I had two lexus batteries die on me within short span (did not remember how long) but got covered only 50% of the cost.

based on your experience, it seems that the battery warranty goes with the car, and not with the owner, i.e., change of owner does not affect the warranty. that's good, Thanks,

I own an 07 and recently had to make a trip to the dealer for a few things.
While it was in their care, they tested the battery and said that it failed the load test and that I needed a new battery.
I approved to replacement, about $220 if I recall correctly.
I asked if the battery was the original Panny (I couldn't recall from my service record's) and he said he'd have to check.
He came back and said that it was the original and that he was surprised, as that would indicate that the battery is over 8 years old, as my car was placed into service in early September of '07.
He also said that it seems that, based off of his observations, that Lexus OEM batteries seems to fare better in colder climates, versus warmer climates (He has been a SA for Lexus in NY as well as in the south).
He said in the warmer climates, the batteries seems to have a life of about 4-5 years where up north it was closer to 7-8.
He thinks the heat drains them...
Just though I'd share his perspective.

I just replaced the original in my 2007 about 3 months ago. Very impressed!

The original Lexus battery was dead when I went to test drive my '10 460 and the dealership replaced it with a new Lexus battery in my presence. That new battery lasted a little over a year. I replaced that Lexus battery with a Interstate over three years ago and no problems to date. I think some battery are just better than others. I've used Interstate battery on most of my vehicles and they last a long time.

My original Panny lasted over 6 years, I replaced it with an AC Delco Professional 2 years ago. I paid about a hundred bucks on sale.

Welp... my OEM Lexus battery installed in April (shortly before I bought the car in July) was dead this morning. Car hadn't been driven in 12 days. Headlight switch was OFF. Had to run three blocks to the garage where my old Acura is parked and drive it to my off-site meeting.

Will try tonight to jump it and get the car moving, but I'm thinking the next battery is not going to be an OEM one.

So, what exactly is it about this car that seems to drain the battery when its not driven?
I'll be honest in saying that I was a bit saddened to find out that my Panny failed the load test, because all I could think about was the new "OEM" interstate batteries failing prematurely.
I had planned on driving my Honda for most of the winter and letting the LS stay in the garage, while only driving it occasionally.
But now I'm wondering if that wont be good for the battery.

CRowe14, I think both you and I need battery tenders for this car. My car gets driven on most, but not all, weekends, and on a weekday maybe once every six weeks. It's fairly normal for it to sit for two weeks like it did immediately before today's dead battery event.

A jump from my Acura took care of the issue for the moment (with a spluttery hiccupy start as the ECU tried to get its bearings), but I know this battery's on borrowed time and will be looking around for a new one this weekend (and driving the car every day until I get one).

Just an update: I finally got off my duff and replaced my failing Lexus battery over the weekend. I bought a DuraLast Gold DLG-24, which fit perfectly and started the car on the first try. Spent way too much time dealing with the stupid fiddly rod on the front side of the battery tray, but other than that battery replacement was as easy as expected.

Will update when it inevitably fails.

I removed my FIDDLY ROD over the weekend to remove the top hold down and check the levels in the cells. What a pain. I finally removed the battery so I could understand how to get it back in place! Those slots at the end of the rod are deceiving.

I, too, just ate a OEM replacement battery in less than 6 months. It replaced a battery that was less than 3 years old. This time, the Toyota dealer I had it towed to (VSC System Failure, Brake Failure, World Ending, yada yada) determine the alternator was toast. CPO warranty covered the alternator ($1675 parts & labor) but not the $30 freight to the dealer or the battery that lasted less than 6 months due to the alternator being on its last leg? Seems silly, but whatever.

Sometimes that extended CPO warranty does pay off.

Also, time to find the paperwork on the 6 month old battery and see about getting its replacement cost covered.

Checking back in / dredging up the thread. I'm still on the original Panasonic battery. 7 years of service (the car began service 12/09). The car still cranks, but it distinctly sounds weak. And since I do not prefer to get stranded at one of my several mistresses homes (), and the battery IS 7 years old, I just purchased a new battery. A NAPA "The Legend" - Premium.

I'm adding a few blurbs of information for future searches. I read about flooded cell batteries and the East Penn / Deka (NAPA) 84 series always rates well. And it was accessible to me. So I purchased an 8424. 725 CCA and $108. Manufactured in September this year. It's an 84 month warranty (18 months free replacement, the remainder pro-rated) from the PURCHASE date (not manufacturing date). Hence the 84 series name.

It is a size group code 24 (BCI). It took me forever to find the group code on here! I don't trust auto parts stores (but they did have it correct). It may go in tonight, it may go in tomorrow.

Why do I get so excited about silly stuff like car batteries? I think that makes me an auto-nerd.

LOL. That's why we're here!

I can think of so many things that are much, much worse to identify with!
