    Hi all,

    How long should you leave your Tesla plugged in? Going on a trip for a couple of weeks and wondered if it is fine to leave it plugged in during that time. Will it hurt or help the battery?

    Thanks

    Plug it in. Set the charge limit to somewhere in the middle, like 50-60%. Go about your day.

    From your Owner's Manual:

    "About the Battery

    Model S has one of the most sophisticated battery systems in the world. The most important way to preserve the Battery is to LEAVE YOUR Model S PLUGGED IN when you are not using it. This is particularly important if you are not planning to drive Model S for several weeks. When plugged in, Model S 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 S 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."

    Just don't set your charge limit any higher than 80%. There's also really no advantage to setting it lower.

    Doesn’t anyone RTFM any more? In the early days we had the owners manual memorized even before we got the car!

    I think the important thing we can share with our fellow inexperienced owners, is that they can read the manual online, or download the PDF to take with them on a mobile device. Some might not know this, and might not be able to sit in the car for long durations reading the manual.

    Here's the link --> Model S Owner's Manual

    That said, a quick search on Google does point to this question being resolved a magnitude of times (even links back to this site with great answers).
