I found some posts on this, but none seemed to answer my specific issue. I have a severely corroded battery terminal and acquired a replacement terminal and fuse block from the dealership. The problem is the existing battery terminal on the cable seems to have the post that attaches to the fuse box weld nutted on. I can't seem to find a way to get the post/stud off the severely corroded terminal. Here's a picture of the old/new side by side.
It's a 2008 Frontier Crew Cab 4.0L V6.
These posts weren't so helpful for my specific problem:
The new terminal for the cable doesn't appear to have a crimp on interface and if I could just get the stud out of the existing terminal, I'd be good to go. I thought I had cleaned the corrosion off sufficiently and the rest of the stuff came apart once it was clean enough. I really don't want to have to drill this stud out if I don't have to and I'd prefer not to have to cut the existing terminal off and recrimp a new one on, especially since the replacement part from the dealer doesn't appear to be designed for that. Any help is greatly appreciated.
looks like you may have to cut or drill it .maybe flip over the old terminal and post a pic,try some pliers and twist gently should come off.in the future get some protectection on there

I went to Autozone today and bought a pair of brass marine battery terminals for $4.99. They are made by Lynx and the item # is 01254. The wing nut and bolt can be removed. I plan to cut the 08 battery terminal off after the stud and use that stud as the mounting point to the marine terminal.
^^^ just buy what he did and your set. Take a good look at the terminal. There is a 10mm (i belive) attaching the terminal to that fuse block piece. Unbolt and replace the piece. I got mine at a local auto parts place so you shouldnt have a hard time locatingg one. The replacement ones you can buy are 1000x better than the tinfoil factory one. On a side note, I belive the factory one become streched over time and moves quite a bit on the post itself causing it to ge all that nasty white buildup around the terminal. Once I replaced mine I have not seen this problem and its been a year plus. Hope this helps.
Went to Advanced Auto and got one for $7.99 gold plated. After 2 months of occasionally going under the hood to move the terminal around till the truck started. lol
I am trying to replace the positive terminal for my 2006 Nissan Frontier battery, but I cannot get the bolt off that connects the terminal to the fuse box. How did you remove the bolt?
I did similar on my daughter's '98 Pathfinder positive terminal. Since the marine terminals had a 5/16 inch stud and the Nissan ring connectors had a 6mm hole, and I didn't think there was enough metal to drill, I decided instead to buy a traditional brass repair terminal, and drill and tap it for a 6.0 x 1.0mm stud, and used that.
My positive terminal snapped off last night, so I went to the local marina and got a battery terminal kit from Evinrude/Johnson part # 385407. Had to dill out the trucks connections to fit the 3/8" bolt, but it worked out perfectly.
Be sure to neutralize the battery acid on the batt & fuseblock pronto. Bit of baking soda and warm water, apply with a small brush. liberally. rinse&repeat. then rinse&dry. Apply some dielectric grease to all the electrical points/contacts around the battery to prevent future issues.
Look at your cables and see if you have any corrosion in/on the exposed braids of the cables. If you see any corrosion, put that on your list (new cables) to replace soon.
I replaced the terminals on my sister's 05 Altima, my father's 07 Maxima, my 03 Altima, and my 08 Frontier. My sisters was the worst and I had to replaced both terminals with generic auto parts store terminals. What a pain it was due to lack of maintenance and neglect. I used the OE terminal on the others.
I wanted to add, if you want to connect more wires to the battery, don't tap off the fuses that are already there. My truck has a few extra circuits that connect directly to the positive terminal; snow plow, amplifier, and power inverter.
I modded a stock terminal with a longer bolt to sandwich all of my new power cables under the original fuse block. After all the cables were installed I cut the excess off. On the negative side I enlarged the bolt hole and installed an extender.
looks like I will be doing this... as my battery started to leak around the positive terminal and I have corrosion everywhere... I have blue crusty stuff here and there, and the fuse block might be affected. I might have to drill out the bolt on the cable where the fuse block thing is. Should I get a new positive wire assembly? or a little baking soda water/vinegar neutralize the corrosion? It is an 2005 Frontier by the way.
Some wheel bearing grease or vaseline on the positive terminal - after making your connection - will exclude oxygen from the air and prevent corrosion. And will make your next battery change easier.
I had my positive connector rot through and used one of the marine terminals. I had to swap a hex nut for the wing nut, as there isn't enough room in the fuse block for the wing nut to seat correctly. It might work on the bottom but then it would be a pain to get at. I bought something a few blocks from home. When I tried to restart, got just clicks. Tried again and somehow it started. Checked under the hood and saw lots of corrosion. Cleaned it up with baking soda and took it apart, and found that the part of the connector that goes around the terminal was corroded through and could not be properly tightened. I live in Central City, Colorado. Fortunately, the casinos just opened this week, so the buses were running into Denver area. I took a bus into Lakewood, and it stops at a light rail terminal. Took the light rail one stop to terminal that is a couple blocks from an auto parts store. Fortunately, they had the marine connectors. There is a Nissan dealer in the area, but it would have been another bus ride, and I really think the marine connector will last longer than the OEM one anyway. The only slightly undesirable part is that I now have two half inch nuts on the battery connector, AFIK, the only non-metric fasteners in the vehicle.
