Lexus Is200 seems completely dead

[Blathers]

Hi there, currently having an issue with my car (is200, 2001 spec) 

Don't drive it often so I find it dead most days and have to charge it before I can use it. After charging one time, I've left it, and when I've now gone back to it, it seems completely dead, like no lights or anything. All is fine after removing charger when hooked up to mains, car showing full voltage and a full Christmas tree of lights, but after trying to start the car, all the lights go off, doesn't even try and start the car, complete silence apart from a small beeping sound... 

Any ideas would be great as I can't even lock the car anymore 😬

Thanks 🙂

Interesting as the chargers reading full, car is and only 1 or 2 days ago charged it for a good 6-8 hrs so I've put it on again so if that changes anything

You don't mean dead as in needs a new Battery tho do you? Only got one about 6 months ago!
