HDGC3980 Battery Discharging Tester (Accurate capacity test)

HDGC3980 series battery discharge tester is used for various battery pack discharge experiment, capacity test and daily maintenance. It can monitor the voltage, discharge current, discharge time, discharge capacity, and other parameters in the discharge process in real time, which has the advantages of easy operation and safe discharge, and is widely used in the fields of telecommunication base station, transformer station, rail transportation, hydroelectric power station and UPS data centre.

Description

Battery discharging testers are essential diagnostic tools used to evaluate the performance, capacity, and reliability of battery systems. These instruments simulate real load conditions to measure remaining battery capacity, verify discharge performance, and identify weak cells before system failure.

HD Power battery discharging testers are designed for industrial battery maintenance, including telecom backup batteries, UPS battery banks, substation DC systems, and energy storage batteries. With intelligent monitoring, constant current/power discharge control, and wireless cell voltage monitoring, these testers provide accurate battery health diagnostics and reliable maintenance solutions.

The HDGC3980 and HDGC3982 series can monitor battery voltage, discharge current, capacity, and discharge time in real time during testing.

FAQs

What is a battery discharging tester used for?

A battery discharging tester is used to simulate real load conditions and evaluate battery capacity, performance, and reliability. It helps detect weak batteries and ensures backup power systems function properly.

Why is battery discharge testing important?

Discharge testing verifies the actual capacity of a battery. Over time, batteries degrade and may no longer deliver their rated capacity, which can cause unexpected power failures.

What is constant current discharge testing?

Constant current discharge testing keeps the discharge current stable throughout the test to accurately measure battery capacity and performance.

Can this tester monitor individual battery cells?

Yes. The HDGC3982 model supports wireless battery cell monitoring modules that measure the voltage of each battery cell in real time.

How many battery cells can be monitored?

Each wireless monitoring module can monitor up to 12 cells, and multiple modules can be connected to monitor up to 300 battery cells in a battery bank.

Can multiple testers work together?

Yes. Multiple testers can operate in parallel to achieve higher discharge currents when testing large battery banks.
