Sadly, I didn't took any picture or video during the process. :<

Also, I didn't drill the RTC. I use electric angle grinder with metal cutter wheel to *slowly* scrape off the epoxy on the RTC, with locking pliers to hold the RTC securely in place.

Ideally, you could use Dremel with appropriate wheel to do it, but I have to do it with what tool I have.

Be mind that you must not cut the metal strip that gone on top of battery off completely, as it the minus (-) lead that you need to solder a wire to the replacement CR2032 battery socket. It would be a pain to solder that tiny spot on hard to solder metal. See the "metal strip that gone on top of battery" picture on the last picture of this post https://forums.irixnet.org/thread-2488-p...l#pid17625

The hardest part would be removing the old battery. There is 2 option. (if you can think of more option, feel free to add it)

- One is completely remove the old battery but it would be complicated to not destroy the metal strip that connect to the bottom of battery (plus (+) lead), it hard but could be done with more epoxy scraping around the battery.

- Two is destroy the battery and leave it's casing on the Dallas. This is easier, but *you have to know what your doing as it more dangerous due to risk of toxic fume and explosion from battery*. I use this method as it more easier for me to solder the plus (+) lead on to side of old battery casing.

Starting off by wearing toxic fume protective mask and eyes protection glasses, gently drill or use electric angle grinder to cut a small hole on top of battery, there may be chemical burn come out of the hole, wait for it to sattle down.

Then use a pliers to rip off the top cap of battery and clean the electrolyte off the battery casing.

After this, sand the battery casing and "metal strip that gone on top of battery" for it to easier for solder to stick to the surface, then solder the small wire and CR2032 battery socket.

Use Cyanoacrylate adhesive (aka. super glue) to glue the battery socket on top of the Dallas and maybe drop it on the solder joint on the Dallas to prevent rust.
