Key features

• •【Powerful Battery Internal Resistance Voltage Tester】This battery tester is specially designed to measure all types of batteries, including lithium batteries, lead-acid batteries, alkaline batteries, carbon-zinc batteries, button batteries, nickel-cadmium batteries(A, AA, AAA, AAAA, C, SC, D, 9V, 3.7V 10440, 18650, CR2, CRV3, 2CR5,A13,LR621,CR2032), etc. The battery tester can be widely used for battery measurement in automobiles, motorcycles, new energy vehicles, electric cars/motorcycles, etc.
• •【Resistance/Voltage/Temp. Auto Measurement & Wide Measurement Range】The battery internal resistance tester can measure voltage and resistance at the same time. The resistance and voltage ranges are switched automatically. Our battery resistance voltage meter has a wide measurement range: 0.000mΩ~200Ω, 0.000V~±100V. Its compatibility and usage scenarios are much wider than those of ordinary battery resistance testers. It can also measure ambient temperature, range: -10~50°C (°C/°F switchable).
• •【4-wire Kelvin Test & High Accuracy】Battery internal resistance tester adopts 1KHz AC low resistance measurement technology and noise reduction technology. The universal battery tester can measure the battery in working state without disconnecting the battery. Battery internal resistance voltage meter adopts the Kelvin 4-terminal connection method to avoid the interference of wire resistance and contact resistance, greatly improving the test accuracy.The measurement accuracy is up to ±1% ±10dgt.
• •【Sorting and Comparison Function & 30 Groups of Threshold Setting Storage】Battery resistance voltage tester can be customized to set two level of resistance thresholds and a level of voltage threshold as comparison parameters. Different types of batteries have different threshold settings. The battery tester can store 30 sets of threshold settings for selection. The next test can directly select the corresponding threshold setting, which improves work efficiency and saves your time.
• •【Screen Prompt & Sound Alarm】When the resistance and voltage are compared with the set thresholds, the lithium battery tester will emit beeps of different lengths and the screen will display 'PASS', 'WARNING' or 'FAIL' to remind you the current status of the battery.
• •【HD Backlit Display & Data Hold & Data Memory】Internal resistance meter has a large high-definition backlit display, allowing you to read clearly even in dark conditions. The data hold function can lock the data, making it easier for users to read and record. The tester can automatically save the last value. If the work is interrupted, the tester will automatically display the latest value when it is restarted. So you don't have to worry about shutting down due to low battery or unexpected power outage.
