Battery Capacity Tester Module ZB2L3 HW-586

The ZB2L3 HW-586 is your go-to solution for testing battery capacity with accuracy and ease. Whether you’re a DIY electronics enthusiast, RC hobbyist, or just someone who hates guesswork—this little device does all the hard thinking for you. This is useful for testing 1.5v to 15v batteries including AA, AAA, lithium, lead acid, 18650 batteries etc.

This battery capacity tester module is perfect for:

• Testing battery packs for drones, robots, or electronics projects.
• Evaluating used or recycled batteries before reuse
• Makers and DIYers who demand precision

Key Features:

• Real-Time Capacity Display: Measures discharge capacity (mAh) so you can see how much your battery truly holds.
• Intelligent Cutoff: Automatically stops when the battery hits the pre-set lower voltage level.
• Simple Interface: Just plug in and go—no complicated setup or programming required.
• Resistor Load: Uses external power resistors for discharge, giving you consistent readings.

How to use the Battery Capacity Tester:

First fully charge the battery then connect the battery to be tested positive to positive input, a negative input to the negative, can not be revers (with load reversal may damage the circuit)! Load connect to the output of the positive and negative output, to work through the tester micro USB power supply , then the battery voltage.

Direct start test need only one press of the “OK” button, the tester can automatically develop an appropriate termination voltage of the battery full charge voltage, and will start flashing after the test three times. Need to develop artificial termination voltage only when the battery voltage display state by pressing “+” 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.
