Only 4% of the vehicles studied have had to change their battery due to loss of capacity over time. This analysis comes from Recurrent, a firm specializing in electric vehicle data analysis. In their previous study in 2023 with a smaller sample size of 15,000 cars, they found similar results.

The German Automobile Club (ADAC) has noted that the batteries in plug-in hybrid Mercedes vehicles degrade less compared to those from Mitsubishi. With updated data on over 30,000 electric cars, the analysis still shows a very low battery replacement rate—less than 4%. This includes older models with more than ten years of service.

It’s worth noting that most replacements have occurred due to manufacturing defects rather than natural degradation. Models like the Hyundai Kona Electric and Ford F-150 Lightning fall into this category, excluded from the general replacement percentage of just 4%. The study suggests normal battery life spans between ten to twenty years based on technology advancements.

Manufacturers typically offer eight-year warranties or up to 160,000 km (about 99,420 miles) for these batteries, replacing them if capacity drops below 70% of the original. Vehicles from 2011 to 2016 saw an 8.5% battery replacement rate compared to only 0.3% for models post-2022.
