between charger terminals and battery termi-
nals. Note! Make sure the charger terminals
are not short-circuited and ensure that the
polarity is correct.
• If the charger is equipped with battery clips; first
connect the positive clip (RED) to the positive
battery pole, then connect the other clip (BLACK)
to the battery’s negative pole.
• To charge batteries in vehicles; first connect
the positive clip (RED) to the positive battery
pole (The one not connected to the vehicles
chassis), then connect the other clip (BLACK) to
the vehicle’s chassis - a good distance from the
battery and fuel system (fuel hoses, fuel pump
etc.).
• The charge cycle starts when the charger is
connected to the mains.
• If the charger is disconnected from the mains
voltage during a charge cycle the charger will
start a new charge cycle when it is reconnected
to the mains.
• When charging is complete, disconnect the
charger from the mains before removing battery
connections.
If the charger is equipped with battery clips:
first disconnect the clip from the battery’s posi-
tive pole then the other from the negative battery
pole/vehicle chassis, in this order.
• The recommended minimum battery capacity
for which the specific charger can be used vary
from battery to battery. Some do not have a
capacity restriction at the specified boost voltage
level while others have restrictions. Please
follow the datasheet and recommendations from
the battery manufacturer. In our tables we use
typical C/5 as a maximum charge current for
Lead Acid cells. C/5 means that charge current
for a 10Ah battery should be max 2A. Thus the
typical minimum capacity recommendation is
then 10Ah for a 2A charger. For max battery
capacity we have used 50 times charge current
for chargers with timer (and/or uC) and 50 times
current detection levels for chargers using only
this termination method. For a 2A charger with
0.25A current detection level the max capacity
recommended will be 50 x 0.25A = 12.5Ah.
Again this is just typical recommendations.
Please read recommendations and datasheets
from battery manufacturer.
