You only need one battery for your Ring Video Doorbell 2 to work properly. However, if you want extended battery life or don't want to experience any downtime while charging the battery, a second battery is available for purchase.
Use a common micro-USB cable, such as the orange one included in your Ring box. Simply plug it into any USB power source. Your Ring Video Doorbell 2 battery can take around 5-10 hours to fully charge depending on whether the USB cable is plugged into a USB port or a wall outlet.
How to charge your Ring Video Doorbell 2 battery
- Remove the security screw on the base of the doorbell and lift the faceplate up and away from the wall.
- Remove the battery by pressing the release tab.
- Connect any micro-USB charger to the charging port in the battery. Both lights will illuminate when the battery is charging. When only the green light remains on, your battery is fully charged.
- Slide the fully charged battery back into the doorbell. There will be a click when the battery is secure.
- After about 30 seconds (during which your doorbell will start up again), return the faceplate to the doorbell and secure it with the security screw.
If my Ring Video Doorbell 2 is hardwired, does it still need a battery?
Yes, your device will get a trickle charge from the wiring, but it still requires a battery.
My battery is hardwired to my existing doorbell or connected to a solar charger. But according to the Ring app, my charge keeps falling to 90%. Why is this happening?
The trickle charge your Ring Video Doorbell 2 gets from being hardwired or solar charged is only used to charge the battery – not run its operations. To maximize the battery's overall lifespan, your doorbell waits for its charge to fall below 90% before using wired or solar power to recharge it.
