JRP...Funny...I had looked at the Odysseys compared to wet cells in price and said "holy xxxx" those are expensive" ...compared to the Lifelines though they aren't bad. If they do what they say...that should put a lot of price pressure on Lifeline, Rolls, Optima etc. etc.
I don't think there is much advantage for a starter...but house batteries with that price differential would be quite attractive given the many benefits over standard AGM/Gels that are touted.

Thanks for that price list, Cam. I somehow missed it on their site.
$192 + shipping for the Odyssey. Since the BD price on the Lifeline includes shipping, the Odyssey will probably come out about $35-40 over the Lifeline. Another factor is that it weighs about 6 lbs more. Not a big deal, but I'm going to be dangling upside down to install this thing, so every bit matters....

JRP...the Odyssey 1200's are NOT much more than the Lifelines.

Thanks again everybody -- very helpful.
Cam, I am inclined to try that Lifeline GPL 1400T that Paul linked to. It prices out at $180 (BD Batteries - delivered) which is steep for a battery of this size (I paid about that price for our Grp 31s albeit 5 years ago -- looks like prices have gone way up). But given their track record on our boat, I know Lifelines represent good value.
I had toyed with the idea of doing some R&D with an Odyssey battery like the PC1200 ( PC 1200 Deepcycle Odyssey Battery, Marine Heavy Duty Battery, Diesel, Trolling Motors - Odyssey Drycell Batteries ), but I haven't found a price for them yet. I expect it will be pricier than the Lifeline, and I really need to cap out the costs of this project....

Gryz...the batteries we are discussing ARE 12V batteries...just different sizes and cranking power.
JRP... that Lifeline looks pretty good to me. The MCA of 550 (MCA=CCA @ 0 degrees F) ...is pretty close to the Group 24 and if you have no problems with the 24 then I'd say it is worth a shot if you can fit it.
I would NOT worry about your charging capacity from the alternator at all. Starting will take 90 amps for 15 seconds or so...which means less than ONE amp hour to be replaced. Even a whole minute of starting is only 1.5 amp hours! About the same as running a cabin light for an hour!!

I guess I am very different. I use a 12 Volt Battery. Guess that Scary today for me, when mine getting weak at 9 years old and out of warranty!
There are $50 batteries out there that last 9 years for the money???? With proper care.
I interested now! Very good question.
Damn, woman says I should add something. I not know, maybe buy a sailboat???? But, I not use much of a battery on a sailboat????
I have had motorboats? but, that different!

There are some smaller batteries than the 24 that are as powerfull. Most of the new cars have smaller batteries as will as 100+ altinators.
Groups 56 and 72 come to mind.
