Where the Zodiac kit really shines though is the ability to just "plug n play" because there isn't any custom work involved with the tray and isolator. Everything fits in the stock location and comes with everything needed for installation.They made it easy with the Kodiak kit and kudos to them for thinking outside the box!The 1200 amps is NOT CCA, it's a marketing gimmick number and useless when comparing batteries. Here is the specs for both the Optima yellow top D34/78 and the Odyssey PC1200 (taken from each manufactures technical specs.)
Optima/Odyssey
CCA 750/550
CA 870/725
Res. Capacity 55/44
Reserve min. 120/78
Weight 43.5/38
Volume cu. in. 537/381
The Optima Red top has even better starting specs but for dual battery systems the Yellow top makes more sense.
As to reliability and size, I've had an Optima sitting in the garage that after almost 2yrs still had almost 12V and when installed, started the car like brand new. Of course the Odyssey is small, it doesn't have the power of the Optima.
In short, using Optima yellow tops I can have a better (more power, just as reliable) dual battery system at nearly half the cost of the Kodiak which is charging you extra for nothing.
Give me a Optima any day over Odyssey and their gimmick numbers .
Can you make your own tray and brackets to re locate stuff? Most can't!
Yes, it would take 3 Odyssey pc1200's to equal two Optima 34's, which fit our truck, in CCA and RC.Those are the main 2 specs batteries go by.
While all this is true ,the reported quality of the Optima batteries has gone down hill since Johnson Controls bought them in 2000 and moved the manufacturing from Denver to Mexico shortly after. Although,alot of those that I read are with red tops that people are deep cycling or letting the charge go way down which will kill a starting battery. I have used Optima's for 20+ years with no problems.
Odyssey's reputation on the other hand is the best in the business for reliability and is still made in the USA ,and the high price reflects that. I can get brand new Optima 34's here locally for $100 where the Odyssey's in size 34 or 35 cost $250.
Probably the best buy for the money is a Sears Diehard Platinum Marine which is made by Odyssey for Sears and is right around $200 and even cheaper when they go on sale.Same exact specs in the matching size Odyssey puts out. Same battery insides ,different color.
Putting one on the other side took alot of custom work with fabbing the tray and the reservoir re-location bracket ,not to mention the extra wiring involved.The isolator I recently switched to is a 200amp Cole Hersee "Smart Isolator" for it's automatic operation and reported superior quality by friends who work big rigs.It's what they use. http://www.colehersee.com/pdf/hot_feed/D-617_SmartBatteryIso.pdf
