Can this tool recalibrate a battery? Because mine(bought some weeks ago), below 30% drops almost immediately to 0% and it could be a problem in games like Pokemon

Lithium Ion batteries (most 3DS batteries fall under this) don't need recalibration due to not having charge memory. It is recommended to fully charge a new battery though.

This tool can't recalibrate a battery.
But you can recalibrate a battery with the following steps.
1, Turn off your 3DS
2, Open back cover
3, Remove a battery
4, Wait a few minutes
5, Reinstall a battery
6, Close back cover
7, Turn on your 3DS

can you explain what numbers I need to look at to know how healthy my battery is
Battery mark's result.

min 0m30s max 2m26s avg 1m17s total 1h49m23s
(used for 3 years)
min 1m15s max 3m27s avg 2m30s total 3h33m09s
(used for a few months)

Total noob here, and just dug up my 3ds.

any links on how to install an app like this?
Welcome to GBAtemp.

The primary source for this topic is https://3ds.hacks.guide/ This guide allows installing custom firmware on any 2|3DS console.
.cia files can be installed as standalone apps on the console with FBI and .3dsx are started with the Homebrew Launcher.
Take your time reading.

If you have any problems or any "noob" questions feel free to ask for help in the 3DS NOOB PARADISE.

Have fun!
