ZB2L3 battery capacity tester, designed to measure the discharge capacity of batteries. It can test various battery types, including 18650 lithium-ion batteries, with a voltage range of 1.2-12V.
Here's how it generally works:
The tester discharges the battery through an external load.
It measures the discharge current, voltage, and capacity (in Ah) of the battery.
The test continues until the battery voltage reaches a set cut-off point.
The tester displays the actual capacity of the battery.
Additional information:
The tester can support a maximum capacity of 9999Ah (9999000mAh).
It can automatically identify and adjust the battery termination voltage.
Some models include a micro USB port for power.
