no one will know since that sears link is to the main page (they set up links per user per session).

a model # may help though....



anyway the reason why optima cost more is they are gel cel, not standard lead acid batteries. they are a lot more durable than a standard lead acid battery plus they are safer as far as spilling acid, and so on...my feeling is unless you need the features that an optima has you are wastin gyour money.
the die hard with the kill switch sounds interesting i wish i could find any info on it...how much are they anyway?
