Consult “Hardware Torque Requirements” (pg 5) for proper torque values.

Final Assembly Check Procedure

1. For future identification of all cells, number individual cells in electrical connection sequence, beginning with number one (1) at the positive end of the battery. The last cell of the battery is located at the negative output terminal.

2. Read and record the voltages of the individual cells to assure that they are connected properly. The total battery voltage should be approximately equal to the number of cells connected in series, multiplied by the measured voltage of one cell If the measured is less, recheck the connections for proper polarity. Verify that all cells and battery connections have been properly torqued.

3. Measure and record the intercell connection resistance using a micro-ohms meter. This helps determine the ade-quacy of initial connection installation and can be used as a reference for future maintenance requirements. Refer to the recording forms in Appendix B of this manual.

Review the records of each connection and detail resist-ance measurements. Clean, remake, and remeasure any connection that has a resistance measurement greater than 10% of the average of all the same type connections (i.e. intercell, intermodule, etc.).

SYSTEM OPERATIONS

Charger Voltage These batteries are designed for continuous float applications.

Float / Standby

2.25 vpc ± 0.01 @ 77°F (25°C) When setting the float voltage on the charger, the system should be set to float at the nominal cell float voltage times the number of cells per string. The charger must be able to main-tain the system voltage within ± 0.5% of the desired level at all times. The desired float voltage varies with temperature according to the table in the next column.

Temperature Compensation Battery voltage should be adjusted for ambient temperature variations.

2mV per °C (1.8°F) per cell For temperatures above 77°F (25°C) subtract and for tempera-tures below 77°F (25°C) add.

Consult Voltage Compensation Chart in Appendix B for temperature compensation voltage maximum and minimum limits.

The average battery operating temperature should not exceed 95°F (35°C) and should never exceed 105°F (40.5°C) for more than an eight-hour period. Operating at temperatures greater than 77°F (25°C) will reduce the operating life of the battery.

If operating temperatures are expected to be in excess of 95°F (35°C), contact East Penn for recommendations.

Discharging at temperatures less than 77°F (25°C) will reduce the capacity of the battery.

Battery Voltage Although the charger must maintain the system voltage within ± 0.5%, individual cell voltages may vary by ± 0.05 volts of the average battery float voltage.

Equalizing Upon installation of the battery, an optional boost charge of

2.40 vpc ± 0.01 vpc for of 24 hours (not to exceed 24 hours) can be applied. (Note: Verify that the higher battery voltage will not adversely affect the other connected equipment.) If this is done, be sure to reset the charging equipment to the proper float voltage.

Cell Voltage Although the charger must maintain the system voltage with-in ± 0.5%, individual cell voltages may vary by ± 0.05 volts of the average cell float voltage.

Rectifier Ripple Voltage

FREQUENCY

Ripple that has a frequency greater than 667Hz (duration less than 1.5ms) is acceptable, unless it is causing addi-tional battery heating. Ripple that has a frequency less than 667Hz (duration greater than1.5ms), must meet the following voltage specification to be acceptable.

VOLTAGE

Ripple voltage shall be less than 0.5% peak to peak of the manufacturer’s recommended string voltage. Failure to comply can void the warranty.

RECORD KEEPING

Voltages, Temperatures & Ohmic Readings Record keeping is an important part of stationary battery maintenance and warranty coverage. This information will help in establishing a life history of the battery and inform the user if and when corrective action needs to be taken.

(Refer to Appendix A, Battery Maintenance Report) While it is acceptable to operate at temperatures less than 77°F (25°C), it will require longer charging time to become fully recharged. Also, the capacity will be less at operating temperatures below 77°F (25°C).

After installation and when the batteries have been on float charge for one week, the following data should be recorded:

1. Battery terminal voltage.

2. Charger voltage.

3. Individual cell float voltages.

4. Ambient temperatures.

5. Terminal connections should be checked to verify that the installer did torque all connections properly, consult “Hardware Torque Requirements” (pg 2) for proper torque values. Micro-ohm readings should be taken across every connection. Refer to meter manufacturer’s instructions for proper placement of probes. If any read-ing differs by more than 20% from its initial installation value, re-torque the connection, consult “Hardware Torque Requirements” (pg 5) for proper torque values.

If reading remains high, clean contact surfaces according to Step 1 under Connector Assembly.

6. Individual cell Ohmic readings. For 6-post cells, measure from center positive to center negative posts. Do not measure diagonally from positive to negative posts. See next page for specific location.

RECORD KEEPING CONT.

MAINTENANCE

Always wear eye protection when working on or near batteries.

Keep sparks and open flames away from batteries at all times.

Review Safety Precautions on pg. 1.

Annual Inspection (1)

1. Conduct a visual inspection of each cell.

2. Record the battery string voltage.

3. Record the charger voltage.

4. Record the individual cell voltages. The accuracy of the

DMM (Digital Multimeter) must be .05% (on dc scale) or better. The DMM must be calibrated to NIST traceable standards. Because float readings are affected by dis-charge and recharges, these readings must be taken when batteries have been on continuous, uninterrupted float for at least one month. Cells should be within ± 0.05 volts of the average cell float voltage.

5. Record the ambient temperatures.

6. Record individual cell Ohmic readings.

7. Record all intercell, interunit and terminal connection resistances. Micro-ohm readings should be taken during this inspection. If any reading differs by more than 20% from initial readings taken, retorque the connection.

Recheck the micro-ohm reading. If the reading remains high, clean the contact surface according to installation portion of this manual.

(1) Other Maintenance Inspection intervals follow

IEEE 1188

Battery Cleaning Batteries, cabinets, racks, and modules should be cleaned with clear water or a mixture of baking soda and water.

Never use solvents to clean the battery.

Capacity Testing Per IEEE 1188 “Capacity testing is used to trend battery aging.

The result of a capacity test is a calculation of the capacity of the battery. The calculated capacity is also used to determine if the battery requires replacement.”

Do not discharge the batteries beyond the specified final volt-age. When discharging at higher rates, extra connectors may need to be added to prevent excessive voltage drop and / or excessive temperature rise. Consult “Connector Packages” chart (pg. 15) for current limits. When performing capacity testing and recording data use IEEE 1188 instructions. Should it be determined that any individual battery(ies) or cell(s) need to be replaced, contact your nearest East Penn agent or East Penn Service Center.

CELL REMOVAL PROCEDURE

1. Before removing cell, review Safety Precautions on pg. 2 of this manual. Contact East Penn Mfg. Company, Inc. with specific questions or concerns.

2. Remove one cell at a time.

3. Confirm the lifting device is rated to handle the weight of one cell.

4. All tools used to remove the cell shall be insulated to avoid metal contact with battery posts.

5. Remove bolts from the retainer bar from the cell to be replaced.

6. Cells develop internal pressure. Relieving this pressure from the cell will make it easier to remove the cell from the sleeve assembly.

a. Pry off the vent shroud

b. Remove the flame arrestor

c. Loosen valve using a 17mm hex key approximately

½ turn to release the internal pressure. A cloth should be used to cover the valve when releasing pressure to avoid any chance of acid spray being released”
