Portable Internal Resistance Meter for Lithium batteries

It is a high-precision internal resistance meter for rechargeable batteries, capable of measuring battery voltage and internal resistance of AA, AAA, and 18650 batteries. The tester gives the most accurate readings with 1% accuracy based on the 4-wire battery measurement arrangement.The device includes a rechargeable battery and a Type-C interface; it can be charged with any 5V charger. In the event of a power outage, LO is displayed on the LCD for 1 second. The button above the display is used to turn on or off the backlight. A 3-second long press will switch off the gadget. The device also has a sleep mode, which means that if no operation is detected, the device will go into sleep mode after 30 seconds. If the voltage or internal resistance of the tested battery is zero, this could be the result of inadequate connecting. Please replace the battery and remeasure it.
