A total of 156 vehicle series from around 20 car brands were evaluated in the current breakdown statistics. All breakdowns during 2023 that affected vehicles between three and ten years old (first registered from 2014 to 2021) were taken into account. In order to be used statistically, the series must have at least 7,000 registrations in two years . If this requirement is met, all vehicle model years with at least 5,000 registrations will be displayed.
For context they seem to be specifically referencing the 12V “starter” battery not the HV battery used for the traction drive in EVs with that 44.1% figure.
Additionally this figure seems to include all vehicles in the statistic, so some part of that is contributed by ICE vehicles.
in the currently evaluated year 2023 the battery accounts for 44.1 percent of breakdowns
3-10 year old combustion cars vs electric cars only having enough registered models to start observing their reliability in 2021
they explicitly only compared cars of the same ages, so only 3-4 years for both EV and gas powered

Every single time my ICE car broke down, it was the 12V battery.
