The Discharge Test for VRLA Batteries

For VRLA batteries, the annual discharge test has become the preferred method of measuring battery capacity and assessing battery condition. This remains the most accurate but also the most expensive way to check the condition of the battery and is valid only at the time of the test. The remaining battery life cannot be predicted. In recent years, improvements in VRLA battery design and the high cost of discharge testing have led many users to look for ways to reduce their maintenance regimen and related costs.

Partial Discharge: A Solution with Limitations

One of the old techniques used in place of full discharge is a partial discharge using the system load to which the battery is connected. This method has a critical issue: many failures may not be detected until the battery life limits are exceeded. In addition, a special testing system is needed on the system to perform this procedure.

New Testing Technologies: The ADELSystem

There are now testing technologies equated with manual periodic testing that allow batteries to be tested automatically and in real time. ADELSystem technology integrates this system with a testing and charging mechanism in real time, instantly providing the outcome of the system-battery status. This approach makes it possible to create an automatic maintenance program, adaptable to the conditions of the system, considering both the age and state of the battery. Such technologies, which can be implementedon low-cost devices, provide an acceptable indication of battery health status.
