Looks like group 24 batteries are a perfect fit. Got one from Pep Boys (Bosch AGM 24) that measured 10" x 6.5" x 8" so identical to the Panasonic. The +- posts are in the exact same location as the Panasonic (group 24F (I guess F=flipped?) has the +- post reversed. Of course you can just turn the battery around but then the post will be further inwards in the compartment)

The group 24 installed perfectly in the Pep Boy's parking lot. The length is probably just a tad longer than the Panasonic and seem to not seat all the way to the bottom but pretty close. Once the L bracket goes on, its very firm and nothing moves.

The Bosch had a venting elbow on it (on the wrong side so I just swapped with the plug on the other side) Some batteries (Bosch AGM, Champion AGM) had them and some didn't. Looks like people just randomly pick them off as they need them.

For the temperature sensor, I used 2 zip ties to secure it against the L bracket. 1 to hold the white rubber sleeve the temp probe goes into. The other to prevent the round temp probe from sliding out of the rubber sleeve. See pics for reference.

Price was great. $195 - 25% instant rebate and another $40 master card rebate card so about $120+ when its all done.

OK, my 2009 TCH 12v is on the way out. If I check the vehicle signal diagnostic screen in the nav unit I get 11.6 v on ACC, 10.6v when ON, and 13.6-13.7 when running/ready. But that's only if I've driven it very recently. If I let it sit past 5-6 hours, I can't even get to the nav diagnostic check. Every time I flip the headlights on and off to bring up diagnostic menu. The whole system just reboots. However, the car seems to start to ready just fine for now.



Unfortunately for me, I don't have any Pep Boys around me. Anyhow, today I was at Walmart getting 2 new front tires put on and decided to see what they had in stock. I found that they carry their EverStart Brand AGM batteries with a 5 year warranty for $150. Does anyone around here have any experience with this brand? Do any of you guys think that this would be sufficient to replace the OEM battery? Also, it looked like it had vents on both sides. Or at least I'll assume that's what those holes on each side by the handles are. It looked like they had a little pin way down in the hole like a Schrader valve for a tire. I'll post some pics that I took of a Group 65 that that I saw on the shelf. Checking online they have some in Group 24F HERE. I just don't know what values are sufficient for the TCH as far as cold cranking amps, reserve capacity, and amp hours. And help and info is appreciated.

More than sufficient. Have at it. 12V you have does ZERO cranking. So this battery will last you years.

Thanks for the quick reply ukrkoz. The pics I posted were from a group 65, which I assume is a larger battery. So the sticker info might not be accurate for the group 24. From everything I've read, I know the cold cranking amps don't matter that much. However, what reserve capacity and amp hours would be sufficient? Before I buy it I want to make sure that it's the correct capacity.



Also, I know that the vent holes aren't all that important either, but do those look like they actually are vent holes? The group 24 might not even have them. But if it does, it might be another decent alternative for future forum people looking for TCH 12v alternatives.

Crank IS IRRELEVANT. This battery is NOT used for starting. So you should not be concerned with any cranking spec.
That battery is used aS POWER STORAGE FOR COMPUTERS, SOME OTHER ELECTRONICS. tHUS, POWER DEMAND IS RATHER VERY LOW AND YOU WILL BE FINE WITH THOSE SPECS.
Ooops, sorry, forgot caps were on. Or, finger hit Caps again.
I can't really tell from pictures if those are vent holes or not but, that being AGM, it will produce little to none hydrogene. Add to this it being in the trunk and trunk is not sealed tight, so little hydrogen or other gasses produced during normal function, will simply dissipate into the air.

Make sure to GENTLY transfer temperature sensor from your original battery to the new one and then tape it in place or else somehow secure it. It peals off the battery with minor effort.

Glad I decided to change the battery this afternoon. It was kind of temperamental to start this morning. Had to push the start button 4 times to get it to the "READY" mode. A few of the Christmas Tree lights on the dash flickered and Check VSC warning flashed a couple times. It was fine once I put it in gear and drove off though. I'll assume that's because once I shifted into gear the traction battery took over responsibility of powering the whole vehicle.


Anyhow, I got the Everstart Platinum AGM group 24F. One thing to note is that the terminals are reversed, so I had to flip the battery around. As far as size goes, the battery is slightly longer and taller than the OEM Panasonic battery. So much so that it doesn't sit in the tray flat and sits at a slight angle because one side is riding on the lip of the tray. Also, since the battery is a little bigger AND it's riding on that lip of the tray, the "L" bracket that holds that battery down didn't go down far enough for the bolt to reach the threads. Therefore, I had to stop at Home Depot and find a longer screw to secure the battery, only $1 though. And in case anyone is wondering, the bolt size and thread is metric M6 X 1.0, I think the one I got is about twice as long. Third picture below shows the older short bolt and the new longer bolt and package with UPC code.


As you can see from the pictures the vent tube and thermal sensor aren't attached to the battery. The Everstart has what looks like vents on each side of the battery. However, the coupler for the Panasonic is too big to fit into the hole of the Everstart. I have read that other brand AGM batteries with vents have smaller couplers. I may look for one, I may not. Doesn't really seem to matter too much from what I've read.



