I never leave my car unlocked so locking it is not an issue.

Very easy to tell by putting an ammeter in series with negative lead of battery and check both ways for drain. Hopefully the receiver is waiting for a wake up signal and not constantly transmitting. The DCM is the big problem of battery drain and there have been numerous updates to address that for my 2020. I just had last one done 2 weeks ago and been 7 updates since I had it done 2 years ago. When I get a chance I am going to check the drain to see if any difference.

As an anecdote on the impact of a locked, garaged ES on the battery's charge level, during the initial period of COVID-2 California lock down my 2019 ES 350 was locked and parked in my garage for extended time periods one of which was 3 months or so. After 3 months, battery charge level was such that the car started up with no noticeable difference from if it has just been turned off a few minutes ago.

I purchased the car Oct '18, so under the 4 year warranty they replaced the battery Jan 2021 @13K miles, one dead cell.
Last week, the car didn't turn over on first crank, and then died in the parking lot of Home Depot. Fortunately it eventually started, so I went right over to Lexus.
Dead cell again, and even though the car is no longer under the manufacturers warranty (ended Oct '22) the battery was covered under its two year warranty.
Yes, I'm in Florida, but the car is garaged during daytime hours. Two years is not a very long life for a "premium battery."

Have you had the ECM update? There was a known software issue with the ECM causing it to drain the battery while the vehicle is off.

The ECM problem should not cause a cell to die.

My 2019 ES F Sport has been with me since March 2019 (2 more months to be 4 year-old), 61K miles now, I park it outside 90% of the time, in Atlanta GA, so it gets very hot in summer (4 months, I'd say 90 degree on average, there will be weeks where it will be 100-105 consistently, feel like 115, Jesus) and considerably (LOL) cold in winter (4 months, may hit 0 or negative few times with some snow LOL, but I'd say 30 - 50 most of the time).
My A/C never been switched off, always on auto. I plug my phone in 80% of the time for Apple Car Play.
I never have had any issue starting the car, or any battery issue, yet. Hope this helps....

) are on the road often and that for sure extends battery life.

On the forum for the ES battery drain, the problem seems to be prominent in 2020 models. I read through quite a few of them, and no one mentioned a 2019. I'll check with my servicelady.

Mine still has original battery and car lives outside. no problem so far (knock on wood). I will probably change it sometimes summer. For those that changed to non-oem one. Which one did you put in? If you like it, please share the link to website.

I'm a firm believer in buying OEM "premium batteries" due to their higher quality and being designed for that particular model. Over the last 20 years, I've purchased multiple Nissan and Volvo batteries from the dealer, and all got 7 to 8 years service here in coastal South Carolina. Some cars are garaged and others, not. And all cars are always locked whether in the garage or not.
My current Lexus GS350 battery was purchased at the dealer in September 2016. I'd be very upset with Lexus if my OEM battery lost a cell after 2 years.

Still blows my mind that in this current year we still have to wait for our car battery to die before we know it’s even low. C’mon car makers, help us out here!
