The question in not what Nissan paid , it's what you failed to pay attention to.
It's obvious that you neglected to correct the corrosion problem that started some time ago evident by the crystalized blue corrosion shown in the picture.
It's also obvious that the excessive corrosion that was left unchecked caused the posative terminal end to rot away to nothing.
In the pic the area is clean but look closely, the area has been cleaned of corrosion and rinsed with water, the top of the battery is still wet. Show us the befor pic dude, that tells the whole story
This one is on you dude, not Nissan.
Good thing you did not need a new fusable link block , that would have been an additional 40 bucks on top of the posative terminal cost.
Sorry, this is a known problem, and as we speak, Sentras are being recalled for the same issue. I predict the X will be recalled as well. That is the sorriest excuse for a battery terminal I've ever seen in my life. Sure, I suppose I should have removed the plastic cover before the green crystals of death began to creep from under it, but 30+ years of driving, I've never seen a terminal on a car so new go to hell so quickly. That copper strap is about !/2 or less the thicknness of a penny.
I'll be fixing this one myself; the last time my car was in the stealership some mechanic left a loose bolt in the intake. Said loose bolt ended up wedged in intake valve #2. The dealer tried to make me eat a new engine and labor (no joke). Fuck dealears.
You could also pay attention to the increasingly poor quality of components like this on cars before you get on your big white "Master Tech" horse and tell us poor masses what incompetents we are. That battery terminal strap is a piece of shit, period, and probably cost Nissan all of 99 cents. New heavy duty terminal, new fusible link block (you think I"m going to trust this now?) and a condenser system.
