Battery Maintenance & Service

In addition to the expert maintenance of electronic and power components, special care must be taken of the batteries. Weak or defective individual cells usually do not occur to the operator until they already severely affect the entire battery system. In operation, the capacity of the battery is reduced by chemical processes. This is a perfectly normal process, but has a direct impact on the autonomy time. There is a risk that the UPS system will not be completely available at the moment of a system failure (black-out). Depending on the application, this can result in serious consequences such as data loss, production losses, personal injury or property damage. Furthermore there is a risk of uncontrolled extremely high short-circuit current in the case of insufficiently maintained batteries. Since battery cells / blocks are usually the driving force behind a battery backup system, periodic maintenance and a regular capacity test are strongly recommended by us.

  • ● Battery racks and battery cells Installation
  • ● Test and record battery cell inter-cell connector resistance per IEEE- 484.
  • ● Initial battery filling and charging as recommended by the manufacturer.
  • ● Document initial charging of battery
  • ● Verify that the battery has had an equalizing charge completed more than 3 days and less than 7 days prior to the start of the test
  • ● Read and record the specific gravity and float voltage of each cell just prior to the test.
  • ● Read and record the temperature of the battery electrolyte for an average temperature (suggested every sixth cell)
  • ● Read and record the battery terminal float voltage
  • ● Disconnect the charger from the battery.
  • ● Discharge the battery at its rated current for its rated time.
  • ● Record cell voltage, and battery voltage, at the intervals specified with the load applied.
