Hyundai IONIQ 5 Battery Replacement Phuket | 12V Battery Guide
Hyundai IONIQ 5 is a hugely popular EV in Thailand, featuring retro-futuristic design, 800V E-GMP architecture for industry-leading charge speed (18 mins 10-80%), and a 72.6 kWh battery delivering 481 km range. But IONIQ 5’s small 12V AGM battery still controls everything — if it dies, you can’t unlock doors and your premium EV becomes a paperweight.
