3.6 Number of cycles
The number of cycles (cycle life performance) is strongly dependent on the loading of the battery
and the conditions (temperature, charging currents and discharge currents) under which it is used. A
partial discharge of the battery reduces the loading and extends its service life, as does a partial charge.
Elevated temperatures and high currents have a negative effect on the cycle life performance.
■
IEP 014-CP: Set to 3.98 V per cell. This guarantees a higher number of cycles. If desired the charge
cut-off voltage can be raised to 4.20 V, which creates a penalty against the achievable number of
cycles.
The following values serve as indications. No more exact conclusion can be reached until the
relevant proles of load, charge and temperature prole can be tested at the battery for the
application in question.
