18650 cylindrica battery holder means 18 mm in diameter and 650 mm in length. The model of No. 5 battery is 14500, with a diameter of 14mm and a length of 500mm. Generally, 18650 batteries are used more in industry and less in civil use. Common batteries are used more in notebook batteries and high-grade flashlight. 18650 is only the size and model of the battery. According to the type of battery, it can be divided into 18650 of lithium ion, 18650 of lithium iron phosphate and 18650 of nickel hydrogen (very rare). At present, the common 18650 is lithium ion.

Button battery base is used to load button battery, which is generally welded on PCB board to facilitate button battery power supply module clock or other consumer electronic products.
Installation method of battery base
There are two installation methods of button battery base, one is plug-in type and the other is patch type.
Suggestions for battery base selection:
Installation aging;
Dimensional accuracy and drape;
Button battery is the key component in many micro instruments;
The cost of button battery base is generally plastic materials such as LCP, PPS and PBT, metal shrapnel materials such as iron, steel and copper (metal shrapnel electroplating treatment such as nickel, tin and gold). There are differences in temperature resistance, corrosion resistance, drop, conductive stability and exquisite appearance of different materials;
If there are requirements for PCB space, battery shrapnel (pure hardware) can be selected, but the positive and negative of battery shrapnel are divided into two parts separately, and one step is added to the assembly. For example, for individual remote controls, positive battery shrapnel, negative shrapnel or gold, nickel and tin sinking process can be used.

How to identify the positive and negative poles of button battery base
Generally, the button battery marked with "+" is the positive pole, and the back is the negative pole; The shell at the edge of the button battery is also positive, so most button batteries loaded on the button battery base are positive upward, because there are metal shrapnel at the side end of the button battery base to prevent the button battery from falling out. This is the positive electrode metal shrapnel, which will cling to the positive electrode edge of the button battery. Due to the large-area electrode contact of the positive electrode metal shrapnel, Effectively improve the stability of electrode contact; If the positive and negative poles of the button battery are replaced, the battery can also be stuck, but the battery will be short circuited.
How to remove the battery from the button battery holder
The accessories with button battery base on the product are easy to replace the old and new button batteries. The metal shrapnel can be moved easily. If you look carefully, you can find the method to take out the button battery. Some button battery base designs may need a small insulating plastic sheet to assist in taking out the button battery.
Plug in type
The button battery base cannot be welded with tin;
Add flux to reduce surface tension and improve wettability;
Increase welding temperature;
Replace the solder paste.
