Recharge time depends on the depth of the preceding
discharge and the output current of the charger. To
determine the approximate recharge time of a fully
discharged battery, divide the battery’s amp. hrs. by
the rated output current of the charger and multiply
the resulting number of hours by a factor of 1.75 to
compensate for the declining output current during the
charge cycle. If the amount of amp. hrs. discharged
from the battery is known, use it instead of the battery’s
capacity to make the calculation.
When charging batteries in series (positive terminal
of one battery is connected to negative of the other) all
batteries in the string will receive the same amount of
charge current, individual battery voltages may vary.
When charging batteries in parallel (positive terminals
are connected with positive terminals, negative terminals
with negative), all batteries in the string are subject to the
same charge voltage, but the charge current each battery
receives can and will vary until equalization is reached.
Notes
SLA Charger Selection Guide
* The “NRTL/C” mark appearing next to the CSA stamp indicates that the charger was also tested to meet U.L. requirements (UL 1310). Under the provisions of this agreement, CSA
and U.L. can now test to each others’ specifications and thus obtain approval for both organizations.
** PSC-122000A and PSC-124000A can be switched to accept 115 VAC or 230 VAC input (47-63 Hz) allowing usage both here and abroad.
*** PSC-124000AP should be used when the automatic dual rate charger is used like a power supply. As such it can supply a continuous load current of up to 2.5A, yet still switch into
float mode (13.8V) when the battery is fully charged.

Power-Sonic does not offer chargers for batteries with capacities higher than 100 AH. If you have any queries or
difficulties in locating a suitable charger for batteries above 100AH, our Technical department will be happy to help.
