What size battery does a 2020–2025 Nissan Sentra take?

BCI group 35. Group size is a physical dimension and terminal-position standard, so a battery from a different group may not clamp down or may put the terminals on the wrong side.

The factory battery is a conventional flooded type. AGM is a valid upgrade, but never downgrade from AGM to flooded.

Engine bay, driver side.

Does a 2020–2025 Nissan Sentra need the battery registered after replacement?

No start-stop system, so a standard flooded Group 35 is correct; AGM is an acceptable upgrade. Typical replacements run 550–650 CCA.
