Characteristics and Measurement Range of Small Battery Tester

Characteristics

1. Portability: The small battery tester is compact and lightweight, easy to carry and move, suitable for use in various environments such as laboratories, production lines, and maintenance sites.

2. Ease of Operation: It usually comes with an intuitive user interface and simple operation buttons, allowing users to easily perform battery performance tests without professional training.

3. High Accuracy: Advanced measurement techniques and algorithms are employed to ensure the accuracy and reliability of test results.

4. Multi-functionality: It can test key battery parameters such as internal resistance, voltage, and capacity, meeting basic battery performance evaluation needs. Some small battery testers also have battery status indication functions, such as "pass," "warning," and "fail," to help users quickly assess battery performance.

5. Safety: It has overcurrent and overvoltage protection functions to ensure that the battery is not damaged during testing and to safeguard user safety.

Measurement Range

1. Voltage Measurement Range: Typically covers from a few millivolts (mV) to several tens of volts (V). The specific range depends on the model and design of the tester, for example, some testers may have a voltage measurement range of 010V or 020V.

2. Current Measurement Range: From a few milliamperes (mA) to several amperes (A) or higher. Small battery testers may have a current measurement range such as 50mA~2000mA or similar to accommodate different battery testing needs.

3. Internal Resistance Measurement Range: From a few milliohms (mΩ) to several hundred miliohms (mΩ) or higher. Internal resistance is an important indicator of battery performance, and small battery testers can usually measure this parameter accurately.

4. Capacity Measurement Range: From a few milliampere-hours (mAh) to tens of thousands of milliampere-hours (mAh). The specific range depends on the model of the tester and the type and specifications of the battery being tested.

In summary, small battery tester is characterized by portability, ease of operation, high accuracy, multi-functionality, and safety. They have a wide measurement range, suitable for testing various types and specifications of batteries. When selecting a small battery tester, users should determine the required measurement range and functions based on the type, specifications, and actual needs of the battery being tested.
