HVC 4F - Important General Notes to Discharge
� Typical discharge performance data can be only reached with fully charged HVC Powercaps,
e.g. charged before with standard charge conditions (constant current (CC) – constant voltage
(CV) 30 min at Room Temperature (RT).
� Typical cut off voltage per cell at discharge is: 0.8 V
� For special applications a lower cut off voltage is feasible (e.g. for low temperatures and/or
high discharge currents). Please contact VARTA.
� Storage in deep discharge conditions has to be avoided, e.g. drain by an ohmic load. See also
our HVC Storage & Self-Discharge Information.
� Max. leakage current continuously: < 5 – 15 µA
Leakage currents by application (circuit board, etc.) need to be avoided or as low as possible
(e.g. by a controlled switch, a MOS-FET, etc.).
