12 volt battery for the Toyota Camry Hybrid 2007 to 2016
Picture of the the Optima Battery installed in a Camry Hybrid
Conclusion: We were recommending a Prius size battery for the Camry Hybrid because the electrical demands are very similar and hundreds of customers went this route and have been satisfied. Part of the reason we recommended this smaller size battery was there was no Optima battery available in the aftermarket that was the correct size and had a vent tube connection. The Prius battery is the same height. However, in the Exide line there is an AGM battery that is the same size and has a vent tube. You also have 2/3 more capacity for times when you leave a light on, sit in the car in Auxiliary mode, or leave the car parked for long periods of time. This battery also comes in a deep discharge variant but because it has so much capacity you should not be deep discharging it. Click here to see our recommended battery.
This battery also has the same vent tube hole so you do not have to worry about hydrogen, oxygen and sulfuric acid fumes in your car in the unlikely event that your car starts to over charge the battery.
We also provide instructions on installing the battery. It is actually very easy, however you do have to remove a temperature sensor from the old battery and tape it to the new battery You will save $150 dollars or more by doing this!

"Hi! I just wanted to report back that I received the battery and installed it. When I first powered up the car all of my lights came on and it would not start. I powered it down and when I once again pushed the start button it started like it should.
Thank you for saving me a small fortune on a replacement battery (if you remember the local Toyota dealer here on Guam wanted $923).
What is your physical mailing address. I'd like to send you a token of appreciation.

"Just wanted to thank you for supplying an Optima battery for my 2007 Camry hybrid. Delivery was quick, directions were very good and installation went very smoothly. You just saved me about $400, since the local Toyota dealer wanted $550 for the battery and installation. Great job - Thanks,"

"The battery arrived today, at around 5:30P. I unboxed the terrifically packed parcel and wrapped the temp sensor with the double stick temp tape. I stuck it to the top of the battery and encased it with hot glue. I also fastened the connector to the battery with hot glue. [Hot glue is optional.] Cleaned the battery terminals till it shined. Fastened the vent elbow into the battery vent hole. After all this, it popped right in and car is running again. Everything was done by 5:50P.
Wanted to thank you for the super service! Hope you continue servicing us hybrid owners, cause someone needs to prevent the dealer gouging. Really appreciated your help!

Understanding what is the best battery for a Toyota Camry Hybrid
First what does the battery do?
- Powers some electronics when your car is parked. It runs the security system, send and receives signals to and from the entry remotes, powers the clock, possibly powers part of the navigation system and might keep some memory stored in some of the computers depending on the model year.
Since these drains can continue for many hours while your car is parked the Toyota engineers have done everything they can to reduce them. If they did not you would always come back to a dead battery when you left your car parked for more than a few days.
How well did the engineers do?
Here are images of our amp meter showing the current draw after a door opening event on a Toyota 2007 Hybrid with smartkey and the navigation system and with doors unlocked: (we tried this several times and it was always the same)
If the entry remote control (fob) is near the car the amperage stays at this level.
At first, I thought the meter was disconnected so I did this over and over again and got the same readings each time. Now I realize with the doors unlocked the security system goes quiet and the key fob communications are not necessary because the doors are already unlocked once a door is opened the car will start attempting to communicate with the key kob so the ignition can be unlocked. When I tried this with a fob near the car the draw never went below .09 amps which explains why people end up with dead 12 volt batteries when they leave the fob in the car. If you park you car in a secure garage you can extend your battery life by never locking the car.
I also tried this on a 2005 Toyota Prius with smartkey and navigation and got similar results.
- The 12 volt battery also powers up all the 12 volt electronics when you go to start the car. All the computers in the car, the ignition system, any lights, fans, window heaters etc. All of this till you start the car but this is for less than a minute (to be explained) unless you turn on accessory mode and then you do not have the demands of the ignition system etc.
There is no alternator in a Camry Hybrid so how is the 12 volts system powered?
After the car has been started there is a ready display on the dash lights. This indicates that the high voltage system has been engaged and the car is ready to go. Part of the high voltage system is a high voltage to 14 volt converter system that powers the car and recharges the battery. This is on whether the gasoline engine is running or not. (We tested this on a Camry hybrid by measuring the voltage at the battery it goes to 14 volts as soon as you start the car, which is long before the gasoline engine actually starts.)
Once you start the car there is a "Ready" symbol displayed on the dash.
