What has been your average duty life on the batteries ????

 

I bought my 2004 on November 7, 2003 and still have the original batteries. No problems yet.

 

'03 with the original batteries.

Same here I still have the original batteries on my 03. Mechanic buddy of mine told me not to long ago I should think about replacing them since their almost five years old. My truck was built in Nov 02.

My old Ford gasser had original battery for 9 years and about 175000 miles. It was fine but the terminals were badly corroded when I went to do an oil change once and I decided to take them off and clean them. Bad move. terminal broke out of battery casing. Nothing like a late Sunday evening trip borrowing someone's vehicle to the auto parts store before they closed to get a battery and come home to install it in the dark so I could get to work the next day

 

not to sound like a smart*** but there is a thread just like this a few pages long if you do a search

Edit: remember seeing it but can't find it for you

 

I've had my original batteries since new.. the truck was built in March of 04.. I think... Still work great, and look new.

I replace a battery once a year or so, on average. The rough roads up hear pound the snot out of them.

 

Got my '04 early Dec. 2003, batterys still seem fine.

 

I am going to replace my batteries on my 2004 next week with 2 deka 70 series batteries.It might just be me but my 2004 seemed to fire right up after a turn of the key,now it cranks a second or two until it fires.coobie
