ZB2L3 18650 Li-ion Lithium Battery Capacity Tester

Description

1. Battery Compatibility: The tester is designed for testing various lithium-ion battery types, including 18650 cells, which are a popular size for many applications.
2. Capacity Measurement: Its primary function is to measure and display the capacity of a battery in ampere-hours (Ah) or milliampere-hours (mAh). It helps determine the actual capacity of a battery compared to its rated capacity.
3. LCD Display: The tester typically features an LCD screen that displays essential information, including voltage, current, capacity, and test duration.
4. Discharge Load: The tester performs a discharge test on the battery under a specified load. It discharges the battery at a constant current rate, and during this process, it measures the voltage drop to calculate the battery’s capacity.
5. Adjustable Current: Some models allow you to adjust the discharge current rate, which can be useful for testing batteries at different rates or under specific conditions.
6. Automatic Shutoff: After completing the discharge test, the tester will automatically shut off, displaying the test results on the screen.
7. Voltage Monitoring: It continuously monitors the battery’s voltage during the discharge process to ensure it doesn’t go below a safe voltage threshold.
8. Safety Features: The tester may include safety features such as over-discharge protection and over-current protection to prevent damage to the battery being tested.
9. Applications: This tester is commonly used for assessing the capacity of lithium-ion batteries for various applications, including flashlights, power banks, laptop batteries, and more. It’s also helpful for identifying weak or deteriorating batteries.
10. Portability: The compact size of the tester makes it portable and suitable for on-the-go testing or use in the field.
11. Power Source: The tester is typically powered by a separate power source, such as a USB connection or an external power supply, to ensure accurate measurements.
12. User Manual: It’s essential to read the user manual provided with the tester to understand its operation and safety guidelines.
