In January 2026, TZST’s annual extreme cold weather testing continued in China’s Heihe region. Amid sustained temperatures below -30°C, TZST’s truck-starting lithium battery series successfully completed multi-day, multi-scenario start-up validations. Achieving zero failures throughout the testing process, the results once again confirm the outstanding reliability and robust environmental adaptability of TZST batteries under extreme cold conditions.
The testing simulated real-world harsh operating conditions that users in severe winter regions may encounter. The testing team placed TZST truck-starting lithium batteries (covering popular market specifications such as 150Ah, 230Ah, and 280Ah) directly in an outdoor environment below -30°C, with no insulation, allowing them to freeze completely. After this extreme low-temperature exposure, the batteries faced their first challenge: starting an on-site heavy-duty truck. Test results showed that all batteries achieved successful starts on the first attempt, demonstrating excellent instantaneous discharge performance and system stability in low temperatures.
To further validate the batteries’ performance retention after prolonged cold exposure, the testing team arranged a more demanding task after the batteries had been left outdoors for over 24 hours: starting a large bulldozer that had been parked in the open for more than a month. Facing compounded challenges such as increased oil circuit resistance and mechanical friction due to long-term idling, all three TZST battery models (150Ah, 230Ah, and 280Ah) successfully started the equipment again. This not only proves the batteries’ operational capability in extreme cold but also demonstrates their ample power and reliability in activating heavy machinery that has been out of service for extended periods.
The most critical validation took place on the third day of outdoor exposure. After enduring continuous extreme cold for over 72 hours, the same batch of TZST batteries was tasked with starting the heavy-duty truck once more. The results were compelling: all batteries successfully completed the start-up, with consistent and stable performance. This confirms that even after multiple days of exposure to temperatures below -30°C, TZST batteries effectively maintain their core starting performance and power output capabilities, fully addressing users’ concerns about equipment start-up reliability during harsh winter seasons.
The successful completion of this extreme cold test in Heihe serves as strong evidence of TZST’s deep expertise in lithium battery technology and its continuous efforts to enhance product adaptability to diverse environments. Through comprehensive technological innovation across the entire value chain, TZST ensures that its products can reliably meet the challenges of extreme climates, providing global users with all-weather, high-reliability power solutions. This proven technical capability, backed by rigorous testing, forms the solid foundation for TZST to earn customer trust worldwide.
