The conventional wisdom is that the bad capacitors (the ones with stolen chemical formula) bulged because of the hours you put in it. Today I found that it’s not true.

Reminds me of Duralcell’s Alkaline batteries (never used) that leaked during storage (before the expiration date). Stop blaming the bad chemical formula on how users use them!
