Information

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
