Need new battery for U.S. 77 308GTB

I’ve always been happy with the Interstate battery, my last Interstate battery lasted 11 years.

 

I’ve had a Duralast Gold in mine for two or three years now. I do have a CTEK harness connected to it. If the car is going to sit for a while, I plug it in. It’s been holding up well.
In the other cars, I’ve had very good luck with the Duracell batteries from the Batteries+Bulbs store. Good warranty as well.

I use an Interstate, nothing special. Has done well for the past year since i bought it. I don't even bother with unplugging the terminals; it can sit for 2-4 weeks before starting anew, no issues.

 

You're thinking about this far more than I did. I pulled my old battery out, drove to the Interstate store, put it on the counter and said "I need a new battery. This is the old one. I need same/similar including dimensions." The guy pulled out a measuring tape, noted the terminal directions, and walked to the back room, came back with a flooded battery and said "This should do fine."

 

Just pick up a BCI group 34R (which will tell them the size and the location of the positive/negative posts), and 440 cold cranking amps is fine.

Just a standard lead acid battery is ok, you don’t need anything fancy in a 308. [emoji6]

Height is an important dimension. If its too high the cover won't fit properly.

 

Very true. Thus my mention of the tape measure.
