I appreciated that you shared this! Do you mind sharing what glue you use to put it back together? Do you have battery recommendation? I purchased this 3v battery from amazon: https://www.amazon.com/dp/B09CLGNQP7?psc... (2CR17335A) for $20.98. I'm not sure if it works yet -- still need to do the soldering. I plan to unsolder the wire from the previous battery and solder it to the new one (the connector to the system board is different).
