IMPEDANCE TESTER
Why assess the condition of batteries?
Secondary batteries are commonly used in UPSs (uninterruptible power supplies) and in backup power supplies for emergency power. Repeated recharging and/or extended periods of float charging of secondary batteries eventually leads to battery deterioration, evidenced by increased internal resistance and decreased capability to hold a charge. Serious problems can occur if an internal cell develops a short circuit, causing low voltage and potential overheating that can result in a fire. With our new BATTERY HiTESTER 3554, you can be assured of a quick and accurate diagnosis of deterioration by measuring the internal resistance and terminal voltage of backup type batteries in the field, without having to disconnect or shut down the system.
The four-range design covering 0.001 mΩ to 3.100Ω enables easy measurement of the mid- and high-capacity batteries in these devices. By simply specifying primary and secondary limits for the battery resistance and the minimum voltage threshold, the battery tester quickly displays Pass, Warning or Fail based on the combination of reference values, for fast and accurate assessment
