high charging voltage and excessively high charging
current. This can damage the battery and irritating
gases can escape. This can cause considerable
damage to the vehicle and chemical burns.

e Only use chargers that have been approved by
the equipment manufacturer for LiFePO
teries with integrated electronic protection
circuits.
e The following maximum values must never be
exceeded:
– Max. charging voltage: 14.8 V (even in the
event of a fault with battery disconnected; no
voltage peaks permitted)
– Max. charging current: 90 A
e If in doubt, contact an authorized Porsche dealer.
e Observe the instructions of the charger
manufacturer.
e Batteries should only be charged in a well venti-
lated area.
