Frequently Asked Questions
Q: What does the A02F Lithium Battery Capacity Tester Module actually measure?
A: The A02F module measures the true remaining capacity of lithium batteries (such as 18650 cells), displaying the result on its built-in LCD digital screen. Unlike simple voltage meters, it gives you a genuine capacity reading so you can accurately assess the health and charge level of your batteries.
Q: Does the A02F tester save my settings automatically?
A: Yes! The A02F features an automatic save function — it saves your value settings automatically 5 seconds after you finish configuring them, so there's no need to press a save button manually.
Q: What is the minimum discharge stop voltage for the 18650 battery?
A: The A02F Lithium Battery Capacity Tester is designed with a minimum discharge stop voltage of 2.75V for 18650 lithium batteries. This helps protect your cells from being over-discharged, which can extend overall battery lifespan.
Q: What materials is this tester module made from?
A: The module is constructed from PCB (printed circuit board) and plastic, making it lightweight, durable, and suitable for both standalone use and integration into DIY electronics projects.
