I then moved to a higher priced wet sealed battery and same deal, lasted 2 yrs on maintenance charge as a cranker, so I went the Optima Blue unit because its he same capacity as the yellow but has the extra terminals for aux. cables. I spoke with the guy at Battery world and he confirmed its a casing change to define industry use, but same internals. There is no extra anti vibration 'stuff' inside it regards pounding from marine use according to him - unlike the wet cells that do have some differences in the baffling I understand.
I cannot attest to whether there is any improvement as yet, yes its an expensive battery but if it has lower self discharge and retains high CCA capacity then I am going to be happy. I selected the 8027-227, 845cca and this is ample for the Chev even when sitting for 3 days below zero, kicks off strong.
