High Voltage Battery Information
About the High Voltage Battery
Model X has one of the most sophisticated battery
systems in the world. The most important way to
preserve the high voltage Battery is to LEAVE YOUR
VEHICLE PLUGGED IN when you are not using it. This is
particularly important if you are not planning to drive
Model X for several weeks.
NOTE: When left idle and unplugged, your vehicle
periodically uses energy from the Battery for system
tests and recharging the low voltage battery when
necessary.
There is no advantage to waiting until the Battery's level
is low before charging. In fact, the Battery performs best
when charged regularly.
NOTE: If you allow the Battery to discharge to 0%, other
components may become damaged or require
replacement (for example, the low voltage battery). In
these cases, you are responsible for repair and/or
transporting expenses. Discharge-related expenses are
not covered by the warranty or under the Roadside
Assistance policy.
The peak charging rate of the Battery may decrease
slightly after a large number of DC Fast Charging
sessions, such as those at Superchargers. To ensure
maximum driving range and Battery safety, the Battery
charge rate is decreased when the Battery is too cold,
when the Battery's charge is nearly full, and when the
Battery conditions change with usage and age. These
changes in the condition of the Battery are driven by
battery physics and may increase the total
Supercharging duration by a few minutes over time. You
can minimize the amount of charge time by using Trip
Planner to warm the Battery while driving to a
Supercharger. See
Trip Planner on page 154
information.
Battery Care
Never allow the Battery to fully discharge. Even when
Model X is not being driven, its Battery discharges very
slowly to power the onboard electronics. The Battery
can discharge at a rate of approximately 1% per day,
though the discharge rate may vary depending on
environmental factors (such as cold weather), vehicle
configuration, and your selected settings on the
touchscreen. Situations can arise in which you must
leave Model X unplugged for an extended period of time
(for example, at an airport when traveling). In these
situations, keep the 1% in mind to ensure that you leave
the Battery with a sufficient charge level. For example,
over a two week period (14 days), the Battery may
discharge by approximately 14%.
Discharging the Battery to 0% may result in damage to
vehicle components. To protect against a complete
discharge, Model X enters a low-power consumption
mode when the displayed charge level drops to
approximately 0%. In this mode, the Battery stops
182
supporting the onboard electronics and auxiliary low
voltage battery. Once this low-power consumption
mode is active, immediately plug in Model X to prevent a
jump-start and low voltage battery replacement.
NOTE: If Model X is unresponsive and does not unlock,
open, or charge, the low voltage battery may be
discharged. In this situation, try jump starting the low
voltage battery (see
page 219
battery). If the vehicle is still unresponsive, contact Tesla.
Temperature Limits
For better long-term performance, avoid exposing
Model X to ambient temperatures above 60° C or below
-30° C for more than 24 hours at a time.
Energy Saving Feature
Model X has an energy-saving feature that reduces the
amount of energy being consumed by the displays when
Model X is not in use. On newer vehicles, this feature is
automated to provide an optimal level of energy saving.
However, on older vehicles, you can control the amount
of energy being consumed by the displays by touching
Controls > Display > Energy Saving. For more
information on maximizing range and saving energy, see

Battery Warnings and Cautions
WARNING: The Battery has no parts that an owner
or a non-Tesla authorized service technician can
service. Under no circumstances should you open
or tamper with the Battery. Always contact Tesla
for more
to arrange for Battery servicing.
CAUTION: If the Battery's charge level falls to 0%,
you must plug it in. If you leave it unplugged for an
extended period, it may not be possible to charge
or use Model X without jump starting or replacing
the low voltage battery. Leaving Model X
unplugged for an extended period can also result
in permanent Battery damage. If you are unable to
charge Model X after attempting to jump start the
low voltage battery, contact Tesla immediately.
CAUTION: The Battery requires no owner
maintenance. Do not remove the coolant filler cap
and do not add fluid. If the instrument panel warns
you that the fluid level is low, contact Tesla
immediately.
CAUTION: Do not use the Battery as a stationary
power source. Doing so voids the warranty.
