What to know about Hyundai batteries

The catalogue covers 6 Hyundai electric models, on sale since 2016. The packs recorded use NMC cells, which largely decides how quickly capacity falls.

Battery warranty. The terms recorded for Hyundai are 8 years, up to 100,000 to 125,000 miles, with a guaranteed minimum capacity of 70%. These terms depend on the date of first registration, not on the model alone: the checker gives the end date for a specific car.

Cost of a failure. 3 of the 6 models can be repaired module by module rather than by a full replacement, for between €600 and €2,500 depending on the model, whereas a new pack is priced at around €11,000 to €16,500. These are orders of magnitude recorded in France, never quotes.
