It's a monster and I can't wait to test it out with the furnace!

I was looking at that DIEHARD PLATINUM Group 31 Battery too as an alternative to the Lifeline. It specs out about the same weight/performance-wise and has a three year warranty, plus is about 50 to 75 dollars cheaper each. Two of them will fit in my battery compartment easily and they do measure a little larger than the Lifelines. I'd like to know if it's Chinese or not?
Got any knowlege you've gained about them you'd like to share with the rest of us?
I read this on the SEARS website from the link you provided. It says the PM1 DIEHARD PLATINUM is made for SEARS by ODYSSEY.
purchased a PM-1 in May, 2011 to replace an Odyssey PC2150 for dry camping in our RV. The PM-1 is a high quality Absorbed Glass Mat (AGM) battery manufactured by Odyssey for Sears. The PM-1 is similar but not identical to the Odyssey PC2150. The PM-1 weighs 75 lbs while the PC2150 weighs about 78 lbs. Brand new the Odyssey measured 73 AH @ 13.02 VDC (with my Gold IBT intelligent battery tester) and the Diehard PM-1 only 34 AH @ 12.86 VDC. For my purposes the PM1 is plenty but only time will tell about durability. AGM has the advantages of being impact and vibration resistant with a very low self-discharge rate. I highly recommend a charger designed for AGM batteries like the DieHard Platinum Microprocessor-controlled Battery Charger ($90) or one of the high quality recommended chargers on the Odyssey website that cost more (e.g. ProNautic 1250, Odyssey OMAX-40AS-3B, Pro Charging Systems PS3, Charles 93-12405SP-A, etc.) A regular automotive type charger with 15 to 16VDC output will overcharge and destroy an AGM battery. One designed for AGM has an algorithm that limits the bulk/absorption charge to 14.8V with the trickle charge regulated between 13.5V and 13.8V. Your battery charger needs to be a minimum of 40 amps to properly refresh the PM-1. I believe using the 30A power converter in my RV was one reason my PC2150 didn't make it 4 years. See the three step charge profile under "Chargers" at odysseybattery.com.
Hope they work out well for you.
