Number of possible breakdowns x (actual & calculated cost per breakdown + penalty per breakdown) = breakdown cost

The number of breakdowns to be considered is a statistical average value calculated from the use-related service life of an improperly used battery technology and the specified operating time of the vehicle. An improperly used battery reaches the end of its service life prematurely and causes breakdowns more frequently:

In case of AGM technology recommendation

expected 2 breakdowns per year when using conventional batteries.
expected 1 breakdown per year when using EFB batteries.

In case of EFB technology recommendation

vexpected 1 breakdown per year if conventional batteries are used

The actual and calculated costs (e.g. downtime, towing costs, etc.) are set at {breakdownCost} per breakdown. Contractual penalties due to possible delays in delivery, etc. are set at {penaltyCost} per breakdown.
