1.2 Product Overview
The 3554 Battery HiTester is a measuring instrument for judging battery wear by measuring internal
resistance, voltage, and terminal temperature of lead-acid, lithium-ion and other types of batteries.
By connecting the instrument to a computer after measurement, using the included USB cable,
measurement data can be loaded to the computer.
1.3 Features
Enables measurement without shutting down UPS systems
This instrument uses high-precision AC resistance measurement technology. Since it is
capable of live-wire measurement without shutting down the UPS system, it makes it
possible to shorten the time required for measurement.
Reliable measurement values
Since it uses the four-terminal AC method to measure internal resistance, this instrument
can obtain reliable measurement values unaffected by lead or connector resistance.
Simultaneous display of resistance, voltage and temperature
Without changing functions, this instrument can display battery internal resistance, voltage
and terminal temperature simultaneously. Temperature measurement requires the optional
9460 Clip Type Lead with Temperature Sensor.
Comparator feature
Using this instrument’s comparator feature makes it possible to set threshold values for
internal resistance and for voltage, thus enabling even more reliable measurement of
battery wear.
