For a good electrolytic in a benign environment this can take a number of decades. For a bad electrolytic or a good one being misused it can take a few years. Routine replacement of capacitors as a ''repair'' or ''upgrade'' technique is silly, unless you know you have a badly designed unit or one with bad caps.

The ESR of a good electrolytic capacitor is almost always < 5 Ohms except for very small uF values (1 uF or less) They may never set foot on the factory floor. Once it''s designed, prototyped and final approval, it goes to production and Purchasing dept bids out the parts. Like I say, this could be in a whole different country.

- Used capacitors that came from a circuit, where the operating voltage was much lower than the rated voltage of the capacitor. Example: 6.3V electrolytic caps that were used on the CPU filter output of a motherboard (where the working voltage is often less than 1/3 to 1/4 of the rated voltage.) Why should electrolytic capacitors be reformed?

Don't ever buy capacitors from China. Especially top brands from the post above. In addition to those there are: Vishay and Kemet are not "premium" grade electrolytic manufacturers. Kemet makes fine poly's and Vishay makes fine ceramic caps. I would not recommend ether as first choice for Electrolytics.
Diamond-like coatings for improved operating fields In conclusion, capacitor manufacturing has seen significant advancements in recent years, with leading brands like Cornell Dubilier, Panasonic, and Murata at the forefront.

Capacitors seem to be one of those things that is counterfeited a lot, so definitely want to buy from good sources like Digikey, Mouser etc. AVoid Ebay, Aliexpress, Amazon etc as you don't know what you're getting. Re: Capacitor brands? Vishay and Kemet are not "premium" grade electrolytic manufacturers.
Electrolytic caps should be stored under specific conditions in order to retain their electrolytes, and especially for use in SMPS units, their storage period cannot exceed a specific threshold. If the recommended storage period is exceeded, the capacitors need to be checked one-by-one (including ESR and capacity measurements).
When it comes to electrolytic caps, since they are hugely affected by increased temperatures caused by heat build-up at the PSU's internals (but mostly by current ripple), the caps made by Japanese manufacturers are the safest and highest-quality choice. This is also why Japanese capacitors are always preferred.
