Battery discharge capacity test

Batteries are used to ensure that critical electrical equipment is always on. They are used extensively and without them many of the services that we take for granted would fail and cause innumerable problems. There are three main reasons to test battery systems:

• To ensure the supported equipment is adequately backed-up
• To prevent unexpected failures by tracking the battery’s health
• To forewarn/predict death

A serious maintenance and testing program is needed, in order to ensure the batteries are in good condition, prolong their life and to find the optimal time for replacement. A maintenance program including inspection, impedance and capacity testing is the way to track the battery’s state of health. Degradation and faults will be found before they become serious and surprises can be avoided. The best testing scheme is the balance between maintenance costs and risks of losing the battery and the supported equipment.

Company “NRG source” Ltd. offers professional battery testing with TORKEL 860 device. It gives us the ability to test battery systems from 12 to 480VDC with capacity up to 3000Ah according international standards IEEE 1188*; IEEE 1106**; IEEE 450***, IS 5154-1****. Tests are carried out by trained specialist in the factory of Programma Electric AB in Sweden.

* IEEE 1188 – IEEE Recommended practice for maintenance, testing and replacement of valv-regulated lead-acid batteries for stationary applications.

** IEEE 1106 – IEEE Recommended Practice for Installation, Maintenance, Testing, and Replacement of Vented Nickel-Cadmium Batteries for Stationary Applications.

*** IEEE 450 – IEEE Recommended practice for maintenance, testing and replacement of vented lead-acid batteries for stationary applications.

**** IS 5154-1 – Lead-acid traction batteries. General Requirements and Test Methods.