As for the thermal sensor. I was going to zip tie it to the bottom of the "L" bracket. But since the bracket was already tight because the battery was bigger and sitting higher, I didn't want to risk breaking the sensor from the force of the bracket against the battery. I just plugged it in and left it dangling in there. It seems that as long as it's plugged in, it won't throw any warning lights or messages. I may find a way to attach it to the battery, I may not. Again, it doesn't seem to matter much.


Then I unhooked the jumper cables from the positive jump terminal on the TCH and then the donor car. Hopped in and hit the button. Radio station presets and phone book info was all still there. I was surprised that I did get a master caution light and "Check Hybrid System" message. Not sure why, since I had back up power and all the other memory and presets held. No big deal though, 3 cycles of the start button cleared the message and master light.


After install, the new battery was reading the same as the old battery on the diagnostic signal check screen @ 11.8v. However, the sticker on the battery was 10/18, so I'll assume that it was a little discharged from sitting on the Walmart shelf. It was up to 12v on diagnostic screen after a 20-25 minute drive home though. I'll let it sit all weekend and see what the voltage is Monday morning. The car sat all last weekend and the old battery struggled last Monday morning.


I'll monitor it over the next few days/weeks and update here if there are any issues. Would any of you guys worry about mounting that thermal sensor? Does it really matter?

A "group" 24 and a 24F battery are the same except for the posts being reversed compared to the other....so buy the one that matches what you need.

These 2 styles/sizes of batteries have been around for 50 years....group 24 fits Chevy....and you guessed it....group 24F fits Ford….F doesn't stand for flipped. Chevy batteries were generally on the passenger side, as was the starter, and Fords were generally on the drivers side....as was the starter. Please don't spend all day looking for an example of those two generalities being different....it does not matter if you find one. I am talking about the 60's, 70's, 80's maybe even 90's.

True. But I don't think Ford uses 24F anymore (but not 100% sure).

Ford also at one time required a special ATF formula called Type F. I had a friend who took his 10+ year old Ford van to Jiffy Lube to get an oil change back about 1990, and they talked him into a transmission fluid change also. By 1990 Ford has stopped using Type F ATF, but the older Fords still required it. The high school kid working at Jiffy Lube who did the ATF change did not use Type F ATF on the older Ford van, and the transmission completely failed soon after that. Jiffy Lube denied all responsibility.

First, the OEM part should be 2880028061. Advantages include high quality / long life, comes with thermal sensor (no need to transfer from old), and vent tube will fit (though may not be that important for AGM batteries). Disadvantages include pricing and availability.

On https://parts.toyota.com/p/Toyota__Camry/BATTERY/63128553/2880028061.html, click on your nearest dealer(s) to see (online order) pricing (some dealers allow or require in-store pickup), or call around.

Second, the best non-OEM choice appears to Champion size 25 from Pepboys: https://www.pepboys.com/champion-agm-battery/product/2071655


Group sizes (if 25 is not available, you can decide if you want 35, 24F, or 51):
  • 25 should fit better than 24F, and has the correct terminal orientation. A car is designed for the positive terminal to be closest to the center of the car (the least chance of shorting out in an accident).
  • 35 is the same size as 25, but has the reversed terminal orientation that results in the positive terminal to be closer to the side of the car.
  • 24F is too long (see posts above), although AGM batteries do not need to be mounted flat/level. It has the same terminal orientation as 35 (reversed). Heavier.
  • 51 may fit even better than 25, and has the correct terminal orientation. But it is a smaller battery (less reserve capacity) really for the Prius.
Brands:
  • Champion from Pepboys, AutoCraft from Advance Auto, and EverStart from Walmart all look the same, and are made by Johnson Controls.
  • Bosch from Pepboys is made by Exide, and Pepboys appear to be phasing out Bosch for Champion. One advantage of Bosch is that the vent tube appears to fit (see first post). People seem to think Champion/Johnson Controls is of higher quality than Bosch/Exide.
  • Exide has bad reviews on Amazon, and there is a Youtube video titled "Why You Shouldn't Buy an Exide Edge AGM Battery" about problems getting warranty.
  • People seem to think Optima has quality control issues these days. There is a Scotty Kilmer video titled "Never Buy This Car Battery".
Pricing:
  • The Johnson Controls (non Optima) batteries are all about $150: Champion from Pepboys with automatic 25% on website, AutoCraft from Advance Auto (find coupon online), and EverStart from Walmart (no coupon needed).
  • They differ in what the click-through cashback sites offer.
  • Pepboys has been offering a $40 rebate for a while: https://pepboysrebates.rewardpromo.com/#/home/current-offers
Installation (removing the thermal sensor):
At the beginning of the video and in comments, it's a size 51.

"The Exide Edge Group 25 is of the same size as Group 35 but the terminals are correctly oriented for the Camry Hybrid on the Group 25 which keeps the positive terminal away from the body panel which is safer in the event of an accident.

"Thank you! The Bosch Group 35 AGM worked beautifully in my 2009 Hybrid
Camry. I tried the group 24 (it was too long) and the 25 wasn't available locally, but the 35 went right in. The existing bracket fit it nicely and the OEM vent tube plugged right on.
