Midronics announced the availability of an innovative solution for critical power reliability with the release of its CellGuard ELS+ electrolyte level monitoring system. This customer-driven product assures reliable 24/7 monitoring of VLA (vented lead-acid) battery electrolyte levels and is easily integrated into a battery management system for VLA battery maintenance. The ELS+ monitoring system is commonly used in reserve power applications for backup power in utilities, telecom and grid energy storage.
Strict monitoring is essential for VLA batteries to ensure optimal performance and a long operating life. VLA batteries (also called flooded batteries) continuously deplete their electrolyte by outgassing hydrogen and oxygen. Distilled water must be added to the battery as part of its maintenance. The lead plates inside the battery must be fully immersed in electrolyte in order to operate at optimal level. Once gassing occurs and plates are exposed, they become inactive, reducing battery capacity.
The CellGuard system is simple to install, and is completely non-invasive to the battery. It saves time and money by eliminating the need for manual inspection. ELS+ enhances safety by reducing the frequency of close contact with batteries and battery acid, in additional to providing alarming when battery case temperatures reach abnormal levels.
