I'm jetting out on a business/pleasure trip. Plan on leaving ED at the airport for two weeks. Probably have 80-90% soc when I get to the airport. Do you think I will have a battery problem when I return? I can't imagine trying to get ED charged at the airport.

Now that temperatures have warmed up, you have very little to worry about.

However, if you were asking the same question in cold temperatures (well below 0 Celcius), then the answer might be a bit different.

The manual has some limited advice on this:

High or low outside temperatures
The efficiency of the high-voltage battery
is temperature-dependent and decreases
at high or low temperatures. Additionally,
the electrolytes used can gel at very low
You can check the maximum capacity avail-
able using the indicator in the multifunc-
tion display .
Energy consumption and range
The available energy of the high-voltage
battery is reduced by:
- low
outside temperatures
-switching on electrical consumers
At low temperatures and after being parked
for an extended period without charging,
the physical properties of the high-volt-
age battery:
- can cause a significant reduction in the
performance of the battery
- can lead to longer charging times

In extreme cases, you will not be able to
start the vehicle. For this reason, always
connect the charging cable or make sure the
battery is completely charged when park-
ing the vehicle in low outside tempera-
tures or for an extended period of time.

Notes on battery care

Avoid storing and transporting the vehicle
at high temperatures for extended periods
of time (e. g. container transport).
When out of use for longer periods of time,
connect the vehicle to a voltage supply.
If the vehicle is not connected to a voltage
supply, it must remain within a tempera-ture range from -20C to 40C.
When the vehicle is exposed to tempera-
tures below -25C for longer than
seven days, irreversible damage by frost
can occur.

heh, if it were an ICE you'd likely need a jump after two weeks.

Hey, your battery is a 'little' bigger.

There are two different batteries in the smart ed. There is a 12 volt battery that is much like a standard ice car battery. There is also the big power train battery. But in correctly functioning ice car, you should be able to leave the car unattended for at least a month without issue.

The only time I have ever had issues with an ice car and not being able to start it was when the battery was near the end of its life.

One car I own that I do got drive very much will sit for at least three weeks some times. It has no issues starting up perfectly even after sitting there. This is a 2003 inline 6 s-80

Otoh another car I own if I do not start it at least every two weeks, the battery will be dead. This is 2009 Subaru with a new battery. It just seems to have some sort of power drain.
