REQUIRED PERIODIC INSPECTION AND MAINTENANCE ACTIVITIES
Note:
Keep a logbook in which the measured values can be noted. Also note any power cuts, discharge tests, equalize charges, water
topping up dates, storage times and general conditions.
To obtain the full capacity and service life from your SBS stationary battery system, the performance of complete and timely periodic
maintenance is essential. Temperature extremes, improper electrolyte levels, and charging voltage imbalance are a few of the items
which can have a negative effect on the system.
Routine visual inspection, charger/rectifier checks, and pilot cell checks should be performed monthly. More detailed inspection of the
battery is required on a quarterly and annual schedule.
BATTERY ROOM AND EQUIPMENT - GENERAL INSPECTION
Perform the following checks whenever in the battery room
• The battery room is clean, dry, and clear of debris and within a 68-77ºF temperature range.
• The battery room ventilation system is operating.
• Battery room and personal safety equipment is available and operational.
• Battery cleaning and neutralization supplies are available on site.
• Battery maintenance equipment and tools are available and operational.
MONTHLY CHARGER/RECTIFIER OUTPUT CHECKS – record in a log book the following:
• Charger rectifier output voltmeter reading: It should be the same value as that read with a calibrated voltmeter. If a deviation in
voltage greater than +/- 1% occurs, the charger must be adjusted or checked for proper operation (measure voltage at battery
terminals).
MONTHLY BATTERY SYSTEM CHECKS – record in a log book the following:
• Record the battery system float charging voltage. It should be equal to the number of cells multiplied by the recommended
charging voltage per cell.
• Record each individual pilot cell charging voltage.
• Record the pilot cell electrolyte temperatures: The normal range is usually between 68-77ºF, and should have a variance no
greater than 5ºF between individual cells.
• Electrolyte levels of all cells must be between the high and low level marks on the cells: If water is added record this event.
• All cells have clean vent caps installed.
• Visually inspect each cell noting any changes or abnormalities. If anything odd is noticed, record and call sales office
immediately to determine proper action. Changes you should look for may be, but are not limited to the following: discoloration,
cracks, corrosion and growth inside or outside of container. Any noticeable sign may be a sign of trouble.
• All cells and racks are clean, dry and free of any spilled electrolyte and corrosion.
• Record room temperature.
QUARTERLY BATTERY SYSTEM CHECKS – record in a log book the following:
In addition to the monthly inspection the following checks should be completed quarterly.
• Record the charging voltage of each cell or multi-cell block in the battery system.
• Review the general condition or change in condition of the cells, racks, cables and connectors.
• Record temperature of electrolyte in pilot cells on each rack.
ANNUAL BATTERY SYSTEM CHECKS – record in a log book the following:
In addition to the quarterly inspection checks, perform the following checks annually.
Check torque of all connections, batteries and racks.
(Suggested) Record the Internal Resistance of each cell and intercell connection.
Check to ensure ventilation is okay.
