battery.
Alternator % LED illuminated
When the charger is NOT charging; start the vehicle and turn on the vehicle’s
headlights. The alternator percentage range is from 0% to 100%. Readings below 0%
will read LO, readings above 100% will read HI. If you get a HI or LO reading have the
vehicles electical system checked by a qualified technician.
The below information is a detailed explaination of the 10 stage charging process:
STEP 1: ANALYSING 1 (Checks if battery has connected with the charger)
STEP 2: DESULPHATION (Pulsing charging to remove sulphate)
STEP 3: SOFT START (Charges with gradually increasing charging current)
STEP 4: CONTROLLED CURRENT CHARGE (Adjusts the charging current intelligently)
STEP 5: ANALYSING 2 (Tests if the battery can absorb charge)
STEP 6: CONSTANT OUTPUT CHARGE (Charges with constant voltage and compensates fake full charge
caused by high current charging)
STEP 7: RECOVERY CYCLE CHARGE (Absorbs more charge and compensates side effect of reduced
charging current)
STEP 8: ABSORPTION (Charges with constant trickle current for maximum battery voltage)
STEP 9: ANALYSING 3 (Tests if the battery can hold charge)
STEP 10: MAINTENANCE (Continuously monitors the battery, and charges with trickle current once the
voltage is lower than threshold)

CONNECTION TO MAINS SUPPLY
MAINS SUPPLY
The electrical supply required for this product is in excess of 13 amp, NO plug is fitted.
You must therefore contact a qualified electrician to ensure that a suitable power
supply is available. We recommend the use of an industrial round pin plug and socket
(IEC60309) this should be discussed with your electrician. Use of an RCD to protect this
circuit is recommended.
MAINS PLUG
This charger must be correctly earthed via a three-pin plug, as shown.
a) Connect the green/yellow earth wire to the earth terminal.
b) Connect the brown live wire to live terminal ‘L’.
c) Connect the blue neutral wire to the neutral terminal, ‘N’ or unmarked.
d) After wiring, check that there are no bare wires, that all wires have been correctly
connected, that the external insulation extends beyond the cable restraint and that
the restraint is tight.
EXTENSION CABLES
If an extension reel is used it should be fully unwound before connection. The cable
conductor core section is important and should be at least 1.5mm² for MP726 and
2.5mm² for MP727, use of long extension cables will also affect performance and the
shortest suitable length should be selected.
HANDLE INSTALLATION
To install the handle - pull the clamp storage panel found on the rear of the charger
upwards to remove it. Press the spring clips on the handle and insert into the 2 holes
on the rear of the charger. Ensure the spring clips are fully locked into the retaining
holes. The handle can be fully retracted for compact storage.
To remove the handle –use a tool (ie screwdriver) to press the spring clips into the
retaining holes. Pull the handle out of the 2 holes on the rear of the charger.

PREPARATION OF THE BATTERY
Refer to the vehicle manufacturer’s handbook for battery maintenance and charging
guidelines.
If the battery must be removed from the vehicle before charging, ensure all other
electrical loads in the vehicle are switched off. Always disconnect the earthed
connector from the battery first.
CONNECTION
Always disconnect the mains supply before making or breaking battery connections.
Ensure the battery poles are clean. Connect the battery clips to the battery in the
following order:
First connect the positive charging lead (RED) to the positive post of the battery
(marked +, +ve or P).
Then for vehicles with the battery still installed: connect the negative charging lead
(BLACK) to the vehicle chassis (marked -, -ve or N), well away from the battery, fuel
line, hot or moving parts.
For batteries removed from the vehicle: Connect the negative charging lead (BLACK) to
the negative post of the battery (marked -, -ve or N).
After connecting the clips, rotate them slightly so as to remove any dirt or oxidization,
thus ensuring a good contact. The charger must now be connected to the mains
supply.
CHARGING
When correctly connected to a battery and to the mains supply, the charger will detect
the battery voltage (12V-24V) and display the voltage measured on the “Main Display”
(1).
Select the correct battery type “Battery Type” (7).
Select an appropriate current rate “Current rate selector” (9).
Select charge on the “Function selector” (11).

mains socket and then disconnect the clips in the following order:
Remove thenegative (BLACK lead) first. Then disconnect the positive (RED lead) from
the battery.
ABORTED CHARGES
lf charging cannot be completed normally, charging will be aborted.The digital display
may show an Error code. To reset the charger after an aborted charge, unplug the
charger, disconnect the battery and then after checking the battery and connections
reconnect correctly.
OVERHEAT PROTECTION
The charger is designed to shut itself off if overheating is detected (see trouble shooting).
Once the charger cools down, it will resume charging automatically.
ENGINE START FUNCTION
The charger’s “engine start function” (13) can be used to help start vehicles with a weak
battery. In very low temperatures or if the battery voltage is below 1V it is better to
allow pre-charging of the battery for at least 4 minutes before jump starting.
1). Connect the charger as described under “Connection”.
2). Press “Function Selector” (11) until the “Start” (13) LED indicator is illuminated.
3). Crank the engine until it starts or 5 seconds pass. If the engine does not start, wait 4
minutes before cranking again. This allows the battery and charger to cool down.
4). During the engine start process the “digital display” (1) will show START READY –the
charger is waiting for the engine to be cranked before delivering the amps for the
engine start.
5). Once cranking is detected, the charger will automatically deliver up to its maximum
output required by the starting system for up to 5 seconds.
6). After cranking the charger enters a mandatory 240 seconds cool down state. The
“digital display” (1) indicates the remaining cool down time in seconds. After 240
seconds the “digital display” (1) will show START-READY.

battery terminal.
9). Disconnect the red (+) terminal connection cable with clamp from the positive
battery terminal.
REPAIR FUNCTION
The charger’s “repair function” (14) can be used to to repair old, idle or sulphated
batteries. Not all batteries can be recovered. If possible for optimum results take the
battery through a full charging cycle before using this function. This mode uses a high
charging voltage and may cause some water loss in WET cell batteries. As some
batteries and electronics may be sensitive to high charging voltages, it is advised to
disconnect the battery from the vehicle before using this mode.
1). Connect the charger as described under “Connection”.
2). Press “Function Selector” (11) until the “Repair” (14) LED indicator is illuminated.
