East Penn Manufacturing Co. Battery Pack Fahrenheit

1. Conduct a visual inspection of each battery.

2. Record the battery string voltage at battery terminals while battery is on float charge.

3. Record the charger voltage at charger panel meter.

4. Record the individual battery voltages. The accuracy of the DMM (Digital Multimeter) must be 0.05% (on dc scale) or better. The DMM must be calibrated to NIST traceable standards. Because float readings are affected by discharge and recharges, these readings must be taken when the battery string has been on continuous, uninterrupted float for at least one month. Battery should be within ± 0.30 volts of the average battery string voltage.

5. Record the ambient temperatures.

6. Record the battery string temperature at the negative terminal.

7. Record individual battery Ohmic readings.

8. Record all interbattery 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.

Retourque value is equal to initial torque value as indicated in BATTERY ASSEMBLY section. Recheck the micro-ohm reading. If the reading remains high, clean the contact surface according to installation portion of this manual.

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.” When performing capacity testing and recording data refer to IEEE 1188 recommendations.

NOTE: When discharging at higher rates, extra connectors may need to be added to prevent excessive voltage drop and/or excessive temperature rise. Should it be determined that only individual battery(ies) need to be replaced, contact East Penn.

Do not use any chemical compounds to clean batteries.; Batteries, cabinets, and racks, shall only be cleaned with: clear water, a mixture of baking soda and water or East Penn Mfg battery cleaner (part # 00321).

Any other types of chemical compounds or solvents other than listed above, to clean the battery may damage the battery case and / or cover causing possible exposure to sulfuric acid.;
