Overview

The Battery Discharge Tester adopts constant-current discharge technology to evaluate the real capacity of storage batteries. It tracks key parameters including voltage, current, discharge time and accumulated capacity, applicable to battery activation, maintenance test and performance inspection. Featuring convenient operation and reliable discharge safety, this equipment serves routine battery testing work for rail transit, hydropower stations, communication base stations and UPS computer rooms.

Functional Features

Feature Name	Description
Comprehensive Safety Protections	Built-in overcurrent, short-circuit, overtemperature and reverse polarity protection to ensure full-process operation safety.
Multiple Alarm Functions	Real-time alarms and automatic discharge halt for overvoltage, undervoltage, out-of-range current, fan faults and other anomalies, protecting the tester and connected equipment.
Intelligent Operation Design	Equipped with quick-connect terminals for easy wiring. The entire test process supports automatic data recording and intelligent analysis, no manual intervention required.
Parallel Operation Support	Multiple units can be operated in parallel to meet discharge current requirements above 300A.
Rapid Capacity Evaluation	Estimate the residual capacity of the battery through a 3–5 minute quick discharge test.
Polymer PTC Load Resistance	Features low power consumption, excellent anti-surge performance, inherent overcurrent self-protection, and eliminates overheating red-hot risks for high safety.
High-Performance STMicroelectronics ARM CPU Main Control Board	Adopts dual-CPU redundant master-slave architecture for stable performance and rich functions. The master CPU handles instruction operation and calculation, while the slave CPU is responsible for alarm monitoring and process control. It ensures testing safety and reliability through dual-lock output and fault backup.
Presettable Discharge Parameters	Built-in universal discharge templates for various battery types. Templates are retained after power failure, enabling immediate testing upon startup without repeated parameter setting.
Professional Supporting Analysis Software	Simultaneously displays voltage & current curves, single-cell battery bar charts and data tables. Automatically generates test reports in Excel/Word formats, supporting data export and printing.

FAQ – Battery Discharge Tester

Q1: What is a Battery Discharge Tester?

A: It is professional test equipment to perform constant-current discharge testing on lead-acid, lithium and other batteries. It verifies actual capacity, detects bad cells and evaluates battery health under real load conditions.

Q2: What battery types can this tester work with?

A: Suitable for lead-acid batteries (VRLA, flooded), lithium iron phosphate batteries, nickel-cadmium batteries. Common voltage ranges: 12V, 24V, 48V, 110V, 220V battery packs.

Q3: What is the main purpose of discharge testing?

A: Measure real usable capacity; identify aging, underperforming single cells; check battery consistency; validate battery performance after maintenance; provide data for replacement decision.

Q4: What discharge modes are supported?

A: Constant current discharge (standard), constant power discharge, constant resistance discharge. Most models support automatic stop by capacity, voltage, time or temperature threshold.

Q5: How to set the discharge current?

A: Follow battery specifications. General rule: 0.1C recommended for standard capacity test; avoid discharge current exceeding maximum allowable discharge current to prevent overheating.

Q6: What safety protection functions does the tester have?

A: Over-temperature protection, over-current protection, battery reverse connection protection, over-discharge low voltage cutoff, fan failure alarm, abnormal stop and data auto-save.

Q7: Can I test a single battery cell or only whole battery bank?

A: Most models test whole battery strings. Optional cell voltage monitoring module can track each single cell voltage during discharge to find weak cells.

Q8: Will discharge testing damage the battery?

A: Standard-compliant discharge test will not damage healthy batteries. Do NOT discharge below battery manufacturer’s cut-off voltage; deep over-discharge will shorten service life.

Q9: Does the tester record test data?

A: Yes. It records voltage, current, temperature, cumulative capacity and test duration. Data can be exported via USB to PC for report generation and archiving.

Q10: What environment is required for testing?

A: Ventilated room, ambient temperature 0–40°C. Keep away from flammable gas from lead-acid batteries. Do not cover the cooling vents of the tester.
