Battery Charging
IMPORTANT!
Always
connect the battery charger directly to the bat-
tery positive (+) and negative (-) terminals.
For charge voltages and charging times, refer to the
battery manufacturer instructions.
When a battery charger is used in a 12 V system bat-
tery voltage increases to around 13.8–14.4 V. Charg-
ing at high speed with high gas generation may result
in the following:
•
Battery service life is reduced
•
Capacity is reduced
•
There is a risk of shorting in the battery
•
There is an explosion risk
The following parameters govern charging time dura-
tion:
•
How discharged the battery was at commencement
of charging
•
Charger capacity (how much current a charger is
able to supply)
•
Battery size (capacity in Ah)
•
Battery temperature. A longer charging time is
required when a battery is cold. A battery is not able
to receive a high charge current at low tempera-
tures.
It is better to charge at 10 A for 5 hours than at 50 A
for 1 hour, even though the total charge is 50 Ah in both
cases. The battery may have difficulty in accepting a
high charge current.
WARNING!
Explosion hazard. Batteries contain and give off an
explosive
gas which is highly flammable and explosive.
A short circuit, open flame or spark could cause a vio-
lent explosion. Ventilate well.
IMPORTANT!
Never switch off power to the battery charger before
the connections are removed.
