Normally I wouldn't ask, but I haven't change the battery on an SC before and I'm flying down to pick one up and will be swapping batteries first thing so I need to bring with me what I need.

I assume a 10mm box wrench and a 1/4 inch drive with a 10mm socket should do? Do I need a deep socket? And extension?

I have 10mm nuts securing bar that holds down the plastic battery box.

The strange thing is I have different sized nuts on the terminals. 12mm on one side and 13mm on the other (iirc... might be 10mm & 11mm, or 11mm & 12mm or, 12mm & 13mm).

So, take all 4 to cover 10-13mm and you should be fine. I prefer spanners to sockets for the terminals but that's just me.

sometimes you need a deep socket depending on the terminal bolt sizes.

you could also just use an adjustable wrench for all the bolts.

@Scarletti mine were both 12mm.

Why not jump the car to start it and take it to a auto parts store and they will change it out for you? I am not sure but is there a core charge on batteries these days? Plus you would not have to mess with returning the old battery

10 mm for both.

Also a piece of tape to keep that gdmned long, retainer hook from dropping out of position! Every time, that is the most frustrating aspect of swapping out the SC430 battery.
Yes, a deep socket is useful for the job.

One thing that I observed when I recently purchased my 2005 -- when the previous owner replaced the battery -- the memory seats no longer worked. There's a very interesting series of steps you need to take to reinitiate the memory seats. You can find it on YouTube.
