You only need one battery for your Ring Video Doorbell 4 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 4 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 4 battery
- Unscrew the faceplate from the doorbell and remove the faceplate by pressing in on the sides and carefully pulling it out and off.
- Remove the battery by pressing the release tab.
- Connect the micro-USB charger to the battery's charging port. During charging, both the red and green lights will illuminate. Your battery is fully charged when the light on it shines a solid green.
- Slide the fully charged battery back into the doorbell until it clicks in place.
- Place the faceplate back on by slotting it in at the top and clicking it into place.
- Your doorbell will power up and be ready for use.
If my Ring Video Doorbell 4 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. If you don't want to experience downtime while charging the battery, you can purchase a second battery on Ring.com.
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 4 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.
