected directly to the battery.
So, most of batteries are fake then 🤣🤣🤣
