Special note : The measurement differences of this product mainly come from the fluctuation of the battery's own state, which is a normal phenomenon.

Batteries have "self discharge" and "recovery effects", and the voltage will slightly rise or fall between two measurements. The internal chemical reactions of batteries are unstable, especially for old, low battery or inferior batteries, where internal resistance and voltage fluctuations are more pronounced. Whether the battery has been used before measurement (such as just discharged) will directly affect the initial state, resulting in different data.
