Problems solved by technology

[0005] When the battery is low or dead, there may be abnormalities such as unable to set the power-on password, unable to save the BIOS settings, abnormal system time when starting up, no display when starting up, unable to start normally, and the system automatically restarts, etc., which seriously affect the normal use of the user.
[0006] In the prior art, before the battery is installed in the server, the power of the battery is not detected. When the power of the battery cell is insufficient, the server cannot work normally. This is the deficiency of the prior art.

Embodiment Construction

[0021] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0022] Such as figure 1 As shown, according to the corresponding relationship between CR2032 battery storage temperature and time, when the battery is stored in the warehouse after incoming materials, its temperature is controlled at 0°C~30°C, and the relative humidity RH (Relative Humidity) is controlled at 40%~75%, 21°C for the best.

[0023] Such as figure 2 As shown, there is a certain curve characteristic between the voltage and the power of the lithium-manganese button battery CR2032. When the CR2032 battery will drop significantly at both ends, it will slowly drop from the nominal voltage of 3V to 2.9V at the beginning, and the middle 2.9V will maintain for a long time. When it is lower than 2.9V,...

Abstract

The invention relates to a test method for single lithium-manganese button cells. The method is characterized by comprising the following steps: (1) putting a to-be-tested lithium-manganese button cell in an environment of 0-30 DEG C to keep the temperature of the to-be-tested lithium-manganese button cell at 0-30 DEG C; (2) putting the to-be-tested lithium-manganese button cell in an environment of which the relative humidity is 40-75% to keep the relative humidity of the to-be-tested lithium-manganese button cell at 40-75%; and (3) measuring the voltage of the to-be-tested lithium-manganese button cell, judging that the to-be-tested lithium-manganese button cell is qualified if the voltage of the to-be-tested lithium-manganese button cell is greater than or equal to 2.9 V, or, judging that the to-be-tested lithium-manganese button cell is unqualified.

Description

technical field [0001] The invention belongs to the technical field of battery detection, and in particular relates to a detection method for lithium-manganese button battery cells. Background technique [0002] Lithium-manganese button battery refers to a battery whose material is lithium manganese dioxide and whose shape is like a small button. The non-rechargeable CR series is commonly used on server motherboards, the model is CR2032, and its naming is based on the IEC (International Electrotechnical Commission) standard, where C- is a chemical battery system with lithium metal as the negative electrode and manganese dioxide as the positive electrode. R- indicates that the shape of the battery is cylindrical, 20 indicates that the diameter of the battery is 20mm, 32 indicates that the height of the battery is 3.2mm, the nominal voltage is 3.0V, the end point voltage (End Point Voltage) is 2.0V, and the rated capacity is 200- 230mAh varies. [0003] Its appearance is mad...
