- For use with compact batteries such as NiCad and nickel-metal hydride
- Instantaneously diagnose degradation (PASS, CAUTION, FAIL) by measuring internal resistance and voltage
- Operator must input the criteria for PASS/FAIL judgments according to the type of battery being measured.
On-the-spot testing of compact storage batteries - portable telephones and similar applications
The Hioki 3555 is a 300 mohm to 30 ohm/30V portable battery internal resistance tester suitable for testing high-capacity alkaline and lead-acid storage batteries used in mobile devices. With improvements in battery technology, the range of applications in portable devices is growing rapidly: not only mobile phones, but also video cameras, laptop computers, and other electronic devices. But the performance of these devices depends on the lifetime and performance of the batteries. Because of the wide variation in battery lifetime depending on the charging frequency and pattern of use, battery maintenance tools are indispensable.
The 3555 BATTERY HiTESTER provides a simple, on-the-spot assessment of the state of compact storage batteries, including nicad (Ni-Cd) and nickel metal hydride (Ni-MH) batteries.
Simultaneously measure resistance and voltage
The Hioki 3555 uses the same AC four-terminal method as that used on Models 3550 and 3551 for testing lead-acid batteries to measure the internal resistance, and simultaneously measures the battery voltage, to give an immediate Pass/Warning/Fail result.
The AC four-terminal method supplies an AC current from the source terminals to the battery being tested and measures the voltage drop with the sense terminals. This cancels out the contact resistance and lead resistance, and provides accurate measurement of low resistances.
Three-rank rating of battery state: Pass, Warning, or Fail
The Pass/Warning/Fail assessment of a battery's state is based on a six-way combination of comparisons against upper and lower resistance limits and a voltage threshold. This result is then indicated by LEDs and a beeper. The comparison threshold values depend on the battery manufacturer, type, and capacity, and these must be established by the user.
Once the appropriate comparison values for the battery being tested have been entered or recalled from memory, measurement is as simple as touching the pin-type probes to the battery terminals. Since the tester is battery-operated, it can also be used anywhere.
Once a compact storage battery, typically one used in a mobile phone, exceeds the manufacturer's guaranteed limit on charge-discharge cycles, its charging capacity gradually deteriorates, and the operating time on a single charge may become extremely short. A simple test is therefore required to determine whether an apparently faulty device simply has a failing battery. In cases such as these, the 3555 BATTERY HiTESTER gives exactly the guidance needed to determine whether or not to replace the battery.
