Usage Features:
- Installation: Cells should be unpacked upon delivery and inspected for damage. If supplied filled and charged, the acid level must be at MAX. Dry-charged batteries can be stored for up to 3 years if protected from condensation and high humidity. Cells should be installed on suitable racks, ensuring proper spacing for inter-cell connectors and easy access for maintenance. Terminal posts and connectors must be cleaned and coated with no-oxide grease. Torque settings for connectors are 70 inch-pounds (8 Nm) for BLSe block batteries and 90 inch-pounds (10 Nm) for LSe cells.
- Charging:
- Initial Charge for Dry Cells: After filling with electrolyte, dry cells require an initial charge as soon as possible (within 18 hours). The electrolyte temperature should not exceed 95°F (35°C). A constant voltage charger (2.23 to 2.6V/cell) with adjustable current (0 to 0.10 C8 Amps) is recommended. Charge at 0.10 C8 Amps for 20 hours, then continue until specific gravity and voltage are constant for two hours and each cell reaches a minimum of 2.6V. Total Ah delivered should be 150-160% of C8 rated capacity.
- Freshening/Commissioning Charge for Filled and Charged Cells: Batteries supplied filled and charged require a freshening charge to compensate for charge loss during transit/storage. This is typically done using the "equalize" voltage setting (2.33-2.4 V/cell). The charge can be terminated when specific gravity readings remain constant for at least 2 hours.
- Float Charge (in Service): To maintain a fully charged state, a recommended float charge of 2.23 V/cell with 1.240 SG electrolyte at 77°F (25°C) should be applied. This minimizes gassing and water consumption.
- Equalize Charge (in Service): Required when voltage spread between cells exceeds 0.04V, for fast recharging after discharge, after adding de-ionized water, or for float charges below 2.22 V/cell. Recommended equalize voltage is 2.33-2.4 V/cell, continued until pilot cell specific gravity is constant for 2 hours.
Maintenance Features:
- Safety Rules: Emphasizes the importance of safety due to explosive gases and corrosive sulfuric acid. Protective clothing, rubber gloves, and goggles are mandatory. Immediate washing with water is required for acid contact. Insulated tools, avoiding metal objects on batteries, and removing jewelry are crucial. Smoking, open flames, and electric sparks are prohibited. First aid kits, fire extinguishers, and water facilities must be accessible. Neutralizing products for spills are recommended.
- Battery Room: Must be dry, clean, free of vibration, and properly ventilated. Temperature should be between 50°F (10°C) and 80°F (27°C) for optimal performance, with a functional range of 0°F (-18°C) to 125°F (52°C). Warning signs for no smoking/sparks are required. Racks should be suitable and acid-proof, with insulators if made of steel. Maximum temperature differential between cells should not exceed 5°F (3°C).
- Specific Gravity: Readings must be corrected for temperature (subtract 1 point for every 3°F above 77°F, add 1 point for every 3°F below 77°F; or 1 point for every 1.5°C). Electrolyte should never be added to increase specific gravity unless directed by the manufacturer.
- Maintenance Program: A good program prolongs battery life and prevents failures. A pilot cell (one for every 60 cells) should be selected for regular monitoring.
- Monthly Inspection:
- Check general appearance, cleanliness of battery, rack, and area.
- Check for cracks or electrolyte leakage.
- Check for corrosion at terminals, connectors, or racks.
- Record overall battery float voltage.
- Record voltages, temperature, and specific gravity of pilot cells.
- Check electrolyte level.
- Clean and dry cell lids and connectors using anti-static cloths.
- Inspect charging system, ambient temperature, and ventilation.
- Take corrective actions per IEEE standard 450.
- Annual Inspection: Includes all monthly checks, plus:
- Record voltages of all cells to three decimal places.
- Record electrolyte temperature and specific gravity of designate pilot cells.
- Tighten all connectors (torque settings in section 7.0).
- Record inter-cell and terminal connections resistance.
- Record charging current.
- Check structural integrity of battery racks.
- Topping-up: Water consumption is minimized at 2.23V/cell at 77°F (25°C). Electrolyte level must not fall below the "MIN" line. Only de-ionized water should be used for topping up. Never add electrolyte unless directed by the manufacturer.
- Maintenance Report: Keep detailed records of all maintenance operations, measurements, outages, discharge tests, equalize charges, and topping intervals to monitor long-term battery condition.
- Discharge Test: A full discharge test should be performed at 5-year intervals until degradation is observed or capacity reaches 85% of original. After that, tests should be annual until end of life.
- Recycling: Used batteries contain hazardous and recyclable materials and must not be disposed of with normal waste. Recycling methods must conform to federal, state, and local regulations.
