What battery does a Toyota Camry use?
Toyota's 2027 Camry HV owner's manual puts the 12-volt battery in the right-hand side of the trunk. A replacement must have the same LN2 case size, with at least 55Ah (20-hour rate) and 345A CCA on cars without a moon roof or panoramic moon roof, or at least 60Ah and 563A CCA on cars with one.

From Toyota's 2027 Camry HV Owner's Manual (OM06325U), pages 389-391, 470-475 and 487, read November 10, 2026. The 2026 Camry HV manual for May 2026 and later production (OM06228U) lists the same location, sizes, ratings, voltage and charging rate. Check the manual that came with your car.
Where the battery is, and what to check
The manual says the Camry's 12-volt battery is located in the right-hand side of the trunk. Remove the 12-volt battery cover to see it.
On the outside of the battery, the manual says to make sure the terminals are not corroded and that there are no loose connections, cracks or loose clamps.
The battery discharges gradually even when the car is not used, through natural discharge and the draw of some electrical appliances, so a car left for a long time may not start. The manual notes the 12-volt battery recharges automatically while the hybrid system is operating.
How to jump start a Camry
If the 12-volt battery is discharged, the manual says you can restart the hybrid system with jumper cables and a second vehicle with a 12-volt battery, or call your Toyota dealer or a qualified repair shop. In short:
- Confirm that the electronic key is being carried.
- Open the hood and the fuse box cover, then open the exclusive jump starting terminal cover.
- Connect a positive cable clamp to the exclusive jump starting terminal on your Camry 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.
- Start the second vehicle's engine, raise its engine speed slightly and hold it there for about 5 minutes to recharge your Camry's 12-volt battery.
- Open and close any door of your Camry with the power switch off.
- Keeping the second vehicle's engine speed up, start the hybrid system by turning the power switch to ON, and make sure the READY indicator comes on. If it does not, contact your Toyota dealer.
- Once the hybrid system has started, remove the cables in the exact reverse order, close the terminal cover and refit the fuse box cover.
The manual says to have the vehicle inspected at your Toyota dealer as soon as possible once it starts. It also warns that the hybrid system cannot be started by push-starting, that the jump starting terminal cannot be used to jump start another vehicle, and that the alarm may sound and the doors may lock when you connect the cables. 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 bare 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:
Check the voltage
Turn the power switch off, wait 30 seconds with the high beam headlights on, turn the high beams off, then check. Open voltage should be 12.0 V or higher at 68°F (20°C); if it is lower, charge the battery.
Slow charge only
Charge at 5 A or less; the manual warns the battery may explode if charged at a quicker rate. Never charge it while the hybrid system is operating, and turn off all accessories.
Charge in the open
Charging produces flammable, explosive hydrogen gas. Charge in an open area, not a garage or closed room, disconnect the ground cable if the battery is still in the car, and keep the charger off while connecting and disconnecting it.
After reconnecting
The smart key may not unlock the doors right away, so use the remote or mechanical key. The manual says to start the hybrid system with the power switch in ACC; it may not start on the first try but should start normally from the second. Some systems may need initialization.
From Toyota's 2027 Camry HV Owner's Manual (OM06325U), read November 10, 2026. The manual also says to wear safety glasses, keep sparks and flames away and keep children away when working near the battery.
Replacing the Camry battery
The manual says to use a 12-volt battery designed for the Camry; the wrong battery can let hydrogen gas into the passenger compartment, causing a fire or explosion. It says to contact your Toyota dealer for replacement.
Its replacement requirements: the same case size as the previous battery (LN2), with a 20-hour rate capacity of 55Ah or greater and a CCA rating of 345A or greater on cars without a moon roof or panoramic moon roof, or 60Ah and 563A or greater on cars with one. A different size cannot be properly secured, and a lower capacity can let the battery go flat even if the car sits for a short time.
The manual also asks for a battery with a handle, and says the exhaust hose and exhaust hole plug must be firmly attached to the replacement battery's exhaust hole so gas cannot leak into the cabin. Removing the battery terminals clears information stored in the ECU, so the manual says to contact your Toyota dealer before removing them.

Toyota Camry battery FAQ
Where is the battery on a Toyota Camry?
Toyota's 2027 Camry HV owner's manual says the 12-volt battery is located in the right-hand side of the trunk, under a cover. For jump starting, the manual uses an exclusive jump starting terminal under the hood instead of the battery itself.
What size battery does a Camry need?
The manual says to use a replacement 12-volt battery with the same case size as the previous one (LN2). Without a moon roof or panoramic moon roof, it calls for a 20-hour rate capacity of 55Ah or greater and a CCA rating of 345A or greater; with a moon roof or panoramic moon roof, 60Ah or greater and 563A or greater.
How do I jump start a Camry hybrid?
Using a second vehicle with a 12-volt battery: open the hood and fuse box cover, open the exclusive jump starting terminal cover, and connect the cables to that terminal and to a metallic point as the manual shows. Run the second vehicle's engine a little above idle for about 5 minutes, open and close a door with the power switch off, then start your hybrid system and confirm the READY indicator comes on.
Can the Camry jump start another car?
No. The manual says the exclusive jump starting terminal is for charging the 12-volt battery from another vehicle in an emergency and cannot be used to jump start another vehicle. It also says the hybrid system cannot be started by push-starting.
What voltage should a Camry battery have?
The manual lists an open voltage of 12.0 V or higher at 68°F (20°C), measured after turning the power switch off, waiting 30 seconds with the high beams on, then turning the high beams off. If it is lower, charge the battery, at a charging rate of 5 A max.
Is the 12-volt battery the same as the hybrid battery?
No. The 12-volt battery covered here powers the car's electrical systems and is what goes flat if the car sits. It recharges automatically while the hybrid system is operating. The hybrid (traction) battery is a separate part of the hybrid system.
