Quartz clock movement battery knowledge

I saw a quartz clock movement of Japanese Lisheng, Taiwan Sun, and Hengrong HR1688 brands. The owner said that the quartz clock cannot use alkaline batteries such as Jinbawang and Nanfu. He said that these batteries start at once and have a high current, which can easily damage the quartz clock motor. Coil. On this side, in order to sell ordinary carbon batteries in his store, is this statement based on facts? I only know that alkaline batteries have a larger capacity than ordinary carbon batteries, so the short circuit current is greater. Similarly, the discharge time is longer than that of ordinary batteries under a certain load. After a long-term experiment by netizens, it was found that generally alkaline batteries can be used on quartz clock movements.

Quartz clock movement secretly stopped repairing

The quartz clock movement often stops and leaves. It moves and leaves again. It stops after putting it back for a while. Sometimes it is caused by poor contact between the battery shrapnel and the movement circuit board. The circuit board of the quartz clock movement is connected by contact with the battery shrapnel. Due to moisture against the wall and oxidation of the contact point, over time, both methods will cause poor contact, causing the movement to be powered off and shut down. So I wanted to transform them and change the contact connection to welding connection, which will completely solve the problem of poor contact.

Specific methods: 1. Open the movement box and take out the circuit board of the movement. 2. Solder two leads on the "+" and "-" poles of the circuit board. 3. Renovation of the primary battery shrapnel: A. The two shrapnels are left one centimeter away from the part that contacts the battery, and the negative electrode is left two centimeters. Cut the rest away. B. Bend the positive electrode shrapnel at a 90-degree angle at one centimeter to snap into the movement box. C. The original right-angle bend of the negative electrode shrapnel remains and still snaps into the movement box as it is. 4. Drill a 2mm hole in the plastic plate between the movement box and the battery box to lead the negative electrode line from here. 5. Weld the two wires soldered on the movement circuit board to the positive and negative electrode shrapnel of the battery (note that the shrapnel should leave the movement box and weld it separately outside to avoid burning the movement box). 6. Replace the welded positive and negative electrode shrapnel back to its original position. After the changes, the movement was running normally and no secret stop occurred again.
