You need to replace the entire positive cable with an OEM one. Nissan is extremely fussy with maintaining proper electrical characteristics throughout their electrical system. Most non-OEM Nissan electrical components fail in this aspect, causing issues.
If you had that much corrosion on the positive cable, then it's more than likely that the negative cable might also be compromised with corrosion.
Replace both battery cables with OEM cables before wasting any more money. This will greatly eliminate one of the main issues with the charging system.
Battery voltage, on a good charger, fully disconnected from the car, should be at least 13.5v, with 13.8v being normal. If it can't get up to this level, it needs to be replaced.
Last, after replacing the cables, and replacing the battery if needed, check the voltage at the battery when you first start the car. Voltage with a properly operating alternator should be between 14.3 - 14.8 volts output for proper charging. Bad battery cables can affect these readings, the reason for changing the cables first.
If the alternator can't maintain this output, then that will need to be replaced. Again, pay for an OEM alternator. Rebuilds have a dismal failure rate. Do a search here for the issues involved with installing the cheaper rebuilds.
You can find OEM electrical items cheaper by shopping the different online Nissan dealers. All the Nissan dealers set their own online pricing, some online dealers offering up to 50% off their list price.
Verify that you're ordering the proper parts by entering your VIN number on the Nissan parts web sites. Once you have verified Nissan's part numbers, you can than do a web search for cheaper pricing. This might work for the cables, but not so much when shopping for the alternator. Be extremely leery of any cheaper alternators, most likely they are mismarked rebuilds or aftermarket knock-offs.
Good luck.
Looking forward to seeing your resolution.
Have a good day.
