2018 Hyundai Ioniq Hybrid Review – Video

Hooray for innovation. Hyundai deleted the 12-V under-hood lead acid battery by carving out space in the under-seat-mounted li-ion battery’s space. Both conjoined li-ion batteries are covered under a lifetime failure warranty for original owners. Also nifty is should the 12V lose power, the high-voltage hybrid battery can jump start it via an in-car button.
