Datasheet

There is no need to limit the inrush current to the battery
during constant voltage charging. The low internal
resistance of EnerSys
®
CYCLON
®
battery Single Cells and
Monoblocs allows for large inrush current without damage.
Since not all of the charge returned is accepted to replenish
the electro-chemical potential, a good rule of thumb to use
is that the charge returned should be 105% to 110% of the
capacity delivered on the previous discharge.
Most current waveforms are not pure DC nor are they pure
sine waves. Therefore, consult the EnerSys Application
Support Department for assistance when evaluating the
charger current waveforms for your specific application.
A three-step 6-8 hour charge profile optimised for CYCLON
cells and batteries is available on request from the Technical
Support Department of EnerSys.
