GENERAL PROCEDURES
charging will not restore a battery to a full state of
charge and must therefore be followed by a period
of slow charging. Excessively fast charging can
cause damage to a battery. For this reason,
charging times must be carefully controlled. Fast
battery chargers vary widely in design so it is very
important to strictly adhere to the equipment
manufacturer‘s instructions. A charge of 30 amps
for up to 30 minutes is the most common fast
charging application. If the battery is very
discharged and requires additional restoration, an
additional charge of 20 amps for a period up to one
and a half hours should be applied. Fast charging
for a period in excess of two hours significantly
increases the risk of causing damage to the battery.
NOTE: When connecting and disconnecting the
battery from the vehicle, make sure that the battery
ground cable is disconnected first and connected
last and that all electrical items are switched off.
Record the audio unit keycode and preset radio
frequencies before disconnecting the battery.
1. Remove the battery (Focus C-MAX 2003.75,
Focus 2004.75, S-MAX/Galaxy 2006.50,
Mondeo 2007.50 only).
2. Disconnect the battery ground cable (All,
except the vehicles mentioned in the
previous step).
3. NOTE: The maximum battery electrolyte level
is approximately 40 mm below the very top
of the battery casing. This corresponds to a
point just below the lower rim of the battery
casing.
Check that the battery electrolyte reaches
the indicated maximum level. Top up with
distilled/de-ionized water, as necessary.
4. Connect the positive red clamp from the
battery charger to the positive battery
terminal.
5. Connect the negative black clamp from the
battery charger to the negative battery
terminal.
6. Connect the AC power cable to the mains
outlet and switch on.
7. Follow the instructions supplied with the
battery charger to charge the battery.
8. To disconnect the battery charger, reverse
the connection procedure.
