RAV4 Hybrid 12-volt battery specifications

From Toyota's RAV4 Hybrid Owner's Manual (OM0R032U), pages 505, 579-584 and 597, read November 10, 2026. If you drive a RAV4 Plug-in Hybrid or an earlier RAV4, check the manual that came with your vehicle.

Where the battery is

The manual says the RAV4 Hybrid's 12-volt battery is located in the right-hand side of the luggage compartment, not under the hood. Under the hood, inside the fuse box cover, is the exclusive jump starting terminal used to charge the battery from another vehicle in an emergency.

The battery discharges gradually even when the vehicle is not in use, through natural discharge and the draw of certain electrical appliances, so a vehicle left for a long time may not start. The manual notes the 12-volt battery recharges automatically while the hybrid system is operating.

To help prevent a flat battery, the manual says to turn off the headlights, air conditioning and audio system while the hybrid system is off, and to turn off unnecessary electrical components when driving at low speed for a long time, such as in heavy traffic.

How to jump start a RAV4 Hybrid

If the 12-volt battery is discharged, the manual says you can restart the hybrid system with jumper (or booster) cables and a second vehicle with a 12-volt battery, or call your Toyota dealer or a qualified repair shop. In short:

1. Vehicles with alarm: confirm that the key is being carried.
2. Open the hood and the fuse box cover.
3. Open the exclusive jump starting terminal cover.
4. Connect a positive cable clamp to the exclusive jump starting terminal on your RAV4 and the other end to the positive (+) terminal on the second vehicle. Connect a negative cable clamp to the negative (-) terminal on the second vehicle and the other end to the metallic point shown in the manual.
5. Start the second vehicle's engine, increase its engine speed slightly and hold it there for about 5 minutes to recharge your RAV4's 12-volt battery.
6. Keeping the second vehicle's engine speed up, start the hybrid system by turning the power switch to ON.
7. Make sure the READY indicator comes on. If it does not, contact your Toyota dealer.
8. Once the hybrid system has started, remove the cables in the exact reverse order from which they were connected.
9. Close the exclusive jump starting terminal cover and reinstall the fuse box cover.

The manual says to have the vehicle inspected at your Toyota dealer as soon as possible once the hybrid system starts. It also says the hybrid system cannot be started by push-starting, the jump starting terminal cannot be used to jump start another vehicle, the alarm may activate and the doors may lock when you connect the cables, and the cables must not become entangled in the cooling fan. To avoid igniting battery gas, the manual says to make sure each cable is on the correct terminal, keep the other end of the cable on the + terminal away from other parts and metal surfaces such as brackets or unpainted metal, never let the + and - clamps touch, and keep smoking, matches, lighters and open flame away from the battery.

Checking and charging the battery

From the owner's manual:

From Toyota's RAV4 Hybrid Owner's Manual (OM0R032U), read November 10, 2026. The manual also says to wear safety glasses, avoid sparks from tools touching the terminals, not lean over the battery and keep children away when working near it.

Replacing the RAV4 Hybrid battery

The manual's replacement requirements: a 12-volt battery with the same case size as the previous one (LN2), a 20-hour rate capacity (20HR) of 55Ah or greater and a performance rating (CCA) of 345A or greater. It should be a Central Degassing type that conforms to European regulations, with a handle; without a handle, removal is more difficult.

If the size differs, the battery cannot be properly secured. If the 20-hour rate capacity is low, the battery may discharge even if the vehicle sits for a short time, and the hybrid system may not start. An improper battery can reduce battery performance, and the hybrid system may not be able to restart.

After replacing, the manual says to firmly attach the exhaust hose and the exhaust hole plug to the new battery's exhaust hole; if they are not properly installed, hydrogen gas may leak into the vehicle interior and could ignite and explode. When removing the battery terminals, always remove the negative (-) terminal first, and do not disconnect the negative (-) terminal on the body side, because it may touch the positive (+) terminal and cause a short. Removing the terminals clears information stored in the ECU, so the manual says to contact your Toyota dealer before removing them and for information on battery replacement.
