What to know about Kia batteries

The catalogue covers 8 Kia electric models, on sale since 2014. The packs recorded use NMC cells, which largely decides how quickly capacity falls.

Battery warranty. The terms recorded for Kia range from 7 to 8 years, up to 100,000 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. 4 of the 8 models can be repaired module by module rather than by a full replacement, for between €500 and €2,500 depending on the model, whereas a new pack is priced at around €9,500 to €16,000. These are orders of magnitude recorded in France, never quotes.
