HW586 battery capacity tester by 18650Tools is a single function discharge type tool designed to measure battery capacity and test discharge behavior using an external load. It provides real time integrated discharge current and capacity results, helping you evaluate cell performance quickly and reliably. Key benefits and features Real time discharge measurement: By controlling an external load, the HW586 delivers real time current and integrated capacity data for accurate evaluation of a battery's performance. Wide voltage range for common cells: Supports 1.2 to 12 V, suitable for testing cells such as 18650 Li ion and similar formats. External load discharge: Discharges are performed through an external load; the tester itself does not discharge the battery. capacity reporting: Capacity statistics can display up to 9999 Ah (9999000 mAh), enabling coverage of long test sessions and higher capacity cells. Automatic and manual termination control: Automatically identifies a suitable termination voltage for the discharge test, with the option to manually adjust the termination voltage as needed. Simple, purpose built operation: A single function unit focused on capacity testing with straightforward controls and clear results. Practical testing tool: Designed to support battery development, quality control, and service scenarios where understanding true capacity and discharge behavior is essential. Important specifications and capabilities Discharge method: External load controlled testing; the device does not provide the discharge itself. Voltage range: 1.2–12 V input range for testing. Discharge current and voltage: Supports discharge through an external load up to 15 V and 3 A as applicable to the test setup. Capacity display: Up to 9999 Ah (9999000 mAh) for comprehensive reporting. Termination voltage: Automatically identified for the test, with manual adjustment available. Use scenarios Scenario 1: Pre cell evaluation for a project Use the HW586 to test a batch of 18650 cells. Connect each cell, apply a controlled external load, and monitor real time discharge current and accumulated capacity to determine usable capacity and consistency across cells. Scenario 2: Quality control in a small manufacturing or assembly Incorporate the HW586 into incoming battery screening. Rely on automatic termination voltage detection to standardize cut off points, with the option to adjust termination voltages to align with your specification, ensuring uniform results across lots. Scenario 3: Service, , or end of life assessment Assess end of life cells or packs by measuring actual discharged capacity under a defined load. Compare results to nominal specifications to decide reuse, repacking, or disposal, without introducing self discharge from the tester. Notes The HW586 is designed to be a straightforward, reliable tool for capacity testing using external load discharge. It offers clear, real time results and flexible termination options while keeping the testing process focused and easy to manage.
