Its intelligent design allows for automatic data storage, ensuring that your measurement results are safely and efficiently archived.
With its broad testing range, the Quicklynks meter is capable of evaluating batteries across a spectrum from 0 to 100V and 1µΩ to 200Ω. This versatility makes it an invaluable tool for professionals and hobbyists alike.
Designed for wide applicability, this versatile tester can be employed for assessing the resistance of not just disposable and varied battery types, but also extends its utility to non-battery items, making it a vital addition to any toolkit.
The Quicklynks meter is fortified with robust protections including short circuit protection, overcurrent protection, and safeguards against reverse connections. It adeptly handles both positive and negative voltages to ensure safe usage.
Powered by a substantial built-in lithium battery, this device promises long-lasting operational capability, making it ideal for prolonged projects and extensive measuring tasks.
Auto Range:
The Quicklynks meter dynamically adjusts its
range based on the internal resistance
of the object being measured, offering unparalleled
200Ω Measurement Range: Specifically calibrated for precision, the range spans from 20Ω to 200Ω, ensuring accuracy in larger resistance measurements.
2Ω Measurement Range: Tailored for moderate resistances, this range covers from 200mΩ to 2Ω, delivering precise readings for mid-range applications.
200mΩ Measurement Range: Perfect for low-resistance assessments, this range accurately measures from 20mΩ to 200mΩ, suitable for fine-tuned evaluations.
20mΩ Measurement Range: Specialized for ultra-low resistance, this range measures from an astonishing 1µΩ to 20mΩ, offering detailed insights where precision is paramount.
Voltage Range Switching:
By default, the device operates in an AUTO range mode, allowing seamless adjustments. However, users can manually switch the voltage range within
the test interface by pressing the designated key, tailoring the measurement settings to specific testing needs.

1. Does the tester come with a charger?
A: The tester is designed to be charged with a 5V power source and comes equipped with a Type-C charging cable. While a charger is not included, you can conveniently use a standard mobile phone charger.
2. Can I measure AC voltage?
A: The tester is not designed to measure AC voltage. Please avoid inputting AC voltage or DC voltage higher than 100V to ensure safe operation.
3. Does the tested battery need to be fully charged before retesting?
A: For most batteries, whether fully charged or not, the internal resistance test results remain consistent as the change in resistance is minimal. However, for a small number of battery types, a substantial power loss may affect the accuracy of the test results. In such cases, it is recommended to recharge the battery before testing.
4. Is the test result bouncing or unstable?
A: If the test results are unstable or show fluctuations, it may be due to poor contact between the test clamp and the battery, instability of the battery, the presence of an oxide layer on the electrode, or interference from a strong magnetic field nearby.
5. Can you measure large-capacity batteries?
A: Yes, the tester can measure large-capacity batteries. However, note that the internal resistance of such batteries is usually very small. Often, the resistance of the terminal connection line is higher than the battery's own resistance. Ensure that the clip is placed correctly, preferably on the original battery terminal, and maintain good contact during the test.
6. Can I test batteries without any markings?
A: This versatile tester can evaluate any type of battery, including both rechargeable and non-rechargeable varieties.
7. Why does testing the internal resistance determine whether the battery is good or bad?
A: Over time, as a battery is used, its capacity diminishes and its internal resistance increases-a natural physical phenomenon. A higher internal resistance indicates a reduced ability for current to pass through, which signifies lower battery performance. Hence, monitoring internal resistance is a reliable method to assess battery quality.
8. What is the normal internal resistance for an 18650 battery?
A: Ideally, the internal resistance should be around 20mΩ. Generally, it is about 30mΩ, and anything over 50mΩ indicates a poorer quality.
9. How much battery capacity can I test?
A: This tester is capable of testing any battery capacity, as long as the internal resistance lies within the range of 0-200Ω and the voltage is below 100V.
10. Can I test the internal resistance of a battery online? Can I test the UPS power supply?
A: Yes, in most scenarios, you can perform online testing without disconnecting the battery. This is especially applicable for UPS batteries under maintenance, which can be tested continuously.
11. What should I do if the device crashes?
A: Although no crashes have been reported, we have included a reset function. When you insert the charging cable to charge the tester, it will automatically reset itself.
