Setup and Installation
Proper setup is crucial for the optimal performance and longevity of your Enersys Cyclon battery. Follow these guidelines carefully:
1. Initial Inspection
Upon receiving the battery, inspect it for any signs of physical damage. Ensure the terminals are clean and free from corrosion. Do not use the battery if it appears damaged.
2. Environmental Conditions
Install the battery in a clean, dry, and well-ventilated area. Avoid locations with extreme temperatures, direct sunlight, or high humidity. The recommended operating temperature range is typically between -65°C to +80°C, but optimal performance and float life are achieved around 25°C.
3. Connection Guidelines
Connect the battery to your equipment using appropriate cables and connectors. Ensure correct polarity: connect the positive (+) terminal of the battery to the positive terminal of your device, and the negative (-) terminal to the negative terminal. Incorrect polarity can damage the battery and connected equipment.

4. Initial Charging
While Cyclon batteries are shipped with a charge, it is recommended to fully charge the battery before its first use, especially if it has been stored for an extended period. Use a charger specifically designed for sealed lead-acid batteries with a 2-volt output. Refer to the charger's instructions for proper charging procedures.
Operating Instructions
The Enersys Cyclon battery is designed for reliable performance in various applications. Observe the following during operation:
1. Discharge Characteristics
The Cyclon battery provides a high stable voltage delivery due to its low internal resistance. This results in a flat discharge voltage profile, ensuring consistent power output throughout its discharge cycle. Avoid deep discharges below the recommended voltage levels to maximize battery life.
2. Charging During Operation
For applications requiring continuous power, the battery can be kept on a float charge. Ensure the charging voltage is within the manufacturer's specified range for 2-volt sealed lead-acid batteries to prevent overcharging or undercharging.
3. Safety Precautions
Although Cyclon batteries are sealed and non-spillable, always handle them with care. Do not short-circuit the terminals. Avoid exposing the battery to open flames or excessive heat. Ensure proper ventilation if the battery is enclosed, even though gassing is minimal under normal conditions.
Maintenance
Enersys Cyclon batteries are maintenance-free due to their sealed, non-spillable design. However, periodic checks can help ensure optimal performance and longevity:
1. Terminal Inspection
Periodically check the battery terminals for cleanliness and tight connections. Clean any dust or dirt with a dry cloth. Do not use abrasive cleaners or solvents.
2. Storage
If the battery is to be stored for an extended period, ensure it is fully charged before storage. Store in a cool, dry place away from direct sunlight and extreme temperatures. Recharge the battery every 6-9 months during storage to prevent self-discharge and maintain capacity.
3. Battery Disposal
Do not dispose of the battery in household waste. Sealed lead-acid batteries contain recyclable materials and should be recycled according to local regulations. Contact your local recycling center for proper disposal instructions.
Troubleshooting
This section addresses common issues you might encounter with your Enersys Cyclon battery.
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not holding charge | Undercharging; End of life; Internal damage | Ensure charger is compatible and functioning correctly. Fully charge the battery. If issue persists, battery may need replacement. |
| Low voltage output | Battery discharged; Loose connections; Overload | Recharge the battery. Check and tighten all connections. Ensure the load does not exceed battery capacity. |
| Battery not charging | Faulty charger; Incorrect connection; Battery fault | Verify charger functionality with another battery or device. Check polarity and connections. If battery is severely discharged, it may not accept charge. |
