In response to growing industry demand for efficient, leagend has officially introduced its latest “Color Screen Battery Tester” series.

ROME, LAZIO, ITALY, June 29, 2025 /EINPresswire.com/ -- In response to growing industry demand for efficient, field-ready battery diagnostic tools with enhanced visual interfaces, leagend has officially introduced its latest “Color Screen Battery Tester” series. The new product line features four models equipped with full-color TFT displays, multi-function testing capabilities, and integrated data logging functions. Developed for automotive, industrial, and backup power system applications, the series is designed to improve diagnostic clarity and streamline on-site battery health assessments.

Series Overview
The new lineup includes the following four testers, each engineered for specific professional and field-service scenarios:

leagend BA4000: Color Screen 6V/12V/24V Vehicle Battery & 12V/24V Electrical System Tester with Printer
An all-in-one diagnostic instrument, leagend BA4000 evaluates battery CCA (cold cranking amps), internal resistance, voltage, state-of-charge (SoC) and state-of-health (SoH) across 6 V, 12 V, and 24 V systems. It also tests vehicle cranking and charging circuits. A built-in thermal printer delivers immediate hard copies of test results, while real-time voltage curves can be displayed for up to 120 seconds and saved in the tester’s 2,100-record memory

leagend BA640: Color Screen 6V & 12V & 24V Battery Tester
leagend BA640 provides comprehensive battery diagnostics—including CCA, internal resistance, voltage, SoC, and SoH—for 6 V, 12 V, and 24 V lead-acid batteries. In addition to battery testing, it evaluates vehicle starting and charging systems. This model stores up to 1,400 historical records and supports one-key batch testing with on-screen real-time voltage curve playback

leagend BA550: Color Screen 6V & 12V Battery Tester
Focused on 6 V and 12 V starter batteries and vehicle electrical systems, leagend BA550 measures CCA, internal resistance, voltage, SoC, and SoH. It incorporates a one-key quick-test mode for sequential battery checks and retains up to 1,400 test records. Built-in LED lights assist in low-light conditions, and graphic voltage curves can be recorded and reviewed on the 2.4-inch color display

leagend BA510: Color Screen 6V & 12V Battery Tester
leagend BA510 offers advanced diagnostics for 6 V and 12 V lead-acid batteries, combining battery performance testing with vehicle cranking and charging system analysis. It features a two-inch TFT color display for voltage curves, stores up to 1,400 historical records, and supports USB-connected printouts of test data. Built-in protection guards against short circuits and reverse polarity.

Key Technical Features
All four testers in the series share a suite of professional-grade capabilities:

- Full-Color TFT Display
Provides intuitive visualization of test results, including numerical values and voltage-curve graphics.

- Comprehensive Test Parameters
Measures CCA (20–2000 CCA), internal resistance, voltage (1–32 V DC), SoC, and SoH.

- On-Device Data Logging
Stores between 1,400 and 2,100 records (varies by model), allowing technicians to review historical data and identify performance trends.

- One-Key Quick Test
Enables batch testing of multiple batteries in succession without manual reset, improving workflow efficiency.

- Built-in Printer or USB Output
leagend BA4000 includes an integrated thermal printer; leagend BA510 supports USB-connected printing, facilitating immediate documentation of results.

- Ruggedized Protection
All models feature short-circuit and reverse-connection safeguards; leagend BA4000 adds automatic temperature compensation to maintain accuracy across –10 °C to 60 °C operating range.

Intended Applications
leagend Color Screen Battery Tester series addresses diagnostic needs across diverse environments:

Automotive Workshops
Rapid starter-battery health checks and alternator/charging system tests for passenger cars, commercial trucks, and motorcycles.

Field Service and Roadside Assistance
Portable, color-display diagnostics and quick-print capabilities support fast turnaround in mobile repair scenarios.

Fleet Maintenance
Batch testing of multiple batteries in logistics and transportation fleets, with onboard data logging to track battery life cycles.

Industrial and Off-Grid Systems
Verification of backup-power battery banks in data centers, solar installations, and UPS units—ensuring reliability in critical power applications.

Development Rationale
leagend reports that field technicians and workshop managers increasingly demand self-contained diagnostic instruments that minimize reliance on external devices and software. By integrating full-color displays, onboard data storage, and printing functionality, the leagend Color Screen Battery Tester series is positioned to reduce diagnostic setup time, improve data traceability, and support more informed maintenance decisions.
