* NNOOTE TE Accelerated aging of the high-volt-
age battery
As a result of its basic characteristics, the
storage capacity of, and the amount of energy
available from, the high-voltage battery
decreases over the course of its life. Due to
this, both the maximum electrical range that
can be achieved by the vehicle and its maxi-
mum electrical output can be impaired.
The following factors could accelerate the
aging of the high-voltage battery:
R
Frequently fully charging (charge level
100%) the high-voltage battery, especially
when this process is not directly followed
by a journey
R
Frequent rapid charging with direct current
(mode 4)
R
Leaving the vehicle idle for lengthy periods
at high ambient temperatures
#
To avoid accelerated aging, please
observe the following recommendations
when handling the high-voltage battery.
Recommendations when handling the high-voltage
battery:
R
Every six months, when the outside tempera-
ture is above 50 °F (10 °C), park the vehicle
overnight with a condition of charge below
20%.
R
Only charge the high-voltage battery with
direct current (mode 4) if necessary.
R
Charge the high-voltage battery on average to
a condition of charge of 80%. Beyond a condi-
tion of charge of 80%, the charging time is
considerably prolonged.
R
If leaving the vehicle idle for extended periods,
park the vehicle with the high-voltage battery
condition of charge at between 30% and 50%.
Do not keep the high-voltage battery continu-
ously connected to power supply equipment.
R
If leaving the vehicle idle for extended periods
of time avoid, if possible, high ambient tem-
peratures.
R
Check the high-voltage battery's condition of
charge every six weeks (
/
page 172).
R
Charge the high-voltage battery if the condi-
tion of charge is below 20%.
R
Do not disconnect the 12 V battery even if the
vehicle is le idle for an extended period. Oth-
erwise, the condition of the vehicle's high-volt-
age battery cannot be monitored.
You can contribute to reducing the vehicle's
energy consumption in the following ways:
R
An anticipatory driving style (

page 149)
R
Reduced use of electrical consumers
R
Having the vehicle regularly maintained
The charging time of the high-voltage battery may
change over the course of its life.
You can charge the high-voltage battery with both
alternating current (mode 2 or 3) and direct cur-
rent (mode 4).
