Generally in AC we consider voltage, frequency and phase
sequence for parallel operation ... Can we parallel two DC
battery chargers? If yes, then what precaution to be taken
when we parallel two DC power?

Answer Posted / omkar

) The voltage of both the chargers should be the same.
2) Both chargers should be connected in the same
polarity.
3) The output impedance of both the chargers should be
the same, so that both deliver equal current. (It is not
necessary that both the chargers should be of the same
make. It would rather prefer same model than same make.)
4) The characteristics of both the chargers should be the
same. Both should be set at the same current setting for
changeover from boost to float.
5) The current capacity of both the chargers should be
the same.
