With support for 1.2V to 15V discharge, the HW586 ZB2L3 Battery Capacity Tester Module measures cell health. It manages loads up to 3A and outputs live Ah, A, and V data. This Nuvoton-based version replaces the older STM8S003F3P6 microcontroller for updated logic processing.
Key Features
- Auto-Voltage Detection: Identifies battery termination levels across a 0.5-11.0V range. Prevents cell damage from deep discharge cycles.
- Broad Chemistry Support: Compatible with Li-ion, Ni-MH, and Lead-acid battery types. Measures capacity for 18650 cells and 12V packs.
- Live Metric Cycling: Toggles between Ah, A, and V on the display. Track real-time discharge behavior during the test.
- Micro USB Interface: Pulls 4.5-6V power from common mobile charging cables. Keeps testing active during routine load shedding.
- High Current Tolerance: Supports a maximum discharge current of 3.000A. Handles heavy loads for high-drain power tool batteries.
Frequently Asked Questions
How to calibrate HW586 battery tester?
New Nuvoton versions lack manual calibration modes found on older STM8 boards. Accuracy relies on factory-set internal voltage references.
What does Err3 mean on ZB2L3?
Err3 signals the battery cannot maintain the discharge current under load. This happens when internal resistance is high or the battery is empty.
