Sam's Club also sells truck batteries at a good price.
They may be expensive, but the Freightliner (Alliance branded) AGM batteries are made by Deka/East Penn. Not to many batteries on the market better than theirs. Turtle can chime in with the real reasons but ya get what ya pay for!
About ten years ago,.......,I was told to stay away from Alliance batteries as they were an inferior battery. This came from a Freightliner dealer and a Fleet Pride parts center. After I changed to another brand of battery my battery problems went away.
NAPA sells 925cca batteries that come with a 18 month exchange warranty and 18 more
months pro-rated warranty...36 month warranty for truck batteries is hard to beat.
I paid around $85 for the ones I bought a couple years back and when there was a problem
they replaced the faulty battery/batteries no problem and with NAPA being coast to coast
it was always easy to find an outlet.
I have not tried them. The problem is you need to different types of batteries on a truck. Starting batteries for starting and deep cycle for the sleeper. Generally speaking that is. Some AGM's can do double duty. Charging is always a problem as well. I like to re-condition my batteries often.
So your saying ya running two batery boxes?
I am only running the one set of factory batterys for both the truck and sleeper
I thought of going this way,,but now ya got two sets of batterys to maintaine along with added weight..It propley is the best way to go I guess..I just lke the idea of having one starter battery...
