SmaTrig 2.1 battery

I want to attach solar battery power unit on it. Changing battery is pain. The builder said it will last few years with one coin battery. The battery is a size of 25 cent coin with 3-4mm thickness. 3 Volts and CR 2032 is written on top.

I damaged one of plug’s sleeve. Is there a special tool to remove or tight plug ring?
