If you have a 2013, or 2014 GS and your battery has died, you may want to look at this: http://www.revbase.com/BBBMotor/TSb/...dPdf?id=195332

Are you posting because your battery has died after a short period of sitting, or just a general question? If a general question, you should be fine for a couple weeks and more.

On several occasions, I have left my 2013 GS350 undriven for five to six weeks while I was on vacation, must recently last June. Never had a problem, much to my surprise. My battery is the original one from the factory, BTW.

There's a difference in how long it could, should, or will hold its charge. My owner's manual specifically specs the length of time that it should be okay as a "long time."
I consider ~ 6-8 weeks as a reasonable expectation. There is a TSB for some '13 and '14 models that the ECU may not properly go into a low-power state, and drains the battery too quickly.
Naturally how long you can go is a function of how fully charged your battery was. If you made a pile of short trips in cold weather, your battery is much less likely to be well charged than if you recently completed a fairly lengthy drive.
If the vehicle is left for a long time, the battery may discharge, and the engine may be unable to start.

I seem to recall there were some ****ty batteries that came with some Lexus vehicles at this time, too. My mother's '13 ES350 was afflicted by this "battery dies too fast" BS, (if she left the car sit for a week and a half it would refuse to start) and then after her last visit to the dealer it mysteriously went away. I think they gave her an ECU reflash/replace and/or replaced her battery without saying they did, I think this was a huge embarrassment to the brand and some dealers.

I've noticed batteries in general appear to have gone downhill, especially with their tolerance of higher trickle drains. I've had 3 different cars, all from 3 different manufacturers, now that end up requiring battery changes approximately every 2 years. I had another car that went on average 6 years between battery changes, and that was in the same climate with arguably worse driving habits -- it was a lower-tech car with probably 0 drain when the engine was off.
