I have a question regarding the battery in my 2010 450h. I've only had the car since August, and in my proactive maintenance efforts, I am trying to verify the age of the 12v battery. It is a Lexus sourced Panasonic D23 group with the correct part number for my vehicle, but I have not been able to locate any guide for reading the Panasonic battery date code. I cannot find any engaged codes on it... Just a stamped ink number above the label where it reveals that the battery came from a Lexus dealership.

The stamped number is 170310.

The battery looks brand new, but do does the test of the vehicle. If it is the original battery, I want to replace it now before it begins to give us trouble when we least expect.

Can someone tell me how to read the above code? If I had to guess, I would guess March 17, 2010, but I want to KNOW for certain.

Thank you.

EDIT on 02/01... after two days of waiting, I have to admit that I'm very disappointed in the absence of ANY response from Lexus CS. Perhaps my expectations are unrealistic, but I'm surely not feeling the "support" right now.

 

Never mind. I'll start a NEW thread with my question.
