Battery Information
About the Battery Model X has one of the most sophisticated battery systems in the world. The most important way to preserve the 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. When plugged in, Model X wakes up when needed to automatically maintain a charge level that maximizes the lifetime of the Battery. 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 the Model X Battery becomes completely discharged in a situation in which towing is required, the owner is responsible for towing expenses. Discharge-related towing expenses are not covered 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.
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. On average, the Battery discharges at a rate of 1% per day. 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 discharges by approximately 14%.
Discharging the Battery to 0% may permanently damage the Battery. To protect against a complete discharge, Model X enters a low-power consumption mode when the charge level drops to 5%. In this mode, the Battery stops supporting the onboard electronics to slow the discharge rate to approximately 4% per month. Once this lowpower consumption mode is active, it is important to plug in Model X within two months to avoid Battery damage. Note: When the low-power consumption mode is active, the auxiliary 12V battery is no longer being charged and can completely discharge within 12 hours. In the unlikely event that this occurs, you may need to jump start or replace the 12V battery before you can charge. In this situation, contact Tesla. Temperature Limits For better long-term performance, avoid exposing Model X to ambient temperatures above 140° F (60° C) or below -22° F (-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 when Model X is not in use. Touch Controls > Displays > Energy Saving. For more information on maximizing range and saving energy, see Getting Maximum Range on page 71. 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 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 12V battery. Leaving Model X unplugged for an extended period can also result in permanent Battery damage. If you are unable to charge Model X, 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.
