An awkward subject title I know but I couldn't fit exactly what I wanted within the letter limit. I guess I'm excessively loquacious in my verbiage.
I've got a 2008 Cadillac Escalade ESV I bought used in 2011. The AC Delco battery died within 2 months of my ownership. That should have been a sign, but I replaced it with a new AC Delco from a GM dealer. It lasted about 2.5 years and was replaced on warranty. It just died again, warranty expired. I bought an aftermarket labeled battery from a local battery distributor. 3 batteries in less than 6 years of ownership? Grrrrrrr. The vehicle is completely stock. I don't listen to music or watch DVD's with the key off. I only put about 10,000 km a year on it. The battery does seem a bit small for a 6.2L LS3 engine.
I found a few threads on Cadillac forums about guys adding a second battery to solve this problem. Chevy Tahoe's in police spec come with two batteries from the factory. Evidently, GM parts are available to install a second battery, and the second battery tray is already present, so it sounds not too difficult.
Has anyone done this?
