I'm at that stage. 07 350 with 41k. Still going strong bit when I look in the little window, I see yellow. The manual said suppose to look green. Also, I don't like how the aftermarket batteries looks. They tend to not have that little window. Good to know I can get it replaced for an oem under warranty.

I have a 1st-gen 2005 IS300 (bought new in late 2004) and the OEM Panasonic battery died over the weekend while it was parked in my garage. Triple A replaced the battery with their in-house branded Interstate (IIRC,Johnson Controls owns Interstate) model for about $120.
The Triple A mechanic was extremely impressed that the Lexus/Panasonic Battery lasted for seven years and stated that most car batteries should be replaced every 3-4 years depending on use/climate conditions. The mechanic added that it's more about the age of the car battery and if the car is equipped with other aftermarket audio/video/amp attachments that determine battery life rather than the mileage. He concluded by stating that based on his experience, the Lexus OEM batteries seemed to last the longest followed closely by BMW (Bosch?) batteries.
