I ended having the local dealer order a new OEM "True Start" battery. So far, it's substantially better than my old one. I don't have any major power needs, but the cold was getting to my old one. It's a 5 year battery, and backed by a free replacement warranty, so that gave me peace of mind!
Two Polar Battery group 27s (one with reverse (+) terminal. Nothing fancy, though I am planning on putting a 3rd deep cycle agm battery in the back connected via a DC-DC+MPPT controller.
Touché!it’s just a re stickered interstate. Same exact one they sell at Costco.
I have been toying with replacing one of my under hood battery's with a capacitor bank, then putting a lithium on a DC-DC in the back.
I looked at the Lithium option, but stopped when I saw the cost. LOL
What model interstate are you running? I also prepare for my first 2 battery set up I prefer interstate batteries from Costco.Optima is crap since they were bought by johnson controls, interstate batt's from costco are the ticket......
I run 2 of the largest deep cycle rv batt's from costco in my 80, they perform great, you have to trim them a bit to get them to fit, and it is a tight fit, but the capacity is great with the two rv deeps...
From the sounds of it @1973Guppie might be running a 31 series battery in his LC, I assume this because he mentioned that the battery box had to be trimmed.What model interstate are you running? I also prepare for my first 2 battery set up I prefer interstate batteries from Costco.
I'll be adding solar and an mppt controller to the mix eventually, I'm tempted to just put in 2 basic lead acid interest Costco 24f
Thanks
I tried returning my Interstate Battery in May of this year...under 4.5 years and listed in the computer as a 5 year warranty...they (costco) wouldn't honor it. I was really surprised.I have a hard time believing that the Costco battery is any less quality than the regular Interstate. Back when Costco sold Kirkland brand Optima batteries I bought them there. Most lasted 5 years or more. The one that didn't make it past year 4, I returned to Costco and they gave me a brand new one, no questions asked. I'd buy the Interstate Costco brand for my toy hauler but they don't have the sizes I need.
They use to give you a battery with out any questions but I believe the only pro-rate the warranty now.I tried returning my Interstate Battery in May of this year...under 4.5 years and listed in the computer as a 5 year warranty...they (costco) wouldn't honor it. I was really surprised.
