I went to the auto store just this morning, actually, and traded in my oozing John Deere "Strongbox Hibernator," for a comparable size Autocraft Silver 272. It was $69, and with the $10 credit on trade-in, came to $73 with tax. There were two different Optima's on the shelf, and to be honest I was confused by their sizing, and not sure which would have been the right one to get. I know everyone who's swapped out JD batteries has gone with the Optima, and I was in fact looking at those first. They were about $109, if I remember right.
Are you suggesting that I should not put in the Autocraft Silver, and go with the Optima? If so, could you tell me the right Optima to get for my 990?
