There is no need to limit the inrush current to the battery

during the initial phase of constant voltage charging.

The low internal resistance of GENESIS batteries 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.
