Repairing broken wall clock battery terminals
00:00 Damaged battery terminals
00:15 Open
After cleaning, open the 2 pin mechanical wall clock.
00:25 Close release
Remember the front is up, and the back is down
Prevent the gears from loosening
00:40 Clean up
connector, battery terminal
00:47 Jumper
Connect the thin wires to the new battery terminals
I'm using an old remote battery terminal
01:00 Test
Test with the battery, If the condition of the watch is good
01:22 Close the lid
And adjust the cable wire, don't block the gear part
02:25 add glue
If only necessary, prevent the battery terminals from loosening
03:11 Assemble the wall clock movement
03:21 Adjust Clock wisely 12-12
The corrosion is caused by potassium hydroxide leaking out of alkaline batteries (these are the types of batteries we put in toys, etc).
All batteries are discharged, either through use or by slowly producing hydrogen gas inside the battery.
Then applying pressure, eventually the pressure inside the battery finds its way out through the seal or as the battery ages, the seal corrodes or rusts on the outer layer.
As soon as the first signs of a leak form, it is best to throw the battery away.
But if you don't do it in time, then corrosion can continue to come out and spread out of the battery causing oxidation and corrosion of the terminals and then ruining our devices.
Do not use our fingers to remove the battery.
The potassium hydroxide chemical in the battery can irritate skin (I know because I've touched it before!).
Potassium hydroxide is a caustic substance, which is a chemical that corrodes the terminals and damages the battery.
You may also have seen tiny needle-like crystal structures, which form around the battery and terminals.
It is potassium carbonate and is formed when potassium hydroxide reacts with carbon dioxide in the air.
Repair the clock battery socket
What can be done is to solder to the CIRCLE just behind those missing battery pads.
If you can, put a new pin on the connector, get the connection there, and the battery should work again.
Along with that, we also have to solder to the other existing pads, between the connectors for the plus and minus batteries.
Repairs are delicate and delicate and require a bit of patience to do. If the loop pads aren't secure, I usually attach jumper cables to the connection points.
And the battery is directly connected to the quartz watch connector.
