Battery replacement assistance help
I have a 2008 LS460 LWB with 31,000 mile and even though my battery warranty doesn't expire
until next month, I've decided to replace it on my own as it seems to be laboring a bit.
Since I have two left hands and a small brain, are there any issues, suggestions, or tips to
changing out the battery that I need to know?
Do I have to reset anything or will all my settings be saved i.e. radio presets, TPMS, seat
memory, etc.
Any help would be appreciated.
Thanks,
Steve

I would never have some place change my battery for free.......who knows what they will do?
Plus, on a modern car you should always disconnect the negative first and reconnect it last.

Just push down on the clips..... It's real easy. Once you lift the plastic covers, there is one bolt holding the battery down. Just lift the tie down up and pull it out. Unhook terminals and swapped batterys.

I've changed my battery twice so far, and no issues in both times.
You may need a flat piece of metal to remove a couple clips on the lower end of the battery plastic cover whereas the clips on the upper end can be removed by pressing the clip to loosen it and take it out afterwards (if I remember correctly).
What to expect after the battery change?
Well, expect the radio, clock, seat memory settings to have gone briefly. In few minutes everything will go back to where it was before the battery change. Also you'll notice the rpm gauge will act differently for quite a while before it settles down. At least this is what happened with me in both times when I replaced my battery.
Last and most important thing I'd say is pick your battery wisely. Consider DuralLast Gold. Only if I could ship it to Saudi Arabia, I wouldn't be investing $100 and 4 hours of inconvenience every year on a damn inferior battery designed to last one day past the warranty.

The Owner's Manual says in a couple of places that the TPMS must be initialized if the battery is discharged or removed.
