About the Battery
Model 3 has one of the most sophisticated
battery systems in the world. The most
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 3 for several weeks. When plugged in,
you are not using it. This is particularly
important if you are not planning to drive
Model 3 for several weeks. When plugged in,
Model 3 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.

Battery Care
Never allow the Battery to fully discharge.
Even when Model 3 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

Discharging the Battery to 0% may
permanently damage the Battery. To protect
against a complete discharge, Model 3 enters
a low-power consumption mode when the
charge level drops to 5%. In this mode, the
Battery stops supporting the onboard

important to plug in Model 3 within two
months to avoid Battery damage.
Note: When the low-power consumption

longer being charged and can completely
discharge within 12 hours. In the unlikely event

Temperature Limits
For better long-term performance, avoid
exposing Model 3 to ambient temperatures
above 140° F (60° C) or below -22° F (-30° C)
for more than 24 hours at a time.
