Skybell ADC-VDB105 battery

My door bell (Skybell Slim Line ADC-VDB105) stopped working. The battery swelled up and needs replacement.

I can’t find a matching battery anywhere. The battery connector is 3-wire and the battery has “PT412532-2” marking.

Can someone help me to locate a replacement battery please?

Alarm.com does not officially have a replacement battery. You may be able to reach out to SkyBell as they are the manufacturer but I have never seen the battery for the slim for sale.

There should be voltage and mAh ratings on the battery to possibly find a replacement online.
