It's come that time to change out my chassis batteries. I have an '05 Thunder with a Cat 525 engine. My present batteries say Interstate 31-MHD and a CCA of 950. I'm assuming the 31MHD is the series? I was looking at Interstates from Cosco today and the heaviest CCA they have is 850.Question ? Do I need the series 31 and/or the 950 CCA? Or can the Costco 850s suffice?

Neil,
I wouldn't go with anything smaller than the 31 series and the 950 CCA. A lighter battery might work now but if it gets cold and slightly discharged... You'll also probably end up replacing them sooner.

Neil,
About 2 years ago I attempted a start and it was sluggish. I pushed the jumper button and got started. The mission for the day was a refer recall. While I was at Sumner RV getting the recall, I got a quote for Interstate chassis batteries. I was impressed but not the right way. I got on the phone and found Budget Batteries on Old 99 in Milton. (7900 Pacific Hwy E Milton Wa 98354 http://www.budgetbattery.com/locations1.php
It's big, for a battery place. They have everything from fork lift to golf cart batteries. They have all sizes and shapes. The price was good and they were a match for what what I had. I bought them and they installed them for me in their lot.
Here is the weird part. There was no label on the batteries. I asked about having the warranty date on them. The manager opened a file drawer, pulled out some labels, punched the date codes and stuck them on. Always curious, I asked why the labels weren't on them BEFORE they went into my motorhome. He said it was because they never knew who might be selling them. He said that as a "wholesaler" other battery brands might be applied. As I was leaving, a van with "Interstate" written on the side pulled in to load up with batteries! The Interstate guy had his own labels.
I think they have a branch in Bremerton if you don't want to pay the bridge toll.
