If charging 8 lights (or 7 1 MLC) fully exhausted uni
ts from a vehicle’s 12V supply the total load
will be 4 Amps. The cable and connector (with 5 Amp fuse fitted) are capable of supporting this load.
Be aware that many vehicle supply sockets may be unable to support this load or that the vehic
le’s
socket (and then the cable connector) may get hot.
This could present a fire hazard.
This is particularly
likely with an old, used socket. If in doubt, reduce the number of lights being charged simultaneously.
Also be aware that this load will reduce the charge available from the vehicle battery.
Battery Status LEDs:
When power is first applied to the MLC, the internal charging
circuit first determines the state of the battery, only going to full
charge if the battery passes the initial test. If there is a problem
with the battery the red Fault LED will be lit. See later section on
action to take.
The charger is an intelligent dual-rate charger and, after the
initial battery check, will determine exactly how long to charge the battery and at what rate. It will
switch off automatically at the end of the main charge. During the initial high charge rate the
Charging LED will be lit. This will extinguish once the battery is fully charged.
After Charging:
Once fully charged (and with the charger still connected and switched on) all LEDs will be off.
At this point turn off the charger.
Li-Ion batteries have a very low self-discharge current and neither need nor benefit from trickle
charging.
A refresh cycle should be performed once every 6 month (more frequently in very hot conditions
– see table below) to maintain full charge and best battery condition and life.

Disconnection:
To disconnect the charger, switch off the mains supply and remove the power cord or disconnect
the DC power cable
Re-store the cable
Good Practice:
Never charge batteries from the mains power supply with the case lid shut
There is no need to leave the charger connected
Always isolate from the mains before connecting/disconnecting
Only charge batteries indoors in dry conditions
Keep batteries away from sources of heat and direct sunlight
Routinely recycle as outlined above
Never charge a battery that appears damaged
Never use a power cord that is damaged in any way
If in doubt
– have it checked out
