Which Toyota Highlander model years does this cover?

These battery specifications apply to every Toyota Highlander built from 2020 through 2025 — the XU70 (4th generation), mid-size 3-row crossover suv (tnga-k platform). Nothing in this specification changes between those model years. Pick your year for the engines it offered, what changed that year, and the problems recorded against it.

What size battery does a 2020–2025 Toyota Highlander take?

BCI group H6 (LN3) EFB. 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.

Does the 2020–2025 Toyota Highlander need an AGM battery?

The factory battery is an EFB type. Match the type when you replace it.

Where is the battery on a 2020–2025 Toyota Highlander?

Engine bay, driver side.

Does a 2020–2025 Toyota Highlander need the battery registered after replacement?

Gas models have stop-start; Toyota specifies an H6 (LN3) EFB, replace with an EFB or AGM of the same size, not a plain flooded battery, or stop-start and battery life suffer. The Toyota chart covers the 2020+ V6 explicitly; the 2023+ 2.4T uses the same H6 fitment. Hybrids use a trunk-mounted H5 AGM instead (see hybrid engine entry).
