Charging your Ring doorbell battery takes 5 to 10 hours with a USB cable

Your Ring doorbell battery charges through a micro-USB port on the device itself — the same type of cable that charges many phones and tablets. You do not need to remove the battery or take the doorbell off your wall. Plug the cable into the port, connect it to any USB power source (a wall adapter, computer, or power bank), and the battery charges while the doorbell stays in place and keeps working.

The battery inside a Ring doorbell is not user-replaceable, so charging is the only way to restore power. Most Ring doorbells hold a charge for several months if motion detection is off, or a few weeks if motion detection is on and your doorbell sees regular activity. How often you charge depends on how many people walk past your door and how many times the doorbell records video.

Key Takeaways

  • Ring doorbell batteries charge through a micro-USB port on the device using any standard USB power adapter or cable.
  • A full charge takes 5 to 10 hours, and the doorbell continues to work while charging.
  • The battery lasts several months without motion detection, or a few weeks with motion detection on and regular activity.
  • If your doorbell is hardwired to your home's electrical system, it charges automatically and you will rarely need to plug it in manually.

Locate the micro-USB port on your Ring doorbell

The micro-USB port is a small rectangular opening on the side or bottom of your Ring doorbell, depending on which model you own. On the Ring Video Doorbell (2nd Gen and newer), the port is on the bottom. On the Ring Video Doorbell Pro, it is on the side. Look for a small slot about the size of a grain of rice — it sits next to or near the speaker grille.

If you cannot find the port, check the manual that came with your doorbell or look at the Ring app on your phone. Open the Ring app, tap the menu icon, select your doorbell, and go to Device Settings. The Device Health section often shows a photo of your specific model with the port labeled.

Use the correct USB cable and power source

You need a micro-USB cable — the same cable that charges many Android phones, older tablets, and other small electronics. If you do not have one, they cost $5 to $15 at any electronics store or online retailer. Do not use a USB-C cable or a Lightning cable, as these will not fit the port.

Plug the other end of the cable into any USB power source: a wall adapter (the kind you plug into an outlet), a computer USB port, a laptop, or a USB power bank. The power source does not need to be Ring-branded or special in any way. A standard 1-amp adapter works fine, though a 2-amp adapter charges slightly faster. Avoid very old or damaged cables, as these can charge slowly or not at all.

Charging time and what to expect

A completely dead Ring doorbell battery takes 5 to 10 hours to charge fully, depending on the power source you use. A wall adapter charges faster than a computer USB port. While the battery charges, your doorbell continues to work — it will still record video, send notifications, and let you talk through the speaker. You do not have to unplug it or wait for charging to finish before using it.

The Ring app does not show a battery percentage while charging, so you cannot watch the progress in real time. Once the battery reaches full charge, the app will show "Excellent" or "Good" in the Device Health section. If the app still shows "Low" after 10 hours of charging, the cable or power source may be faulty — try a different cable or outlet.

Hardwired doorbells charge automatically

If your Ring doorbell is hardwired to your home's existing doorbell wiring, it charges automatically whenever power flows through those wires. You will not need to plug in a USB cable at all. Hardwired doorbells have a small transformer connected to your electrical panel that keeps the battery topped up continuously.

To know if your doorbell is hardwired, look behind the doorbell at your front door. If you see two thin wires connected to the back, it is hardwired. If there are no wires, it is battery-only and you will need to charge it manually every few months. Some Ring doorbells can work either way — hardwired or battery-only — depending on how you set them up during installation.

Troubleshooting a doorbell that will not charge

If your Ring doorbell does not charge after 10 hours, first try a different USB cable. Cables wear out or break, and a damaged cable is the most common reason charging fails. If you do not have another cable, borrow one from a phone or tablet to test.

Next, try a different power source. Plug the cable into a different wall outlet, a computer, or a power bank. Some outlets are controlled by a switch and may be turned off. Some USB ports on older computers do not provide enough power. If the doorbell charges with a different outlet or power source, the original one is the problem.

If the doorbell still will not charge with multiple cables and power sources, the micro-USB port itself may be damaged, or the battery may have failed. Contact Ring support through the Ring app — tap the menu, select your doorbell, scroll to the bottom, and tap "Get Help." Ring will ask you to describe the problem and may send you a replacement device.

How to extend battery life between charges

Turn off motion detection if you do not need it. Motion detection drains the battery much faster than simple recording. In the Ring app, go to your doorbell settings, find Motion Detection or Motion Alerts, and toggle it off. Your doorbell will still record when someone presses the button, but it will not record every time a car or person passes by.

Lower the video quality if your doorbell allows it. Higher resolution uses more power. In the Ring app, go to Device Settings and look for Video Settings or Resolution. Lowering it from 1080p to 720p extends battery life noticeably. You can also reduce the length of video clips — shorter clips use less power to record and store.

Charge your doorbell before the battery gets completely empty. A battery that sits dead for weeks may not charge properly. If you notice the app shows "Low" battery, plug in the USB cable that week rather than waiting until the doorbell stops working.

Frequently Asked Questions

Can I charge my Ring doorbell while it is raining?

No. The micro-USB port is not waterproof, so water can enter the port and damage the electronics inside. If your doorbell is outside and it is raining, wait for dry weather before charging. If you must charge during wet weather, use a small cover or awning to shield the port from direct water.

Does the Ring doorbell come with a USB cable?

Most Ring doorbells do not include a micro-USB cable in the box. You will need to buy one separately, or use a cable from another device. Ring sells official cables on their website, but any standard micro-USB cable works just as well and costs less.

What happens if I leave the USB cable plugged in after the battery is full?

Nothing bad happens. Once the battery is fully charged, it stops accepting power. Leaving the cable plugged in does not overcharge the battery or damage it. You can leave it connected indefinitely without risk, though there is no benefit to doing so.

Why does my Ring doorbell battery drain so fast?

Motion detection is the main reason. If your doorbell is in a busy area with lots of foot traffic or passing cars, motion detection records constantly and drains the battery in weeks instead of months. Turning off motion detection or lowering the sensitivity extends battery life significantly. Cold weather also drains batteries faster than warm weather.

Can I use a fast charger or power bank with my Ring doorbell?

Yes. Ring doorbells work with any USB power source, including fast chargers and power banks. A faster charger will not damage the doorbell — it will simply charge the battery at the speed the doorbell can accept, which is the same whether you use a 1-amp or 3-amp adapter.
