East Penn / Deka High Rate Series

The annual Maintenance Routine consists of the following:

1. Perform Midtronics internal conductance readings as well as interjar / inter-tier impedance readings on all batteries.
2. Rehabilitate up to 20% of all connections as required by above test and inspection. All connections requiring rehabilitation over the 20% limit will be billed on a time and material basis.
3. Verify proper torque of all bolted connections.
4. Clean and neutralize all cells and racks/cabinets.
5. Measure and record all individual jar and string float voltages and AC ripple current.
6. Individual cell inspection; seals, posts, jar integrity.
7. Record ambient temperature of battery room.
8. Record Date Code, Battery Post Type, interconnect cable size, hardware/connection type.
9. Verify integrity of the battery rack/cabinet.
10. General cleanliness of the battery and battery room.
11. Individually High Rate/Short Term load test all jars to verify integrity and recovery curve. (when required)
12. Furnish completed data sheets and report any problems found during the inspection.

The Semi-Annual or Quarterly Maintenance Routine consists of the following:

1. Perform Midtronics internal conductance readings as well as interjar / inter-tier impedance readings on all batteries.
2. Measure and record individual jar and string float voltages and AC ripple current.
3. Clean all cells and racks, provide corrosion control where required.
4. Record ambient temperature of battery room.
5. Record Date Code, Battery Post Type, interconnect cable size, hardware/connection type
6. Individual cell inspection; seals, posts, jar integrity.
7. Individually High Rate/Short Term load test all jars to verify integrity and recovery curve. (when required)
8. Furnish completed data sheets and report any problems found during the inspection.

Note 1: The intervals of service visits and intervals of load testing can be adjusted based on the following:
1. Battery Type
2. Age
3. Customer’s personnel requirements

Note 2: Batteries and replacement labor are specifically excluded from this agreement. This program provides for inspections “only”.

The Quarterly Maintenance Routine consists of the following:

1. Measure and record the specific gravity of every cell.
2. Measure and record individual cell and string float voltages.
3. Clean all cells and racks, provide corrosion control where required.
4. Adjust electrolyte levels as required.
5. Record temperature of electrolyte of representative pilot cells.
6. Individual cell inspection; seals sediment levels, positive and negative plates, flame arrestors, electrolyte levels.
7. Provide computer analysis and historical archiving of all battery data and furnish a Quarterly Maintenance Routine Report.
8. All distilled water to be supplied by customer or billed to customer.

Note: The intervals of service visits and intervals of load testing can be adjusted based on the following:

1. Battery type
2. Age
3. Customers personnel requirements
4. Environmental Conditions

The annual Maintenance Routine consists of the following:
