Always good to have an extra battery available for the Ring doorcam. Not sure why Ring didn't just charge a bit more and have two batteries included in with the doorcam since it takes about 10 hours to charge the battery (meaning downtime in security footage during the charging process). Needless to say, this replacement battery fits the bill. A bit on the pricey side but at least you can do a battery swap out with minimal downtime. Would like to have seen these batteries a bit less expensive as I'm sure they will need to be replaced out eventually as well. Overall a decent replacement for the OEM battery pack.
