Blog / Based on Maintenance & Effectiveness


For VRLA batteries, the annual discharge test initially became the preferred method for measuring battery capacity and for assessing its condition. This remains the most accurate, but also the most expensive, way to check the battery condition and is valid only at the time of testing.

The battery life: can be predicted? No. In recent years, improvements in the design of the VRLA battery and the high cost of discharge tests have led many users to look for ways to reduce their maintenance regime and cost. One of the old techniques used in place of full discharge was a partial discharge using site load. 
This method has the main weakness about faults that may still not be detected until the accepted battery exceeds life limits. A local test system is also necessary.  

Thanks to today's technologies, there is the availability of better options for current practice for the same battery test year after year to check the condition of the batteries, and it is in real-time 

FFor example, Adelsystem has a specific internal check batteries system, which does not require external systems.  Tests are best suited to the age and the current condition of the battery. A condition-based maintenance program uses this modality.


This event would typically involve regular low-cost techniques that provide an indication of the health of the battery at the beginning of its life cycle.
