The button battery base, namely the button battery connector, is used to load the button battery, which is generally welded on the PCB board and used for power supply of the module clock. It includes a base body, positive conductive parts and negative conductive parts. The opposite edges of the base body are respectively provided with convex ribs and positioning seats to fix and limit the battery. Through the button battery holder. It can provide low-cost, highly reliable battery retention capability for various portable micro instruments, even in the case of drop, vibration or impact. Note:

1. The CMOS battery on the computer motherboard generally uses the button battery of model CR2032;
2. The installation method basically follows the same principle, that is, the positive side with letters faces upward;
3. When installing, place the positive side of the letter upward in the battery compartment and press it firmly into the compartment;
4. The flat end of the button battery is the negative pole connected to the spring, and the protruding end is the positive pole connected to the protruding end.
