Exide Technologies Section 95.10 - Manual (Page 15)

SECTION 11 - MAINTENANCE SCHEDULE
A pilot unit is selected in the series string to reflect the general condition of all units in
the battery. The pilot unit should be the battery with the lowest voltage in the string
following the initial charge. By measuring the pilot unit voltage, it serves as an indicator
of battery condition between scheduled overall individual unit readings.
A complete recorded history of the battery operation is most desirable and helpful in
obtaining satisfactory performance. Good records will also show when corrective action
may be required to eliminate possible charging, maintenance or environmental
problems.
The following data should be read and permanently recorded for review by supervisory
personnel:
A. Upon completion of the initial charge and with the battery on float charge at the
proper voltage for one week, read and record the following:
1. Individual battery voltages
2. Battery string terminal voltages
3. Ambient temperature
B. Every 12 months, a complete set of readings as specified in Paragraph A above must
be done and all individual connections retorqued.
C. Whenever the battery is given an equalizing charge, an additional set of readings
should be taken and recorded as specified in Paragraph A above.
The suggested frequency of record taking is the absolute minimum to protect warranty.
For system protection and to suit local conditions or requirements, more frequent
readings (quarterly) are desirable.
*Failure to adhere to these minimum maintenance schedules will void the battery’s warranty.
