I have a small pendullum wall clock. The battery component is no good. Batteries erroded and wires got detached. Can that be replaced or repaired. I have sautering materials just not sure where the wires belong.

Question edited for clarity, and add MAKER, so few words, so many spelling mistakes!

Lithium batteries aren't rechargeable. Your small round CR2032 battery lasts 8 years. It is the same battery in a computer motherboard and easy to find in any pharmacy.

REPLACING 3V LITHIUM BATTERY The Auto-set time memory is maintained by a lithium button cell battery, model CR2032. The expected life of this battery is about 8 years. Be sure that the 2 "AA" batteries in the clock are fresh. The MODE switch (8) must be in the RUN position when replacing this button cell battery. This battery is located in the small round battery compartment on the rear of the clock secured by a screw. Open the battery compartment (3) with a screw driver and replace the CR2032 lithium battery observing the polarity. Then close the compartment securing with the screw.

Check for loose wires between the clock Movement and the chime box. If those are good (and the batteries have good solid connection-not lose) you probably need to replace the chime control box or the whole movement.
Timesavers.com carries replacements.
Mechanical clocks, while more in cost, will live a much longer life with proper care than battery clocks. Plus, an actual chime (not noise through a speaker) is much more pleasing to the ears.

Good details! Go to Timesavers.com
You can find a replacement pendulum unit there. Your pendulum mechanism probably has a bad coil. The coil is extremely difficult to repair.

hello lucy... you most likely have some corrosion in the outdoor component. Remove the batteries from the outdoor component and clean the battery contacts with the eraser end of a common pencil. Reinstall the batteries and then give it up to 8 hours to start reporting accurately again. Joe

Thanks for choosing Fixya!

I had one of these a while back and it had a required sequence for putting in the batteries. When the signal dies and you have to replace the transmitter batteries and the clock batteries in a certain sequence. The transmitter batteries cannot just be replaced. You also had to remove the clock batteries, then put in the transmitter batteries, then replace the clock batteries.

mcdevito75 here, I'd bring the clock to a small watch repair shop in the area and have them look at it.

Simple, the instructions state that when changing the batteries on the outside temp. sensor, you must also change the batteries on the main clock unit. I had same problem when I changed the sensor batteries until I pulled the batteries from the clock and it reset fine. ( Sensor batteries first, then clock batteries. ) The clock will reset to atomic time overnight so don't worry if it doesn't read correctly at first.

After replacing the transmitter batteries several times, I tried replacing the clock batteries. They must have been getting low. Once I put in new batteries in the clock it worked fine. Good Luck.
