leagend Battery Testers and SuperCap Jump Starters Broaden Aftermarket Opportunities at AAPEX 2026
From professional battery diagnostics to intelligent onboard starting assistance, leagend invites aftermarket partners to explore new ways to expand their product offerings, meet market demand and better serve customers.
LAS VEGAS, NEVADA — At AAPEX 2026, leagend will showcase two product lines that address distinct needs in the automotive aftermarket. Its professional battery testers help workshops assess battery condition and investigate starting-related concerns, while its SuperCap jump starters are designed to provide starting assistance from a permanent onboard installation. The leagend BA4000 battery tester, leagend RT200 internal-resistance tester and leagend JS400 SuperCap jump starter will lead the display at Booth V7315, Level 2 of The Venetian Expo in Las Vegas, November 3–5, 2026.
For distributors, importers, wholesalers and workshop-equipment suppliers, the showcase offers a chance to consider how these solutions could complement their existing ranges and serve different customers. As a top manufacturer of automotive battery testing and related electronic products, leagend will also welcome discussions about market requirements, product sourcing, distribution, private-label programs and OEM/ODM cooperation.
Battery Testers for More Informed Workshop Service
When a vehicle is difficult to start, technicians need to understand the condition of the battery and whether the cranking or charging system may also be involved. The leagend BA4000 brings these assessments into one professional testing instrument, supporting the decisions workshops make and the explanations they give customers.
The leagend BA4000 tests 6V, 12V and 24V lead-acid starting batteries used in cars, trucks, motorcycles and boats. It also evaluates cranking and charging systems on supported 12V and 24V applications. In addition to cold cranking amps (CCA), internal resistance and voltage, it measures 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. By bringing measurement, voltage review and printed reporting together, the leagend BA4000 helps workshops explain findings clearly and maintain useful service records.
Not every application, however, calls for the same testing approach. For professionals focused on battery internal resistance, the leagend RT200 provides dedicated internal-resistance and voltage measurement, with automatic saving of readings for later review. Alongside the leagend BA4000, it gives aftermarket equipment buyers a choice between broad workshop testing and more specialized measurement needs.
SuperCap Jump Starters Bring Starting Assistance Onboard
While battery testers help workshops understand starting-related conditions, vehicles may also benefit from additional current during demanding engine starts. The leagend JS400 addresses that need through a permanently installed design for compatible 12V vehicles. Its supercapacitor bank stays onboard and supplies current alongside the original vehicle battery during cranking, helping share the starting load.
The leagend JS400 stores energy in supercapacitors rather than a built-in lithium battery and manages its readiness after installation. Users therefore do not need to retrieve a portable booster when starting assistance is required or periodically recharge an internal lithium battery. Its AI-based Self-Learning Mode observes the vehicle’s starting behavior, establishes a baseline and helps determine when assistance is needed. Through the Smart App, users can review battery voltage, charge level, temperature, starting activity and system status.
Together, its installed format and intelligent functions make the leagend JS400 a differentiated option for distributors and automotive brands seeking to complement conventional portable jump starters with onboard starting assistance.
SuperCap Options for Different Vehicles and Markets
Regional conditions are another important consideration when selecting starting-support products. For markets with demanding winters, the leagend JS400 is designed to operate from −40°C to 80°C, with supercapacitor-based energy storage intended to maintain stable, reliable performance in low-temperature conditions.
Vehicle requirements also vary. The wider leagend SuperCap jump starter series includes the leagend JS200 and leagend JS300 for compatible 12V passenger-vehicle applications, as well as the leagend JS600 for compatible 24V heavy-duty vehicles such as trucks and buses. Together, these models give business partners options to evaluate according to vehicle voltage, operating conditions and local customer needs.
Explore New Possibilities with leagend at AAPEX
For buyers considering a broader product offering, leagend’s portfolio also covers battery monitoring, charging, diagnostics and inspection. Its battery monitors, battery chargers, OBD II diagnostic tools and thermal imaging products give aftermarket partners complementary categories to explore with one manufacturing partner.
At AAPEX, those discussions can begin with the needs of each market. Workshop-equipment suppliers may be looking to broaden their testing ranges, while distributors and importers may be considering onboard starting support or additional automotive-electronics products. leagend welcomes the chance to review suitable models and explore sample evaluation, sourcing, distribution, private-label development and OEM/ODM cooperation. These conversations can help identify ways to broaden product offerings and serve customers better.
Visitors can meet the team at Booth V7315, Level 2 of The Venetian Expo, November 3–5, 2026. To arrange a meeting or begin a conversation from outside the show, contact marketing@leagend.com.
