5. The Charging Process

The Charging LED’s will indicate the Charging Stages. LCD will display

the values and functional setting.

The charging stages are as follows:

Soft Start: Charges the battery using half the maximum current

until the battery voltage is over 22V (indicated by

YELLOW Bulk

LED FLASHING). Soft Start occurs if the initial voltage is less than

22V (due to severe-deep discharge)

Bulk Charge: Charges using a constant maximum current until

the battery rises to the Absorption level = 85% full (indicated by the

YELLOW Bulk LED ON)

Absorption: This stage charges the battery using a constant

voltage providing that the Battery Voltage is over 85% (indicated by

the

BLUE

Absorption LED ON) .

Equalization: Mode is only activated by calling VDC Electronics

Technical Support at (800) 379-5579 x206.

Do not use unless

battery is removed from aircraft.

Regular use of this mode may

damage battery.

Mode ensures full charge to ageing-marginal

batteries and improves performance on capacity tests.

Float / Full: Battery is in Float stage and fully charged, it will be

maintained at a safe voltage and ready for use. (The

GREEN

Float

LED ON - indicates the battery is fully charged).

Desulfation: Mode is activated by pressing “Desulfation” button.

Do not use unless battery is removed from aircraft.

Disconnecting BatteryMINDer from Battery.

(a) If the Battery is not in end-use installation:

Switch OFF AC power switch, remove the AC Power Socket from

the outlet.

Remove the

BLACK

lead and then the

RED

lead, remove the Sensor

Check electrolyte levels if possible (may need topping up with distilled

water after charging)

(b) If Battery is in end-use installation:

Switch OFF AC power switch, remove the AC Power Socket

from the outlet.

Remove leads from battery. Remove Sensor A.

Check electrolyte levels if possible (may need topping up with

distilled water after charging).
