09 battery upgrade
so my 09 fx4 has had to be jumped 3 times in the last week and i cant stand the thought of putting another tiny 650cca battery in it. is there an option in putting a bigger batteryin it? my dads '11 has a bigger battery in it and seems to have the same battery box. has any of you put a bigger battery in an 09?

My'09 came with the small battery I asked the dealer to change it for the larger one as I do amateur radio work with truck parked .The manual lists both sizes that fit .
Batteries still last not much more than 5 years ,less in the south more in the north. You might check out the whole system while you change batteries.

The 09's came with the group 59 540cca
As long as you stick to a group 65 battery size...theres alot that will work
The better brands are sears diehard platinum, dekka, odyssey.....
FYI.....The 2011's came with an upgraded group 65 battery...

I put in the 650 CCA, 72Ah, Gr 65 battery to replace the Gr 59, 540 CCA, 58Ah battery in my '09. Battery box was designed to fit both Gr 59 & 65's. There is a also a motorcraft Gr 65, 750 CCA, 78ah battery available.
