Chery Tiggo 8 CSH car battery underwent seawater immersion testing at PIK 2 Beach in Jakarta, with the battery actually immersed for 53 hours and 51 minutes, exceeding the planned 48 hours. After immersion, the battery was reinstalled in the vehicle and operated normally; technician inspections showed no significant impact. The test aims to verify the durability and safety of the battery system. Previously, this battery had completed extreme challenges in China including spiral rollover, two-vehicle collision, and seven-vehicle stacking pressure test (over 48 hours). The corrosiveness and conductivity of seawater far exceed ordinary rainwater, easily accelerating metal corrosion and insulation degradation. Traditional batteries may face risks of short circuits, fires, etc. in extremely humid environments. Chery's battery passed the test, proving its stability and safety under extreme conditions, highlighting its technological advantages. Indonesia is the first country where Chery conducted large-scale international battery extreme testing. The test invited foreign journalists from Malaysia, Thailand, and other countries. Future plans include steel-to-steel collision tests in Mexico and scratch tests in the Middle East. The Tiggo 8 CSH is Chery's latest model, equipped with plug-in hybrid technology "Chery Super Hybrid." It received 500 orders within one week of launch and sold 2,000 units within one month, priced at IDR 499 million.
