On the XA40 RAV4 the battery lives in the open at the driver-side front of the engine bay with nothing to remove first. Both cable clamps use 10 mm nuts, and the battery is held by a plastic bar across the top pulled down by two J-hook rods with 10 mm nuts. A 3/8 in ratchet, a 10 mm socket and a 6 in extension cover the whole job.
The usual mistakes are dropping the J-hook rods down into the tray area when the nuts come off, and cranking the hold-down nuts until the case flexes. Snug the bar just enough that the battery cannot shift by hand. This generation does not need battery registration or a scan tool, but you will lose the clock and radio presets unless you use a memory saver, and the power windows may need one full up-down cycle to relearn auto mode.

All 2013-2018 US-market RAV4s use the same 2.5 L 2AR-FE with the identical battery location and 10 mm hardware; the RAV4 Hybrid arrived in 2016 and places its 12V auxiliary battery in the cargo area on the right side behind the trim panel, which is a different procedure.

The 10 mm terminal and hold-down nut sizes and the Group 24F fitment are standard across 2013-2018 XA40 RAV4s with the 2AR-FE; confirm your exact group size against the label on the old battery or the parts counter lookup before buying.
The gas 2.5 L RAV4 uses a BCI Group 24F top-post battery, typically around 600-710 CCA. Check the label on the battery you pull out, since some vehicles leave the factory or a previous shop with a Group 35.
10 mm for both cable pinch nuts and for the two hold-down clamp nuts. A 3/8 in drive ratchet with a 6 in extension makes the hold-down nuts easy to reach.
No. The 2013-2018 RAV4 has no battery management registration requirement. You may need to reset the clock and radio presets and cycle each power window fully up and down once to restore auto operation.
The ECU loses its learned idle values and the window motors lose their limit positions. Let it idle a few minutes without load, and hold each window switch fully down then fully up and hold for a second at each end.
