Battery tester

A battery tester is complex testing hardware for measuring battery life and performance during lifecycles. The main commercial parameter is the inside whether the analyzed device has claimed battery capacity.

This test is carried out to analyze the parameters of the battery installed in the device and its reaction during different current loads. Based on the test results, it is possible to make conclusions about the quality of the battery and its compliance with its declared parameters.

Description of the battery tester device

A battery tester is a laboratory-made device for making the battery device’s test almost in automatic mode. An expert just needs to place the battery in the special grip on the device and then the device itself makes contact with it and conducts the test.

The device is fully customizable to individual test parameters: the load fork is 100% configurable by connecting to a computer and setting parameters via a simple user-friendly algorithm.

A memory mode is available on the unit, making it easy to set test parameters and shorten test times. The unit supports testing of the following types of batteries: NiMH (nickel-metal hybrid), NiCd (nickel-cadmium), LiPo (lithium-polymer), LiFe (lithium-iron-phosphorus), and Pb (lead) batteries.

Automatic tester mode supports automatic round-robin charge-charge tests, recommended for capacity check Measure Modes Voltage measurement 0 – 4.5 V, accuracy 0.003 V, accuracy ± 0.5% 4.5 – 30 V, accurate to 0.01 V, ± 0.5%.

Current measurement 0.05 – 10.00 A, accuracy 0.005 A, error ± 0.5% Capacity measurement < 10 A, resolution 0,001 Ah 10 Ah – 100 Ah, resolution from 0,01 Ah > 100 Ah, resolution 0.1 Ah.

The device has 4 lines: voltage and current channels separated for high test accuracy; LCD display: voltage, current, time, capacity; PC connection: the tester can connect to a computer through a designated USB-TTL cable for more functions, like graphs, calibration, firmware upgrade, and test circulation.


– simple plug-and-play operation;
– direct AC power connection ensures 100% uptime during battery-out service with no need to charge unit;
– provides a regulated voltage, ensuring safe operation while converting 120 VAC to 14VDC;
– parasitic Draw Indicator;
– easy to read LED indicators show low, medium, or high current draw aiding in diagnosis;
– solid Green or Yellow Lights indicate that current is in the normal range;
– solid Red Light indicates that current is in the high range;
– option of battery test’s parameters memory;
– user-friendly interface during the connection to PC for making graphics, test calibration, firmware upgrade, and test circulation.
