Setup
1. Unpacking and Inspection:
- Carefully remove the battery from its packaging.
- Inspect the battery for any signs of damage, such as cracks, leaks, or corroded terminals. Do not use a damaged battery.
2. Placement:
- Place the battery in a clean, dry, well-ventilated area, away from direct sunlight and heat sources.
- Ensure the battery is placed on a level, non-conductive surface.
- Maintain sufficient clearance around the battery for air circulation.
3. Initial Preparation (if applicable):
- Some wet cell batteries may require initial filling with electrolyte (sulfuric acid solution) or distilled water. Refer to any specific instructions included with your battery for initial preparation. This battery is typically shipped pre-filled.
- If adding water, use only distilled water. Do not use tap water.
4. Connecting to the Sump Pump System:
- Refer to the instruction manual of your specific sump pump backup system for detailed wiring diagrams and connection procedures.
- Ensure the sump pump system's power is OFF before making any connections.
- Connect the positive (+) terminal of the battery to the positive (+) terminal of the sump pump system.
- Connect the negative (-) terminal of the battery to the negative (-) terminal of the sump pump system.
- Ensure all connections are tight and secure to prevent arcing and ensure optimal performance.
- Apply a thin layer of dielectric grease or anti-corrosion spray to the terminals to prevent corrosion.
Operating
Once properly installed and connected to a compatible sump pump backup system, the Zoeller Aquanot battery operates automatically.
- The sump pump backup system will monitor the main power supply and the battery's charge level.
- During a power outage, the system will automatically switch to battery power, allowing the sump pump to continue operating.
- The battery is designed to provide approximately 5-7 hours of continuous run time, depending on the load of the sump pump and its frequency of operation.
- When main power is restored, the sump pump system's charger will automatically recharge the battery.
Maintenance
Regular maintenance is crucial for extending the life and ensuring the reliability of your wet cell battery.
1. Check Electrolyte Levels (Monthly):
- With the battery charger disconnected, carefully remove the vent caps.
- Check the electrolyte level in each cell. The liquid should cover the plates by approximately 1/2 inch (1.25 cm) or reach the designated fill line.
- If the level is low, add only distilled water until the correct level is reached. Do not overfill.
- Replace the vent caps securely.
2. Clean Terminals (Quarterly or as needed):
- Disconnect the battery from the sump pump system.
- Inspect terminals for corrosion (white or bluish powder).
- Clean corroded terminals with a wire brush and a solution of baking soda and water (1 tablespoon baking soda per cup of water).
- Rinse with clean water and dry thoroughly.
- Apply a thin layer of dielectric grease or anti-corrosion spray to the clean terminals before reconnecting.
3. Check Connections (Quarterly):
- Ensure all battery cable connections are tight and secure. Loose connections can cause poor performance and heat buildup.
4. Ventilation:
- Always ensure the battery area is well-ventilated to prevent the buildup of hydrogen gas, especially during charging.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not holding charge / Short run time | Low electrolyte level, sulfation, faulty charger, old battery. | Check and add distilled water. Ensure charger is functioning. Battery may need replacement if old or severely sulfated. |
| Sump pump not activating during power outage | Battery discharged, loose connections, faulty sump pump system. | Check battery charge. Verify all connections are secure. Consult sump pump system manual for troubleshooting. |
| Corrosion on terminals | Acid fumes, loose connections. | Clean terminals thoroughly and apply anti-corrosion agent. Ensure connections are tight. |
| Battery overheating during charge | Overcharging, poor ventilation, internal battery fault. | Ensure proper ventilation. Check charger output. Discontinue use if overheating persists and consult a professional. |
