Referring to a 75 A(h) - Porsche battery and the following preconditions:
| - | Battery capacity at least 80% (12.6V). |
| - | Constant current draw less than 25 m A. |
| - | Temperature above 0~ Celsius (32~ F). |
| - | Normal self-discharge (battery technically OK). |
A parking/storage time of 5 weeks with sufficient starting capability is obtainable. With temperatures below 0~ C (32~ F) parking time of 3 weeks with sufficient starting capability is obtainable.
The parking time is shorter for short distance vehicles and older pre-damaged (sulfated) batteries.
Prior to a longer planned parking /storage period, a battery service should be performed (charge, electrolyte density, battery voltage.)
