Charging A Battery That Is Installed In A Vehicle
WARNING:
Marine (boat) batteries should be removed and charged on
shore.
To charge it on board requires equipment specially designed for marine use.
Position all cables in a manner that will reduce the risk of damage by the vehicle's bonnet,
door, or moving engine parts. Stay clear of fan blades, belts, pulleys, and other parts that
can cause injury to persons.
Check the polarity of the battery terminals. POSITIVE (POS, P, +) battery terminal usually
has larger diameter than the NEGATIVE (NEG, N, –) terminal.
Determine which battery terminal is grounded (i.e connected to the vehicle chassis.) If the
negative terminal is grounded to the chassis (as in most vehicles), refer to
Figure 3
. If the
positive terminal is grounded to the chassis, refer
Figure 4.
for connection.
For a negatively grounded vehicle, connect the Positive (Red) clamp from the battery
charger to the Positive (POS, P,+) ungrounded terminal on the battery.
Sealed Batteries
Charge sealed batteries on a slow charge rate, carefully monitoring the voltage across the
battery terminals using a normal tester. When the battery terminal voltage reaches 14.4V
for 12V batteries or 28.8V for 24V batteries, stop charging.
Multiple Battery Charging
A number of batteries may be charged at the same time using a parallel connection as
shown in
Figure 5
. Two batteries may be charged in series using the 24V output as shown.
Fuses
The charger is equipped with 2x
50A
front panel mounted fuses (
A
) as shown in
Figure 6
.
The fuse will interrupt the circuit in the following circumstances:
a)
Overload - when excessive current is delivered to the battery.
b)
Short circuit - clamps touch, or cross-connection to battery.
If the output fuse blows you can take the following action to replace it immediately:
1.
Disconnect the charger from the mains power supply.
2.
Allow the unit to cool down and establish the reason for fuse blowing and correct the
problem.
3.
Replace the fuse. Do not use a fuse with copper bridge or similar as these will damage
your starter charger. Refer to the specifications for your charger to determine the type of
fuse you require. We recommend that you hold 2 spare fuses with the charger.
Thermal Protection
•
When a high current causes the charger to overheat the internal thermal protection will cut off the current.
•
When the charger has cooled sufficiently it will automatically reconnect.
Please Note:
Any equipment damage caused by the use of an incorrect fuse will invalidate the warranty.
