Hioki portable battery testers support the maintenance of UPS and storage batteries critical to the life support of all businesses. The 3554 sets the standard for assessing the deterioration and remaining life of lead-acid batteries by giving a complete diagnosis via battery resistance testing.
Note: The thresholds for determining the pass/fail condition of a battery depends on the specifications and standards of the battery manufacturer, battery type, capacity, etc. It is important and necessary to always conduct battery testing against the internal resistance and terminal voltage of a new or reference battery. In some cases, it may be diffcult to determine the deterioration state of traditional open type (liquid) lead-acid or alkaline batteries which demonstrate smaller changes in internal resistance than sealed lead acid batteries.
• Instantaneously diagnose degradation (PASS, CAUTION FAIL) by measuring internal resistance and voltage
• Increased measurement efficiency thanks to new compact, lightweight probes
• Store up to 4,800 data points in built-in memory and transfer to PC via USB
