Keeping your pickles soaked in the pickling solution will help them not spoil, it doesn’t even matter if they were already opened, just make sure they are submerged in the solution. Pickles have been reported to last for more than 3 months past the best-by date.

When homemade, the shelf life diminishes a little bit as they can last for two months under refrigeration conditions.
