Battery life

[redsmoke]

When should I change my batteries out. I can't find date stamp on any of the batteries so don't know how old they are. It keeps starting it everyday. Little slow when cold out. Seemed to stay charged all the time guess just wondering when I should change them out to prevent problems to ficm.

If they are Motorcraft batteries, I would guess they are as old as your truck. 4-5 years is pretty good for OE batteries.

Have them load tested if your worried. You change them when their bad, no set time, some batteries last 2 years some 7+. average life is approx 4-5years.

I could not find a date stamp either, my truck is a 2004, which I bought used.
Build date Dec 2003, sold new July 2004.
I load tested them a few months ago...good. Still, they are 6.5-7yrs old.
I may replace soon, just to be on the safe side.

i usually end up changing mine every three years or so, I dont like putting extra wear on the starter or being stuck somewhere with dead batteries. make sure you change both of them at the same time.

Mine tend to last about 3 years per set. Ive gone through two sets since ive owned the truck. I drive my truck everyday for the most part. The longest that I have gone is about 4 days without starting it.

My original batteries were good for 5 yrs.

About 3 years is what I expect. Longer, I'm happy. Shorter, I don't buy that kind again.

Damn, Im still on my original batteries on my 04, they were just checked at the dealer too and they tested good.

I think mine are on the way out. Truck is taking twice as long to start.
