Dead battery and oil life question

[cdmintmi]

i can save you all a bunch of headache and belly aching. You bought a Hummer right? So get your ass in it and go wheeling. It looks good in the driveway but it looks a thousand times better out playing in the dirt, mud, and rocks. Get the things dirty and have some fun. I have 45,000 miles on my H3, a power converter for charging cordless tools at work, a detachable XM radio, TomTom GPS, phone charger, and 17.5 mil cp spot light charger in mine on the original battery and no problems. Ive gone camping and listened the XM radio all night and still cranked in the morning. Listen to your dealers, drive em, get em dirty, its what they were made for!!!
