5.3 Reference Values For Battery Discharge/Parking Time

Referring to a 75 A(h) - Porsche battery and the following preconditions:

- Battery capacity at least 80% (12.6V or 1.24 g/ml).
- 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.)
