East Penn Manufacturing Co. Battery Pack AVR45

1. Disconnect battery system from power source.

2. Dust accumulation can be removed with cloth dampened with clean water.

3. Corrosion buildup should be neutralized using a mixture of baking soda and water or East Penn Mfg supplied battery cleaner (part # 00321).

4. Use cloth dampened with clean water to remove residue. Never use solvents to clean the battery.;

1. Conduct a visual inspection of each cell.

2. Record the battery string 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 discharges 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;
