Moderators.. I've noticed that the postings are getting off topic. Maybe we've gotten all the input on this narrow subject we can. As the thread starter, I'd like to close this thread. Thank you.

Probably made by Johnson Controls in Mexico like about every brand of battery for sale in the US. Even fabled Optima Red Tops are made by JC in Mexico now. I buy based only off of price and CCA ratings, I don't even care what the brand is anymore with them all being from the same place.

I recently had my 2020 ES at the Lexus dealer for a problem with the Enform system (which I will start another thread about), so I asked the service writer who manufactures their batteries and he told me it's made by Interstate. Can't vouch for the accuracy of that statement but that is what I was told.

This is a Japanese battery manufacturer. If you look at their battery models they list the ENJ-380LN3 for Lexus.

My 2020 ES350 is at the dealer now for this issue. This is the second time. I purchased the car in December and they replaced the battery in February...the car has just over 2,000 miles on it. I'm not driving as much ...COVID...but I am driving probably every other day. They have not mentioned the lack of driving as being an issue. They mentioned the location of the keys when not using car. They have turned it over to their "technical" task force. We'll see what they say. I had an ES350 prior to this one and never had a problem, although it was a 2010. I sure hope this is not going to be an ongoing problem. I too worry about getting stranded.

I got the car back yesterday afternoon. The battery was fine. They think I am keeping my spare key too close to the car. I keep it just inside the attached garage door..about 10 feet from the car. They claim every time the garage door to the house is open the key that is right inside the door connects with the car and starts the computer...wearing the battery down. They did say they have had others with the same issue ...which I have seen online. I'm not sure what to think but we will see how it goes since I have moved the spare key to the front of the house. Keep your fingers crossed. I absolutely love this car and had zero problems with the other two Lexus cars I have had...I would be so disappointed if there is something else wrong with it.

I wonder why the key too close problem is only with 2020. It could still be that your first battery was bad as well as the second battery. They wouldn't replace them unless they failed battery tester.

2020 ES 350 Ultra Luxury model about 4 mos old. Car died and would not start, everything dead. Was able to jump start drove to dealer. After one day was contacted by dealer who stated they did not know what the cause is and Lexus Corporate will be looking into it. Will post update when I get one. Very weird. Have owned Lexus’ for over 30 years and have never had a problem beyond routine maintenance.

Here is the update from yesterday's reply to the Battery Drain issue. My service advisor called to advise that there was a "bad computer" which caused the car to die. Part has been ordered and will be replaced on Monday. Still very weird has anyone else experienced this. TY
