I prefer to replace the battery B4 it leaves me stranded in the middle of nowhere,how ever if you enjoy being stranded with a dead battery that's up to you . I never trust a battery that is more than 3 years old . if you can afford an H2 you shouldn't worry about an $85.00 battery . as for me not being very helpfull that is BS ,I gave him the short sweet answer to his question and thought it would leave no doubt in his mind .
get a group 79 battery at Checker or Costco ,they fit right and willl give you the 880 CCA your truck needs . I tryed Optima's and they Do NOT have as much power . if you are realy hard core and are willing to work you can put 2 batterys in your truck .
