• Extremely Simple Operation: Testing is completed in just three steps with no complex setup required, significantly lowering the barrier to use and improving the user experience.

Product Cons

• Cannot Test Very Low Voltage Batteries: If the tested battery's voltage is below the startup threshold, the device will not display a reading, making it unable to assess the state of completely depleted batteries.
• Limited High-Precision Measurement: The product is unsuitable for scenarios requiring extremely high voltage measurement precision beyond one decimal place and cannot replace professional-grade electrical equipment.
• Contact Issues with Some Non-Standard Batteries: Some user feedback indicates that specific brands or sizes of non-standard batteries (e.g., 123 type) might experience poor contact due to labels or other factors, requiring manual adjustment.
• Non-Universal Battery Type Compatibility: Cannot test all special battery types, such as 18650 flashlight batteries, limiting its application scope in professional fields.
