Periodic Maintenance; Quarterly Inspection; Semiannual Inspection - C&D Technologies TEL Series Installation And Operating Procedures

VIII. Initial Installation Data
The following initial installation data should be maintained on site:
•
Date and Initial open circuit voltage of unit(s) at time of delivery to the site.
•
Freshening charge records, if performed.
•
Initial torque value used for connections.
•
Overall system float voltage across battery terminals.
•
Individual unit float voltage.
•
Internal Ohmic value of each unit.
•
Connection resistances.
•
Float current.
IX. Periodic Maintenance
These VRLA batteries are maintenance free with respect to the electrolyte. However, the charging voltage,
temperature, performance and connection resistances must be periodically monitored and any necessary
corrective actions taken if irregular values are observed to assure reliable standby power when required.

Quarterly Inspection

•
Measure and record the system total float charging voltage at the battery terminals
•
Record the charger on charge output current and voltage
•
Record the ambient temperature and condition of ventilation equipment
•
Visually inspect the batteries and rack for general appearance, cleanliness or any irregularity.
•
If gas tubing provisions are utilized, check for any obstructions in the tubing which would prevent
the free flow of gases thru the exit point.

Semiannual Inspection

•
Repeat the quarterly checks
•
Record the on charge voltage of each unit
•
Optionally perform and record Ohmic checks for trending purposes
Yearly and Initial Inspection
•
Repeat the semiannual checks
•
Inspect all connections to ensure integrity.
