my battery was dead after roughly 9 years of its manufacturing date (the battery was made in 2014). During covid era and in general, my car was rarely driven and I had the battery completely drain on me many times which I think probably affected its life - but it still lasted me this long. I purchased OEM from local toyota for roughly $300 OTD and just replaced it. Couldnt be more simple. New battery looks like it was manufactuered this year, so happy with that.
BTW purchasing these from a toyota dealer they WILL (at least in southern california) want you to provide a VIN or they will give you a real hard time or not even give you the battery - so just go ready to provide a dummy avalon hybrid VIN or something. the parts are exactly the same with the exact same part number on both toyota and lexus so idk why they make it such a big deal.

They say its to provide the accurate part but their system already lists two diferent batteries, and they have no idea which one is the right one. One for HS, Rav4, etc and one actually for the avalon and ES. Not sure if they are interchangeable but the exact part, as some others have already mentioned in this post, is the 28800-36050.

Good thing about these hybrids is that you can endlessly boost the battery to start the car as it does not need to have a charge once the car starts. So I was driving it for about a week until I could track down a battery using the boost to start the car every time. I obviously wouldnt recommend doing it but it is a work around in an emergency.

I bought Exide 24MX for my 2015 ES 300h. It did not come with the elbow. What do I do?
It also has two vent holes. What is the white stuff you used on the elbow and can I seat the second hole with any caulk?
Please advise.

Did your order of the 28800-36050 battery come with the vent hole? I'm looking on the Toyota parts website and it doesn't include the venting tube in the diagram for that battery... Strangely, it does exist on battery with part number 28800-28100 (which also looks more like the one you ordered).

Additionally, according to the website, apparently only the 28100 battery fits the 2013 Camry Hybrid but not the 36050 battery. Which should I order?
Is it just a mix-up on the site and I should be good ordering the OEM 36050 from Toyota (listed for the Camry Hybrid) for my 2013 ES 300h?

The Panasonic battery came with the vent hole

The OEM battery lasts a long time.
