Product Introduction
After years of research and development, our company has successfully developed a series of high-intelligence, high-precision battery discharge testers using our proprietary technology.
The discharge tester can operate in offline mode, using the battery as the discharge load. By continuously regulating the discharge current, it maintains a constant discharge current at the set value. During discharging, the instrument will automatically stop when any of the following conditions is met: the battery terminal voltage or individual cell voltage falls to the preset lower limit, the set discharge time is reached, or the set discharge capacity is achieved. Throughout the process, all valuable and continuous real-time data is recorded.
The battery discharge tester system uses wireless relay access to collect voltage monitoring information from individual cells in a simple, safe, and accurate manner.
The tester features a highly user-friendly interface, allowing users to complete various settings and data queries under menu prompts. Discharge process data can be saved in the device's internal memory and transferred to a USB drive via the data interface. The data can then be analyzed using dedicated PC software to generate required curves and reports.
The battery discharge tester is equipped with comprehensive protection functions, including audible and visual warnings, as well as clear on-screen interface prompts to ensure safe operation.

FAQs
Q: Why is battery charge-discharge testing necessary?
A: Through testing, it is possible to:
Determine whether the actual battery capacity meets the specified standards
Identify batteries with capacity degradation
Prevent backup power failures in advance
Extend battery service life
Improve the reliability of the power supply system
Q: Can the battery charge-discharge tester determine whether a battery needs to be replaced?
A: Yes. Through capacity testing, discharge curve analysis, and performance data evaluation, it can determine whether the battery has experienced capacity degradation, aging, or performance abnormalities, thereby assisting in the decision of whether replacement is necessary.
Q: Why is a battery charge-discharge tester needed in substations?
A: The DC system in substations relies on batteries to provide backup power. Through charge-discharge testing, it can be confirmed whether the battery bank has the reliable power supply capability required during power outages or emergency situations.
Q: Why do batteries require periodic discharge testing?
A: Under long-term floating charge conditions, batteries may experience issues such as capacity degradation and plate sulfation. Regular discharge testing can identify potential problems in advance.
