4. Setup and Installation
Follow these steps for proper installation of your EnerSys Genesis NP7-12 battery:
- Inspect the Battery: Before installation, visually inspect the battery for any signs of damage, cracks, or leaks. Do not install a damaged battery.
- Prepare the Installation Area: Ensure the installation area is clean, dry, and well-ventilated. Avoid locations with excessive heat or direct sunlight.
- Identify Terminals: Locate the positive (+) and negative (-) terminals on the battery. The positive terminal is typically marked with a red indicator or a plus sign, and the negative with a black indicator or a minus sign.
- Connect Cables: Connect the positive cable from your device or charging system to the positive (+) terminal of the battery. Then, connect the negative cable to the negative (-) terminal. Ensure connections are secure and tight to prevent arcing or poor performance.
- Verify Polarity: Double-check that the polarity is correct before applying power. Incorrect polarity can damage the battery and the connected equipment.
- Secure the Battery: If applicable, secure the battery in its compartment or mounting bracket to prevent movement during operation.

5. Operating Instructions
The EnerSys Genesis NP7-12 battery is designed for reliable power delivery. Proper charging is crucial for its lifespan and performance.
Charging Guidelines:
- Float Charge Voltage: For standby applications, maintain a float charge voltage between 13.5 - 13.8V at 25°C (77°F). This voltage helps keep the battery fully charged without overcharging.
- Cyclic Charge Voltage: For applications involving regular discharge and recharge cycles, use a cyclic charge voltage between 14.4 - 15V at 25°C (77°F).
- Temperature Compensation: Charging voltages may need adjustment based on ambient temperature. Consult your charger's manual for temperature compensation guidelines.
- Charger Compatibility: Use a charger specifically designed for sealed lead-acid batteries with appropriate voltage and current ratings.
- Ventilation: Always ensure good ventilation during charging to dissipate any potential gases.
6. Maintenance
The EnerSys Genesis NP7-12 is a maintenance-free battery, meaning it does not require water additions. However, regular checks can help ensure its longevity and performance.
- Keep Clean: Periodically inspect the battery and terminals for dirt, dust, or corrosion. Clean terminals with a wire brush and a solution of baking soda and water if corrosion is present. Ensure terminals are dry before reconnecting.
- Terminal Connections: Ensure all terminal connections remain tight and secure. Loose connections can lead to resistance, heat buildup, and reduced performance.
- Temperature Control: Avoid prolonged exposure to extreme temperatures. High temperatures can accelerate battery degradation, while very low temperatures can reduce capacity. Optimal operating temperature is around 25°C (77°F).
- Storage: If storing the battery for an extended period, ensure it is fully charged and store it in a cool, dry place. Periodically check the voltage and recharge if necessary to prevent deep discharge.
- Ventilation: Always ensure the battery is in a well-ventilated area, especially during charging.
