SUMMARY

Gold Cap supercapacitors rated at 3.3 Farads and 2.5V exhibit a natural self-discharge characteristic, which is normal behavior. In the discussion, Ramone reports an immediate discharge upon charging, indicating a potential issue with the capacitor or measurement method. Experts suggest verifying the discharge rate to assess if it exceeds typical self-discharge levels, which can vary based on the capacitor's quality and age.

PREREQUISITES
  • Understanding of supercapacitor technology and specifications
  • Knowledge of self-discharge rates in capacitors
  • Experience with voltage measurement techniques
  • Familiarity with Gold Cap supercapacitors and their applications
NEXT STEPS
  • Research the self-discharge rates of Gold Cap supercapacitors
  • Learn about measuring discharge rates accurately using multimeters
  • Investigate potential causes of excessive self-discharge in capacitors
  • Explore best practices for charging and maintaining supercapacitors
USEFUL FOR

Electrical engineers, hobbyists working with energy storage solutions, and anyone involved in the design or maintenance of circuits utilizing supercapacitors.

Dear Experts

I am using Gold Cap super capacitors. About 3.3 Farads ones at 2.5V.

When I charged it to 2.5V, it immediate starts to discharge within a few seconds even when not connected to load.

Is this normal?

Thank you for reading.

Best regards
Ramone
