Operating Instructions

The Oximiser 900 features a 5-stage automatic battery management system:

1. Recovery: For deeply discharged batteries (as low as 4.1 Volts, if undamaged), the charger will initiate a varying charge rate to recover the battery.
2. Bulk Charge: Charges the battery to its full capacity.
3. Optimization: Ensures the battery is kept in optimal condition and never drops below the critical voltage level of 12.6 Volts.
4. Maintenance: Once fully charged, the Oximiser 900 can be left permanently connected for long-term battery care, providing ongoing monitoring and charging only when needed.
5. LCD Screen: The unique LCD screen with backlighting provides real-time information, including the actual voltage and amperage, and a mobile phone-style battery indicator for state of charge.

The Oximiser 900 is suitable for all 12 Volt battery types up to 30 Ampere/hour, including Gel, MF, and conventional lead-acid batteries.

Maintenance

The Oxford Oximiser 900 is designed for minimal maintenance. Simply ensure the connections are clean and secure. The automatic battery management system handles the charging and maintenance cycles without user intervention.

• Regularly inspect cables and connectors for any signs of wear or damage.
• Keep the charger unit clean and dry.
• For long-term storage, ensure the charger remains connected to maintain optimal battery health.

Troubleshooting

• Charger Not Activating: Ensure the charger is properly plugged into a live power outlet and securely connected to the battery terminals. The Oximiser 900 can recover batteries as low as 4.1V, but if the battery is severely damaged, it may not initiate charging.
• Battery Not Charging: Verify that the battery type is compatible (12V, up to 30Ah, Gel, MF, or acid). Check for any loose connections or corrosion on the battery terminals.
• Overheating: The Oximiser 900 is designed to prevent overcharging. If the unit feels excessively hot, disconnect it immediately and check for proper ventilation and battery condition.
