Lifeline vs Interstate 8D AGM coach batteries

I have Lifeline 4D Coach Batteries in my Coach (2005 40' DP) that are the originals and are 11 years old. They are due for replacement! I have room for 8Ds and was thinking of replacing them with 8Ds (I can handle the extra weight). My dealer has a good deal with the local Interstate Battery people who make a similar battery (I am told). I have used Interstate Batteries in my cars and been happy with them. Does anyone have any relative quality comments regarding these two batteries? Are Lifelines better? 11 years is pretty impressive but the Interstates are about $200 cheaper. (Total). If they are comparable then I am happy to save the $200, if not the $200 (especially over 11 years) is not a big concern.

Lifelines would be the standard that others are judged by. If you are looking at Interstate don't forget they are made by Johnson Controls who make the majority of the various so called brand names. So if it is money you want to save you could even use one of the other alternatives from JC and save even more. Else use one of the best with Lifeline.

I'd go with the LifeLines if you can swing the extra $$ although the Interstate U-2200's in our last rig went 10 years and they were flooded cell.

I replaced my lifelines with same. I see guys getting 10 plus years out of some. I don't believe you could get that kind of potential longevity out of the other brands. Also you can get the copper blade battery post which make a clean contact.

As Poppasmurf says, Interstate is not a battery manufacturer, but that is true of many of the brands you see advertised or on the shelf. There are basically only 3 big battery manufacturers in the USA (Johnson Controls, Exide, and East Penn Manufacturing), plus a few smaller specialty makers such as Trojan, Concorde/Lifeline, and US Battery.

Interstate buys from both US Battery (their 6v GC2 batteries) and Johnson Controls, and perhaps select models from the others as well. That doesn't make them good or bad, though.

I'm a fan of Lifeline batteries, but if both brands are AGM, I see no reason not to save the $200 with the Interstate deal.

I too like the Lifeline. If not going with them, just get the Costco/Sams AGM 8D, as they would probably be less then the Interstates. Also might check into Full River line, as they're getting good press in both RV'ing and Boating forums, as a lower cost alternative then the Lifeline's.

You might also check to see if L16's will fit for your application. We replaced two 8D's Deka's with four Lifeline L16's. (Taller battery, so headroom is usually the limiting factor here.) On year 3 now, and performing well.

Another fine battery you may want to research is the Rolls Surette model S12-290 AGM. It is an 8D 290 AH with a 2 year free replacement and 5 year pro-rated warranty. Rated at 260 AH @ 20 hr. rate.

Thanks for all the great answers. I will do a bit more research. The $200 isn't a big deal in the scheme of things, just thought there was no reason to spend it if they were equivalent!
