Check for rust damage on the under frame also, read my experience at the bottom of this topic.

I just bought this 2012 Nissan Leaf.

What are the steps to take this battery out, clean it, and put it back?
What should I take extra notes of?
Alarm?
15mins after power off?
Losing all memories?
Thank you!

I took my time to replace the battery.
I clean the terminal connectors, add two anti-corrosive washers, and spray the terminals with anti-corrosive terminals spray.
Miraculously, I did not lose any memory.

Q: Is this a sealed battery or do you think there are holes under the sticker
for filling up with distilled water when it is low?

Check the fine print on the label, or look up the exact model, for the word "sealed."

The fact that you didn't lose settings is likely related to your not being able to clear those fault codes.

Looks good. If the sticker isn't made to be removed then the battery shouldn't need to be re-filled. Just keep it charged and it should last years, less in very hot climates but you'd know that by now if you lived in one.

The only settings I lost when replacing the batteries in my 2011 and 2015 were the auto up/down driver window control. Those functions are restored by opening the window and holding the control in the open position for a few seconds after the window is fully open. Then close the window and hold the control in the close position for a few seconds after the window is fully closed. To clear error codes, connecting a resistor or light bulb across the disconnected positive and negative cables to bleed voltage off (all of the electronic power supplies have capacitors in them) is needed unless the battery is disconnected for extended time so I am not surprised that radio settings were not lost.

It's advertised as a maintenance-free battery. There may or may not be hidden caps used for the original fill, but you shouldn't need to deal with them.
I noticed you're still working with polymers.

Good job on cleaning up the terminals, they look great.

There is no easy way to check the fluid level in "maintenance free" starter batteries, but it does have plugs under the label.
