There doesn’t seem to be an aftermarket part for this. Just search for cell socket for whatever the battery size is. Such as 2032 battery socket and what not. All you need is a soldering iron and some new solder to install the new one. You don't seem to realize that this is not a coin cell battery. q4hbUy.
