Battery in my 08 durango finally bit the dust this year ,won't hold a charge. What do most of you use as a replacement brand? Thanks for any reples,John

I have had good luck with Interstate (so far)

Interstate worked OK for us. When it died, we replaced it with a Sears DieHard group 31 as we didn't have room for two batteries in the rig we had at the time and were going to spend time at Yellowstone in a campground with no electric. Worked well for us. If you do plan to stay at non-electric sites, you might want to consider two batteries, either 12 volt in parallel or 6 volt in series. Or, if like us with no room for a second battery, look for the largest capacity 12 volt you can find.

I usually go with Diehards. They seem to last about 5 years.

I just took my old one to NAPA and told them I wanted at least an equivalent. Still works fine after 3 years.

There are very few battery manufacturers. They make all the different labels on a contract basis. Buy whatever you get the best deal on. It will most likely be made at the same place as the one down the street with a different name on the side.B.O.

Thanks, Miatared. I was just curious what they were normally running. I recently purchased two but am too embarrassed to say how much I paid. :o

No need to worry if you don't dry camp. Interstate car batteries have always been really good but I don't know anything about their RV batteries. I use a bipap and we dry camp a lot and always used 2 - 6v. FWIW, I can go 3 nights on T105s and NAPA Specialty but not on Costcos. I added solar so the Costcos are fine now. Craig

John -

Here's a good rule of thumb to use when replacing batteries. I fusing 6V bats, you add the voltage by putting them in series but only get the ampere hours of one battery (can't add amps in other words). So two 6V 450 ApH gives 12v at 450 amps. If you want 12v but want more amps (think leaving the lights on longer, running more lights, etc.) then use two 12v in parallel. Then using two 12v at 450ApH would give you 12V at 900 amps. The reserve amps is what you want to check not so much cranking amps. Also you want to use a deep cycle or marine style battery because of the type of cycling on the battery. You can choose what battery and price you want, you determine the price break based on amp hours and type of battery.

I got 2 Interstate 6 volt golf cart batteries from Costco for $90 each including battery fees as I had no core trade. So far, so good. My coach also came standard with a 3 stage charger which is important to longer battery life. Phillip

When we bought our trailer 11 years ago and I installed 2 Optima Blue Tops and they are still going strong.
