I recently purchased an '07 LS460L. Per Lexus Driver records the last two batteries lasted 18 mo and 22 mo respectively and were replaced by Lexus dealers (Lexus batteries). Has anyone found an after market battery that lasts longer? Anyone tried an AGM battery?

Batteries, these days, are essentially commodities. Typical batteries last 40 + months from the time the electrolyte is added. A very few batteries fail prematurely due to manufacturing defects but many last far beyond 40 months. The LS460s and LS600s have an undeserved reputation of being "hard on batteries" and you will see lots of CarFax reports with multi entries for "charging system checked" and "battery replaced." The vast majority of these problems are related to defective doorjamb switches which cause the headlight auto-off feature to not work. Other safety systems are compromised by defective doorjamb switches too. Here are some links that might be helpful:

AGM batteries have some advantages but in most situations with these cars the cost of AGM batteries is not justified.

I just replace my original battery that was almost 7 years old. The batteries should be lasting longer than this. Might want to have the electrical system checked out.

Yeah I agree. There is some kind of drain that's killing that battery prematurely.

Thanks. I'll check it out.

I think it's pretty situation dependent. If someone doesn't drive the car a lot and it drains down pretty far that's hard on the battery also which will cause it to fail sooner than later. For me as preventative maintenance I replace them no matter what every 4 years or so.

My 2008 with 65k miles still has it's original PANASONIC battery. Still works like a champ

I think a majority of LS owners treat these cars like garage queens which is very hard on batteries, then all the electronics on the car it takes its toll on the car. Batteries require extensive long commutes frequently or a trickle charge when not in use to remain at optimal use. My 600 with full LED and HID conversion and a sound system never gave me any issues but I replaced my battery as a precaution last year. 48-60 months max for any battery especially one like this.

Hot climates shorten battery life. My shop experience here in central Texas was OEM batteries easily lasted 3 years but the failure rate between 36 to 48 months was maybe 25%-35%. By 60 months, nearly all them were gone. My recommendation was to consider replacing any 4 year old battery since the odds of it failing within the next year was over 50%.

The OEM panasonic battery in my "07 LS made it to 51 months before it leaked.and got acid all over an electronic module under the battery tray. My parents had the car then and Lexus replaced that module. I'll be replacing my battery at 42 months, assuming it lasts that long.

I hate replacing things that don't need it. When mine dies, I'll replace it. My wifes Jeep Grand Cherokee (1994) battery lasted 10 years! When I traded in my 2003 7 series in January, it had it's original battery! So 11+ years and 80k miles and it was running and starting like new. The rest of the car was another story! LOL.

Had a Volvo S80 that I had to replace a headlight every 6 months. left side right side, they just kept blowing…AND other lights like parking and brake bulbs. BIG problems with that car…dumped it!!

You're older cars dont have a third of the electrical computers and uses that newer cars have so you can expect battery life to be the same. Just like smart phones. My old flip phone I charged maybe every 3 days. Now get by without charging a smart phone at least ONCE! I say 48-72 months MAX for your car before you replace it depending on how you take care of it. And no miles arent a good judge of that

Your car could be experiencing some kind of parasitic battery drain. If you are comfortable with a multimeter you could perform a parasitic draw test. Fairly simple to do as long as you are careful and follow best practices. I forgot where I saw this video (maybe it was on this forum) but it is a very good video demo on how to do this.
