4.3.4. The charging status of a battery will be displayed digitally in the LED window of the charger, it can also be determined by use of a hydrometer which measures the specific gravity of the electrolyte. The following information indicates kg/l at 20°C:
1.28 = Fully charged
1.21 = Half charged
1.14 = Fully discharged battery.
‰ WARNING! Take care as the electrolyte is highly corrosive.
4.4. CHARGING THE BATTERY – Referring to the graphs (fig.6 and fig.7), the projected voltage is represented by the lower line and the projected current is represented by the upper incremental line. Stages and time are represented by the numbers 1 – 9 (fig.6) for lead acid batteries and 1 – 10 (fig.7) for lead calcium acid batteries.
4.4.1. Select the required charging mode (fig.3) by pressing the “MODE” button (fig.4). The ‘vehicle’ icon indicates normal charging, the ‘snowflake’ icon indicates low temperature environment charging, the ‘Cal’ indicates calcium type battery charging and is also a repair mode for sulphated batteries. The ‘battery clips’ icon indicate battery support mode, this mode provides power for the battery during prolonged electronic diagnostic checks. If either the ‘Cal’ icon or the ‘battery clip” icon mode is required; from the initial flashing “000” standby mode, press the mode button in quick succession (before the “R E P” appears in the LED window) and follow the illuminated icon indicators to the required mode. Press three times for “Cal”, four times for ‘battery clips’, five times for back to standby status. For further explanation of charging modes see table fig.6. If a charging mode selection is made, after a few seconds “R E P” appears in the LED window; this extinguishes after 5 flashes to read the selected ‘voltage/current/charging %’ from fig.4. Selection of ‘Cal’ (amber) and ‘battery clip icon’ (red) are now inhibited and cannot be selected.

4.4.2. Select the required 3 figure digital display by pressing the “display” button (fig.3) for ‘voltage’, press again for ‘current’ and again for ‘charging %’. The exclamation mark indicates a fault condition. Inboard short circuit protection and overload protection instantly shuts the charger down in a fault condition. For further explanation of displayed LED readings see table fig.5.

4.4.3. Check the current delivery to the battery by pressing the “display” button (fig.3). Initially, there will be a high rate of charge which will decrease slowly according to the capacity and condition of the battery. Press again for ‘current’ and again for ‘charging %’ values.
4.4.4. When fully charged the ammeter reading ‘current’ should be “0.00” or close to “0.00” and the electrolyte in the battery should begin to gas (not visible on vented sealed for life modern batteries). Press the “display” button to check the ‘charging %’, if the LED reads
4.4.5. “F U L” the battery is fully charged. If the LED reads “C H E” (stage 9 in graphs), wait whilst the charger checks the battery. If the battery is charged fully the LED will normally change to “F U L” within 60 seconds.
4.4.6. Unless battery support mode is required, isolate mains power and unplug charger from the mains. On completion of all tasks disconnect the power clamps, the earthed clamp first, clean the charger and store in a safe, dry area.
4.4.7. Replace the battery electrolyte cover or caps when applicable. Wipe up any splashes or spillage. Return the battery to the vehicle, if required, secure according the manufacturer’s instructions and re-connect the power leads. Check to ensure all tools are removed before closing the bonnet.
