The batteries on my 2003 Ram were 7 years old when I changed them. We were going on a big trip and figured that was a worthy investment. The batteries in my 2012 were still going strong when I switched to my 2014. The 2014 is a Longhorn and has just about every option you could have in that year. Well in 2016 batteries went bad. Found out this is not uncommon as many of those computer operated items are always draining power. Went to Wally World an got 2 new ones. I live in a warm climate and travel in warm climates. Batteries can be a **** shoot.
