How to change your dead battery on a LS600H?

[xanavi22]

I have drained my Battery using a tyre pressure pump running from the cig lighter.

I have brought a new Battery but after reading how to change it, it seems pretty complicated and dangerous, it is not like normal cars where u just disconnect both and connect back on?

Or with a LS600h, pull the safety plug out, disconnect both terminals, connect new Battery and safety plug back in?

Turn off ignition and change as normal.  The plug you are referring to is the hybrid Battery. Do not unplug. You could jump start the car and recharge it as normal.

Isn't there a temp sensor like in GS450h ? 

If it is and you won't move it you will end up with error on the dashboard.

This what u talking about?

Anyone know what to do with this hose pipe and clip above?

Yes that 2 wire cable looks like temp sensor connection. I know for GS peoples were just removing it from the old Battery (it was glues) and stick it to the new one with a tape.

Rubber hose is just standard vent which your Battery might have or not. I don't expect there is a sensor for that so I wouldn't  worry about that bit. Just use more tape to seal it if you don't have anywhere to connect it to.
