Went out to start my truck this moring and it would just barley crank. I lucked up and it started. Will a group 31 fit in a 2007 with a 5.9 if not what cca do you all recommend. I want to put amg type batteries in it

 

Group 31s are longer in length than the OEM group 65. If you want AGM batteries. I recommend you look at the Diehard Platinum group 65 batteries sold at Sears. They are rebadged Odyssey batteries manufactured in the US by Enersys. I use them in my vehicles and have nothing but good to say about them. I have commented quite a bit on the DTR about them. Search this site for additional information.

 

What about Optima batteries 1000 cca

 

Manufactured in Mexico and have suffered some quality related issues over the past few years.

 

Thanks for the info

 

You can save 50 dollars off the cost of 2 Sears Diehard batteries if you order online using Code SAVE50. Then you can pick them up in the store.

 

Rail Man,

Group 31's fit nicely into the unit with the following mods.

There is no room for the "blankies" but they are not needed on a commercial series battery.

I had to extend the small ground cable (drivers side) to the frame a couple of inches.

I rebuilt the hold-down bracket for the heavier batteries.

 

Put new batteries in today went with the advance auto platinum amg batteries 750 cca spins it over better than when new.

 

They (AAP) offer a 30 percent off discount code when you place an order online for in store pickup.
