URGENT UPDATE: Tesla owners with LG battery cells produced in China are facing alarming news: these batteries may fail up to 40% faster than their Panasonic counterparts. This revelation, confirmed by experts at the Croatian workshop EV Clinic, raises serious concerns for Model 3 and Model Y drivers relying on the NCM811 battery cells.
Recent analyses indicate that the nickel-manganese-cobalt (NCM) batteries from LG exhibit a significantly higher failure rate than those from Panasonic, impacting many vehicles in the European market. Experts warn that LG battery packs could reach the end of their service life around 240,000 kilometers, compared to Panasonic’s longevity of up to 400,000 kilometers.
The internal mechanics present a stark contrast: LG cells often show early signs of degradation, with internal resistance values exceeding 100 milliohms upon delivery, while healthy Panasonic batteries average around 10 milliohms. This discrepancy leads to overheating and premature failure, making repairs nearly impossible.
The financial implications are significant. EV Clinic reports losses exceeding 20,000 euros monthly due to extensive diagnostic work on these irreparable batteries. Customers are often left with no choice but to pay for expensive battery replacements directly from Tesla, which can reach five figures outside of warranty. The workshop has implemented special fees to assess repair feasibility, highlighting the growing operational crisis.
The situation has sparked urgent discussions among Tesla owners, many of whom are now seeking alternatives. Options include replacing defective batteries with used Panasonic packs, according to sources from Electrek.
As this developing story unfolds, Tesla owners are urged to monitor their battery performance and consider their options carefully. The implications for consumer safety and financial stability are profound, making it essential for affected drivers to stay informed.
Stay tuned for further updates on this critical issue affecting Tesla’s battery performance globally.
