The XV70 Camry made this job easier than the car it replaced: even the hybrid keeps its 12V battery under the hood, so there's no trunk trim or floor panel to pull. Everything is 10 mm — both terminal nuts and the two hold-down nuts — and the only real tool requirement beyond a basic ratchet is a deep socket and a long extension to reach down the side of the battery.
The thing people get wrong is the hold-down. Toyota uses two long threaded rods with J-hooks that latch into slots at the bottom of the tray; back the nut off without holding the rod and the hook drops into the tray where you can't reach it. Grab each rod with pliers as it frees up. The second mistake is fitting a cheap flooded battery to a hybrid — the hybrid needs a sealed AGM with the vent hose transferred over.
| Item | Type | |
|---|---|---|
| Ratchet 1/4 in drive (3/8 in also works) Drives the 10 mm socket for terminals and hold-down nuts. | Required | shop |
| Socket 10 mm, 6-point, deep, 1/4 in drive Fits both battery terminal nuts and the hold-down rod nuts. | Required | shop |
| Extensions 3 in and 6 in, 1/4 in drive Reaches the hold-down nuts down beside the battery case. | Required | shop |
| Combination wrench 10 mm Backup for the terminal nuts if a socket won't clear the fuse box or cover. | Recommended | shop |
| Socket 12 mm, 6-point Some cars have a 12 mm nut on the positive terminal clamp or battery tray bolts. | Recommended | shop |
| Flat screwdriver / trim tool Small flat blade Pops the positive terminal red cover and the plastic engine-bay cover clips. | Recommended | shop |
| Needle-nose pliers Standard Frees the hold-down J-hooks from the tray slots and pulls the AGM vent hose. | Recommended | shop |
| Battery terminal brush Post and clamp type Cleans corrosion off the cable clamps so the new battery reads full voltage. | Required | shop |
| Battery terminal cleaner spray Aerosol Dissolves acid residue on the tray and cable ends. | Consumables | shop |
| Anti-corrosion terminal grease or felt washers Dielectric/battery grease Applied after tightening to stop clamp corrosion. | Consumables | shop |
| Memory saver OBD-II port 12V memory saver Keeps radio presets, clock and learned settings alive while the battery is out. | Recommended | shop |
| Torque wrench 1/4 in drive, in-lb range Terminal and hold-down nuts are low-torque; overtightening cracks lead posts. | Recommended | shop |
| Battery carry strap Universal A 24F weighs around 40 lb and the fender lip makes it awkward. | Recommended | shop |
| Digital multimeter DC volts Confirms old battery is dead and new one charges (13.5-14.5 V running). | Recommended | shop |
| Replacement battery — gas models Group 24F, ~550-710 CCA Standard fitment for 2.5L A25A-FKS and 3.5L 2GR-FKS Camrys. | Parts | shop |
| Replacement battery — hybrid AGM auxiliary battery (Toyota S46B24R / Group 24 AGM equivalent) Hybrid uses a smaller sealed AGM with a vent port; do not fit a flooded battery. | Parts | shop |
| Nitrile or rubber gloves Chemical resistant Keeps acid and lead residue off your hands. | Safety | shop |
| Safety glasses ANSI Z87 Battery acid and sparks are eye hazards. | Safety | shop |
| Baking soda Small box Neutralizes any acid spill on the tray or paint. | Consumables | shop |
The 2.5L A25A-FKS and 3.5L 2GR-FKS use the same Group 24F flooded battery and identical 10 mm hardware; only the underhood routing around the battery differs slightly. The Camry Hybrid uses a smaller sealed AGM auxiliary battery (Toyota S46B24R type) with a vent hose and a plastic cover over it, but the same 10 mm terminals and J-hook hold-down. Some cars use a 12 mm nut on the positive clamp or tray bolts, so have that size handy.
| Battery terminal clamp nuts (10 mm) | verify in the service manual — typically hand-snug, about 45-60 in-lb (5-7 Nm); do not overtighten |
| Hold-down clamp rod nuts (10 mm) | verify in the service manual — snug only, roughly 60 in-lb (7 Nm); battery must not move by hand |
The 10 mm terminal and hold-down nuts and the Group 24F fitment for the 2.5L and 3.5L are well established for XV70; double-check your hybrid's exact AGM part number and battery-tray location against your own car and the owner's manual before buying, and confirm torque values in the FSM.
Unlike the previous-generation Camry Hybrid, which kept it in the trunk, the XV70 hybrid's 12V auxiliary battery is in the engine compartment under a plastic cover. It's a sealed AGM with a vent hose on the side that must be moved to the new battery.
Gas 2.5L and 3.5L models take a BCI Group 24F, typically around 550-710 CCA. The hybrid takes a smaller sealed AGM auxiliary battery (Toyota S46B24R / Group 24-size AGM equivalent) — not a flooded battery.
No. Toyota doesn't use battery management coding, so there's no scan tool registration like on BMW or Mercedes. You'll just need to reset the clock and radio presets, and possibly relearn the auto-up windows.
A 10 mm socket does both terminal nuts and both hold-down rod nuts; use a deep 10 mm with a 6-inch extension for the hold-down. Keep a 12 mm handy in case your car has a 12 mm positive clamp nut or tray bolts.
