Load Bank Testing (Discharge Testing) -

This is the most comprehensive battery test and the only true examination that determines the actual capacity of the battery string.  

Load bank testing audits the batteries under both normal and peak load conditions. This demonstrates which cells hold the charge and highlights which might be approaching their end of service life. 

The Institute of Electrical and Electronics Engineers (IEEE) recommends performing discharge testing at the time of installation, then repeating the test every year. 

Testing your batteries should be of vital importance to your business as they are crutial to the continued performance of a UPS system. At Optimise Power, we offer two types of battery testing: Impedance and Load Bank Testing (Battery Discharge). Optimise Power have a number of highly skilled electrical engineers to perform installation and commissioning along with service and maintenance of most battery systems. 

Impedence Testing -

This is a non-intrusive test designed to build up a performance history of each battery cell. It is typically undertaken annually as this enables performance to be tracked over time. This makes it easier to identify any signs of deterioration or any cells with high internal impedance that might require replacing. 

Impedance testing involves applying an AC current to each battery via probes attached to the block terminals. Impedance is measured and recorded in milliohms.  

It gives a general indication of the batteries’ status without placing them under too much stress or needing to take them offline.
