Charging automatically stops when the\r\nbattery is full. Internal Resistance Measurement: Utilizes the DC two-wire\r\nmethod to provide reference internal resistance values. For the most accurate\r\nreading, measure when the battery is fully charged. Comprehensive Safety\r\nProtections: Features overheating protection and automatic power-off saving\r\nfor your settings. Flexible Discharge Voltage: Choose from 11 stop-discharge\r\nvoltage levels (2.5V to 3.5V). Dual Type-C Power Input: Includes two Type-C\r\ninterfaces for flexible power supply options (adapter and cable included).\r\nIdeal for Multiple Applications Whether you're sorting used 18650 cells for a\r\nDIY power bank, testing AA\/AAA batteries for household devices, or maintaining\r\nyour RC car battery collection, this tester provides the critical data you\r\nneed. Imagine quickly identifying weak cells in a batch, ensuring only the\r\nbest performers go into your projects. Important Usage Notes: After installing\r\na battery, wait a few seconds for the voltage and internal resistance readings\r\nto stabilize. Discharge current is fixed at a maximum of ~1A (non-adjustable,\r\nnon-constant current). Charging voltage is fixed at 4.2V. Not compatible with\r\nLiFePO4 batteries. Internal resistance readings may appear high at low\r\nvoltages; reinstall the battery for a more accurate measurement.
