As of today my OEM battery in my 2003 Tundra has lasted 5 1/2 years. It just died on my son this morning.
I could tell it was getting weak this past winter as it was cranking slower on the colder mornings (not so cold in northern VA this past winter). Then I noticed that it was starting to crank slower again lately as it has gotten warmer. I think the high heat these last few days (98F) finally did it in. Other Tundra owners here at my office (there are several) all have their original OEM batteries or have just recently replaced them after 5 or more years of service. The longest was 7 years.
Of the GM cars I have had, I've never had the AC Delco batteries last more than 4 years.
My typical replacement preference has been Interstate, but this time I told my son to stop by the dealership and pickup another "Toyota" battery, the cost is about the same. BTW the current OEM in my truck is made by Exide (stamped on the top label), who also makes the Optima batteries. (see link:
