9. Summary

- Check battery voltage or electrolyte density when receiving new vehicles.

- Before vehicle delivery, check battery voltage or electrolyte density and starting capability. Same applies to new batteries before installation.

- Vehicles in storage and filled spare batteries:
Check battery voltage or electrolyte density periodically. Recharge if necessary. This does not apply to dry batteries until filled with electrolyte. Observe dry battery shelf life (24 month).

- Demo and showroom vehicles: Periodical preservation charging.

- Perform a battery service prior to a long parking/storage period (charging, electrolyte level, voltage test). Periodical preservation/maintenance charging.

- Before checking battery voltage observe battery rest times. Do not load the battery prior to checking voltage.

- Recharge discharged batteries immediately. Do not fast charge batteries. Determine cause for discharge.

- Use only Porsche approved batteries.



- Use digital measuring devices to check voltage and current draw. (Display accuracy.)

- Measured device for current draw should have a fused 4A range.

- When checking battery voltage, compensate for battery temperature (correction values for voltage and electrolyte density).

- Danger of explosion when connecting or disconnecting battery cables.
