Using a DC Source to Charge Batteries

12V or 24V systems such as vehicle power outlets and lead acid batteries are
acceptable sources of power for the Charger. Power sources other than
nominal 12V or 24V cannot be used.
The DC supply to be used must be capable of supplying sufficient current to
operate the number of Chargers connected to it. As each Charger can draw
up to 4 Amps (when charging two sets of batteries), a 12V vehicle battery
system requires the DC supply wiring to be capable of supplying 4 amps for
each Charger.
To avoid completely discharging a vehicle's battery, an inbuilt feature of the
Charger will suspend charging if the power source voltage drops below a
preset level. As each Charger can draw substantial amounts of power from a
vehicle's battery, Minelab recommends charging no more than 2 sets of 4
batteries while the vehicle's engine is switched off. Charging more than this
could result in difficulties when starting the engine.
If the Charger has suspended charging due to low input voltage, normal
operation will resume once the voltage has returned to normal (eg. by starting
the vehicle engine). Similarly, if the power source voltage is too high, the
Charger will suspend charging until the voltage returns to normal.
Insert the four-pin plug of the DC Crocodile Clip lead into the four-pin socket
on the rear panel of the Charger (refer Figure 3). Tighten the plug-retaining
nut to prevent the cable becoming loose – finger tight only.
Next, attach the Red clip to the positive (+) terminal of the battery, and the
Black clip to the negative (-) terminal. Ensure each clip is making good
contact by cleaning the battery terminals first. A poor connection could be
caused by dirt or corrosion.
