CHARGING INSTRUCTIONS
STEP 1 – PRE-CHARGE CHECK AND ELECTROLYTE LEVEL CHECK
• Check the battery electrolyte level (not required on sealed and maintenance-free batteries).
If necessary, remove the vent caps and add distilled water so the levels are halfway between the upper and lower fill lines.
STEP 2 - CONNECTING THE BATTERY CHARGER TO YOUR BATTERY
• If the battery is o
ut of the vehicle
:
- Connect the Red (+) battery charger lead to the positive (+) battery terminal.
- Connect the Black (-) battery charger lead to the negative (-) battery terminal.
• If Battery is still
in the vehicle
, determine if the vehicle is positively or negatively earthed.
- If negatively earthed (most common) – FIRST Connect the Red (+) battery charger lead to the positive (+) Battery
post and then connect the Black (-) battery charger lead to the vehicle’s chassis and away from the fuel line.
- If Positively Earthed – FIRST Connect the Black (-) battery charger lead to the Negative (-) battery post and then connect
the Red (+) battery charger lead to the Vehicle’s chassis and far away from the fuel line.
STEP 3 - CONNECT THE BATTERY CHARGER TO MAINS POWER
• Connect the battery charger to the mains power socket.
• The charger will automatically start when AC power is connected and switched on. (Note: If the Fault Indicator LED illuminates
red, please check your connections as it’s likely that the positive and negative leads are reversed. Refer to Trouble Shooting
Page for further information).
