At AAPEX 2026, leagend will present professional battery testing solutions and the leagend JS400 SuperCap jump starter for automotive aftermarket businesses.
LAS VEGAS, CA, UNITED STATES, October 26, 2026 /EINPresswire.com/ — As a top manufacturer of automotive battery testing and related electronic products, leagend will present its professional battery testing solutions and SuperCap jump starter series at AAPEX 2026, taking place November 3–5 in Las Vegas, Nevada. The showcase will feature the leagend BA4000 battery tester, the leagend RT200 internal-resistance tester and the leagend JS400 SuperCap jump starter, each designed for a distinct application in the automotive aftermarket.
For distributors, importers, wholesalers and workshop-equipment suppliers, the lineup offers products to evaluate for different customer needs, from workshop testing and specialized battery measurement to permanently installed starting assistance.
Battery Testing for Workshops and Service Businesses
When a vehicle has a starting complaint, technicians need to assess battery condition and determine whether the cranking or charging system may also be involved. The leagend BA4000 tests 6V, 12V and 24V lead-acid starting batteries used in cars, trucks, motorcycles and boats, and evaluates vehicle cranking and charging systems on supported 12V and 24V applications. It measures cold cranking amps (CCA), internal resistance, voltage, state of charge (SoC) and state of health (SoH). Its real-time voltage-curve display helps technicians review voltage behavior during testing, while the built-in printer produces battery, cranking and charging test results on site. These functions support customer explanations and workshop service records. For distributors, the leagend BA4000 is a professional testing option for service businesses working across multiple vehicle types.
For applications requiring a more focused measurement of battery internal resistance, leagend will also feature the RT200, a dedicated instrument that measures internal resistance and voltage and automatically saves readings for later review. It is intended for professionals whose work specifically requires internal-resistance measurements.
Starting Assistance Designed to Stay with the Vehicle
The leagend JS400 takes a different approach from a conventional portable jump starter. It is designed for permanent installation on compatible 12V vehicles, where its supercapacitor bank remains installed and ready to provide starting assistance when needed. Unlike a portable unit with a built-in lithium battery, the leagend JS400 stores energy in supercapacitors and manages its readiness after installation, without requiring users to remove it for routine storage or periodically recharge an internal lithium battery.
During engine cranking, the leagend JS400 supplies additional current alongside the vehicle’s original battery, helping share the heavy starting load rather than replacing the battery. Its AI-based Self-Learning Mode observes the vehicle’s starting behavior to establish a baseline and help determine when assistance is needed. Through the Smart App, users can review battery voltage, charge level, temperature, starting activity and system status. Together, these functions make the leagend JS400 an onboard starting-support system for everyday use, rather than a device that needs to be retrieved and connected only after a starting problem occurs.
Stable, Reliable Operation in Low Temperatures
Cold weather can reduce vehicle-battery performance and make engine starting more demanding. The leagend JS400 is designed to operate from −40°C to 80°C. Its supercapacitor-based energy storage is designed to maintain stable, reliable performance in low-temperature conditions, providing starting assistance across a broad operating range without relying on a built-in lithium battery.
For distributors serving markets with severe winters, reliable operation in low temperatures is an important product consideration. The stated operating range describes the device’s designed operating conditions, not a guarantee of a successful start in every situation. Results still depend on vehicle compatibility, correct installation, the condition of the original battery and other operating factors.
A SuperCap Range for Different Vehicle Applications
The leagend JS400 is a key model in the leagend SuperCap jump starter series. The lineup also includes the leagend JS200 and leagend JS300 for compatible 12V passenger-vehicle applications, and the leagend JS600 for compatible 24V heavy-duty vehicles such as trucks and buses. This range gives distributors options to consider according to vehicle voltage, application requirements and local market needs.
A Broader Automotive Electronics Portfolio
Beyond battery testers and SuperCap jump starters, leagend’s portfolio includes battery monitors, battery chargers, OBD II diagnostic tools and thermal imaging products. These products serve distinct applications in battery monitoring, charging, vehicle diagnostics and inspection.
For importers, distributors, wholesalers and workshop-equipment suppliers, the range creates opportunities to discuss products across several automotive-electronics categories with one manufacturing partner. leagend welcomes inquiries about product sourcing, distribution, sample evaluation, private-label programs and OEM/ODM cooperation.
