11.3 Maintenance Records
A complete recorded history of the battery operation is essential for obtaining satisfactory
performance. Good records will show when corrective action may be required to eliminate
possible charging, maintenance or environmental problems.
Should you have ANY questions concerning how to perform the required maintenance, contact
your nearest EnerSys
® sales/service representative or call the corporate office number listed on
the back of this manual and ask for EnerSys Reserve Power Service.
Accumulate and permanently record the following data for review by supervisory personnel so
that any necessary remedial action may be taken:
1. Upon completion of the initial charge and with the battery on float charge at the
proper voltage for one (1) week, read and record the following:
• individual cell or unit voltages (volts)
• cell-to-cell connection resistance (ohms)
• terminal connection resistance (ohms)
• ambient temperature in the immediate battery environment (˚F or ˚C)
2. Every 12 months, read and record the following:
• individual cell or unit voltages (volts)
• cell-to-cell connection resistance (ohms)
• terminal connection resistance (ohms)
• ambient temperature in the immediate battery environment (˚F or ˚C)
Any connection resistance that exceeds the base value by more than 20% should be corrected
by the procedures of Section 11.
3. If corrosion is present in the connections, clean according to Section 11.1.
4. Whenever the battery is given an equalizing charge, an additional set of readings
should be taken and recorded.
THE ABOVE FREQUENCY OF RECORD TAKING IS THE ABSOLUTE MINIMUM TO PROTECT THE
WARRANTY. This data will be required for any warranty claim made on the battery. For system
protection and to suit local conditions/requirements, more frequent readings (quarterly) are desirable.
Sample record charts are provided on the following pages. Make a copy of the chart to use for your
permanent records.
NOTE: Some internal failure modes of cell types DDm, mSeries, DDS, DDV, and DGX cannot be
detected by cell or unit voltage measurements. IEEE-1188,1996 recommends taking an
internal ohmic measurement of the cell/unit at quarterly intervals. These internal ohmic
measurements, when compared with baseline value or the average value, may indicate the
beginning of a problem inside the cell. Then corrective actions can be taken to avoid
a battery system failure. EnerSys
® recommends that you follow IEEE-1188 standards for
internal ohmic measurements for VRLA cell types.
