The ZB2L3 18650 Lithium Battery Capacity Tester Module measures the real-world capacity, voltage, and discharge behavior of 18650 and similar rechargeable cells by draining them through onboard load resistors. A bright four-digit display tracks voltage, current, and accumulated capacity in mAh throughout the test.
Key features:
- Test Method: Active discharge testing through dual high-power load resistors for realistic capacity readings.
- Display: Four-digit digital display shows voltage, current, and capacity (mAh) in real time.
- Compatibility: Tests 18650, 26650, and other lithium cells as well as lead-acid and NiMH batteries.
- Controls: Three front-panel buttons set the discharge cutoff voltage and test mode.
- Power Input: USB Type-C powers the display and control circuit during testing.
- Connections: Gold-plated banana terminals and battery clip leads for a secure hookup.
This tester takes the guesswork out of sorting used or unlabeled 18650 cells, making it a handy bench tool for anyone building battery packs.
