Battery Information About the Battery Discharging the Battery to 0% may permanently damage the Battery. To protect Model 3 has one of the most sophisticated against a complete discharge, Model 3 enters battery systems in the world. The most a low-power consumption mode when the important way to preserve the Battery is to charge level drops to 5%. In this mode, the LEAVE YOUR VEHICLE PLUGGED IN when Battery stops supporting the onboard you are not using it.

In this situation, contact Tesla. towing is required, the owner is responsible for towing expenses. Discharge-related towing Temperature Limits expenses are not covered under the Roadside For better long-term performance, avoid Assistance policy. exposing Model 3 to ambient temperatures The peak charging rate of the Battery may above 140° F (60° C) or below -22° F (-30° C) decrease slightly after a large number of DC for more than 24 hours at a time. Fast Charging sessions, such as those at Superchargers. To ensure maximum driving Energy Saving Feature range and Battery safety, the Battery charge Model 3 has an energy-saving feature that rate is decreased when the Battery is too cold, reduces the amount of energy being when the Battery†s charge is nearly full, and consumed when Model 3 is not in use.
