1.2. Battery Charger Safety

DANGER! BE AWARE, LEAD-ACID BATTERIES GENERATE EXPLOSIVE GASES DURING NORMAL BATTERY OPERATION. FOR THIS REASON, IT IS VERY IMPORTANT TO READ AND FOLLOW THESE INSTRUCTIONS CAREFULLY, EACH TIME YOU USE THE CHARGING EQUIPMENT.

• Follow these instructions and those published by the battery and vehicle manufacturers, and the maker of any equipment you intend to use in the vicinity of the battery. Remember to review warning marks on all products and on engines.
• WARNING! Modern vehicles contain extensive electronic systems. You are required to check with the vehicle Manufacturer, for any specific instructions regarding the use of this type of equipment on each vehicle. No liability will be accepted for damage / injury, where this product is not used in accordance with all instructions.

1.3. Personal Precautions

• Ensure there is another person within hearing range of your voice and close enough to come to your aid, should a problem arise when working near a lead-acid battery.
• Wear safety eye protection and protective clothing. Avoid touching eyes while working near battery.
• Have fresh water and soap nearby in case battery acid contacts skin, clothing or eyes.
• Wash immediately with soap and water if battery acid contacts skin or clothing. If acid enters eye, flush eye immediately with cool, clean running water for at least 15 minutes and seek immediate medical attention.
• Remove personal metallic items such as rings, bracelets, necklaces and watches. A lead-acid battery can produce a short-circuit current which is high enough to weld a ring or the like to metal, which would cause severe burns.
• Ensure hands, clothing (especially belts) are clear of fan blades and other moving or hot parts of engine, remove ties and contain long hair.
• ❌ DO NOT smoke or allow a spark or flame in the vicinity of battery or engine.

1.4. General Safety Instructions

• Ensure the charger is disconnected from the mains supply before attaching/detaching the power clamps to/from the battery.
• Keep tools and other items away from the engine and ensure you can see the battery and working parts of engine clearly.
• Ensure the output of the charger is the same voltage as the battery.
• Ensure that during charging, the charger is placed in a location where there is sufficient ventilation to prevent the build up of explosive gases from a lead acid battery, and ❌ DO NOT cover or obstruct the charger ventilation louvres.
• If battery has caps to access the battery fluid, remove the caps and check the fluid level before connecting the power clamps. If necessary top-up the battery with distilled water by referring to the battery manufacturer's instructions (Apply the personal safety precautions described in part 1.3).

• Stage 1: Desulphation: Pulses of current and voltage.
• Stage 2: Battery charge to 25% capacity using 50% constant current.
• Stage 3: Battery charge to 50% capacity using max. current.
• Stage 4: Battery charge to 75% capacity using constant voltage.
• Stage 5: Analysis: Analysing power capacity.
• Stage 6: Recond: If power capacity is low use Recond to attempt recovery.
• Stage 7: Battery charge to 100% capacity using constant voltage.
• Stage 8: Diagnosis: Check battery for 100% charged.
• Stage 9: Maintenance: Battery fully charged.

Connecting to the Battery
