Product Overview & Application Scenarios

Product Overview
The HM3932 Battery Activator is a professional maintenance device that restores the capacity of aged lead-acid batteries through a controlled charge-discharge process. It is primarily used to extend battery lifespan and enhance power supply reliability. This tester functions as a discharge load for offline batteries, achieving constant-current discharge at preset values by continuously adjusting the discharge current.
Application Scenarios
1. Telecommunications Industry: Backup battery banks for communication base stations and data center equipment rooms.
2. Power Systems: DC operating power systems and UPS batteries for substations and power plants.
3. Uninterruptible Power Supply (UPS): Backup batteries for UPS systems in data centers, hospitals, and financial centers.
4. New Energy and Energy Storage: Energy storage batteries for solar and wind power generation systems.
5. Transportation: Backup batteries for signaling systems and emergency lighting in railways, subways, and airports.

Features & Advantages
Utilizes high-power wire-wound resistors for more stable and rapid discharge currents.
Features a USB port to transfer charging/discharging data to a USB drive for importing into a PC. PC data management software analyzes battery discharge processes and generates corresponding data reports, facilitating data transfer.
Incorporates intelligent ARM microcontroller control with a 7-inch touchscreen LCD displaying Chinese and English interfaces. Menu operations are simple and intuitive.
Automatic protection functions: automatically halts discharge and triggers an alarm when any of the following conditions occur: preset charge/discharge duration reached, preset charge/discharge capacity reached, battery voltage falls below the minimum protection threshold, or abnormal load connection detected. The system also automatically records the shutdown method.
Multiple charge/discharge termination conditions, including battery pack termination voltage, discharge capacity, and discharge time, ensure safe discharge testing.
Supports setting up to 10 automatic discharge-charge cycles.
