Spare battery for Ring doorbell plus

Hi. We have just bought a video doorbell plus and we want to buy a second battery. Not as easy as it sounds as no retailer will post a battery to the Isle of Man. We might get around that via Screwfix but before I buy I want to make sure the said battery is compatible with our Ring video door bell plus. It says the screwfix one is compatible with Ring door bell 2. Will this fit the plus please? Thank you.
