Sealed batteries are sensitive to temperature and float voltage settings.
Monitoring these conditions can considerably extend useful battery life.
A Liebert battery monitor provides the user with detailed information, allowing for cost savings by optimizing useful
battery life. Instead of waiting for an inevitable failure or replacing batteries prematurely to prevent problems, you
can continue to utilize your batteries longer and with condence by knowing their true internal condition.
It is essential to detect deterioration at an early stage to prevent catastrophic failures when dealing with sealed
batteries. This makes measurement technology the most important consideration when selecting a monitoring
system. Other battery monitors’ internal ohmic readings become inconsistent as the UPS load varies because of
variations in AC ripple on the battery. The Albér DC resistance test method is not inuenced by ripple and thus
provides data that is repeatable and reects the true condition of the battery.
