I work with automotive aftermarket retailers, distributors, and private label partners across North America to improve the reliability of battery-related product categories and strengthen end-customer trust.We help our partners address challenges across three key areas:1. Emergency starting systemsIn emergency jump starter products (including both lead-acid and lithium systems), common issues include performance degradation within the warranty period, reduced output in low-temperature environments, and a higher dependency on usage and maintenance conditions to meet real-world emergency requirements.2. Battery diagnostics and service consistencyIn battery-related operations, there are also frequent cases of inconsistent diagnostic results, misinterpretation, or differences in evaluation standards across tools, locations, and service networks.3. Fleet management and battery health visibilityIn fleet operations, operators often lack real-time and actionable visibility into battery health, state of charge, and aging trends.This can lead to unexpected downtime, higher operational costs, contract penalties, and loss of trust.Together, these issues directly impact customer experience, increase after-sales pressure, and may lead to higher return rates and reduced brand confidence.My work focuses on helping partners improve performance across starting systems, battery diagnostics, and fleet intelligence through more reliable product solutions and category development.Specifically, I help partners:• Build more reliable product portfolios in battery testing and starting solutions• Strengthen customer confidence in battery and starting system decisions• Reduce unnecessary battery returns and warranty claims caused by misdiagnosis• Improve diagnostic consistency across retail and workshop environments• Enhance fleet visibility and data-driven battery health managementI specialize in:• Supercapacitor-based automotive jump starter systems• Advanced battery diagnostic tools• Category development and private label programs for the North American automotive aftermarketAt Leagend, we work closely with partners to translate these technologies into practical, real-world solutions that improve operational decision-making and end-customer experience.If you are working on improving enhancing starting reliability, battery diagnostics, or developing next-generation starting systems, battery diagnostics, and fleet intelligence solutions, feel free to connect.
