OPERATING INSTRUCTIONS
INSTRUCTIONS FOR USE
1. Charging your battery
It is essential to disconnect the battery from the car. This will avoid possible damage to the
alternator. To avoid damage to the bodywork from possible spillage, remove the battery
from the vehicle. We recommend the use of disposable gloves to do this as there is a high
possibility of corrosive acid being on the outside of the battery.
2. Preparing the battery
If you have a maintenance-free/permanently-sealed
battery it is not necessary to carry out the following
checks. First remove the caps from each cell and check
the level of the liquid. If below the level as marked on
the side of the battery, top up with de-ionized or distilled
water. Under no circumstances should tap water be used.
The cell caps should not be replaced until charging is
completed. This allows any gases formed during charging
to escape. However, some minor escape of acid will occur
during charging.
IMPORTANT
If your battery is the AUTOFIL type, manufactured be Dagenite or Exide, the glass balls and
the long filler cap must be left in place during charging.
3. Charging options
The voltage selection switch (2) on the front panel offers two charging options. Select the
correct position BEFORE connecting the charger to a battery or AC power source (mains
supply).
- 6V
When charging a 6 volt lead acid battery switch the voltage selector to 6V position.
- 12V
