So what is WEC long life snap in E-cap applications?
In most applications, aluminum electrolytic capacitors – as poled devices – are used with a DC voltage bias of proper polarity with some superimposed AC voltage.

Meanwhile, how to distinguish general purpose grade and long life grade capacitors?
Aluminum electrolytic capacitors are generally divided into two basic reliability categories: capacitors for high-reliability applications and capacitors for general-purpose applications.
This differentiation has also been adopted in the relevant IEC standards.
In IEC publications aluminum electrolytic capacitors for high-reliability applications are identified as "Long-Life Grade" capacitors. The abbreviation( LL )is stamped on the capacitors.
Aluminum electrolytic capacitors for general applications are called "General-Purpose Grade" (GP) in IEC publications.
