Changing Car Battery On Gs430

[mixls400]

Hi, as the title suggests, the Battery on my 2005 GS430 is starting to loose its charge after a couple of days. I'm assuming its the Battery itself so was wondering if its ok to disconnect it to change it or will the stereo need recoding as I cant find one in the cars history folder ?

I will be fine to change the Battery.

Michael, I use an Accumate charger for my car, it keeps the Battery charged whilst the car is not in use. Have used it for years on a number of cars and it's proved invaluable.

I changed mine recently no issues other than the electric windows wouldn't move. Looked it up on the forum and was a easy fix. If I remember rightly somthing like holding the window switch on the specific door for a number of seconds.
