HECC Certification was born from a deep conviction: Cambodian hybrid vehicle owners deserve impartial, precise, and honest technical assessment — a standard of excellence that simply did not exist in the region.
The OEM NiMH batteries in Toyota hybrids are particularly stressed by Cambodia's heat and humidity. Drawing on hands-on experience in electric conversion, HECC experts offer a proven alternative: replacement with modern lithium-ion modules, better suited to high temperatures, more energy-dense, and significantly more durable under local conditions — giving your vehicle a reliable second life.
Whether you are buying, selling, or simply checking the health of your battery, HECC provides data certified by tamper-proof software, independent of any commercial consideration. HECC also offers product solutions — lithium-ion replacement batteries, reconditioning — but these activities are strictly separated from the certification process. The passion for quality work is not a marketing argument: it is a daily requirement embedded in every diagnostic, every report, every recommendation.
