FAQ: Supercapacitor Selection

Q: How do supercapacitors differ from regular batteries? A: They offer faster charge/discharge but lower energy density – think sprinter vs marathon runner.

Q: What''s the main failure mode in capacitors? A: Electrolyte evaporation accounts for 62% of field failures (IEEE 2022 report).

Q: Can I replace batteries entirely with supercapacitors? A: In short-duration/high-power applications – yes. For sustained energy needs, hybrid systems work best.
