Ring battery doorbells charge in 5 to 10 hours on a standard USB outlet

A Ring battery doorbell — the Ring Video Doorbell 4, Ring Video Doorbell (2nd Gen), or Ring Video Doorbell SE — takes between 5 and 10 hours to reach full charge from completely dead, depending on which model you own and the power source you use. The Ring Video Doorbell 4 is typically on the faster end of that range, while older models may take closer to 10 hours. A standard USB-A to USB-C cable plugged into any 5-volt outlet will charge the battery at the normal rate.

The time varies because Ring batteries have different capacities and the chargers deliver power at different speeds. Using a higher-amperage power adapter — one rated for 2 amps or more — can shorten charging time slightly, though Ring does not officially publish faster charging times for higher-amperage adapters. The battery itself is not user-replaceable; you remove the entire doorbell from its mounting bracket to charge it.

Key Takeaways

  • Ring battery doorbells charge fully in 5 to 10 hours using a standard USB outlet and cable.
  • The Ring Video Doorbell 4 charges faster than older models like the 2nd Gen, which may take the full 10 hours.
  • You must remove the doorbell from the wall to charge it; the battery cannot be charged while mounted.
  • A higher-amperage power adapter (2 amps or more) may reduce charging time slightly, though Ring does not may provide faster speeds.
  • The battery is built into the doorbell and cannot be removed separately.

Charging times by Ring doorbell model

Ring publishes official charging times for each model. The Ring Video Doorbell 4 charges in approximately 5 hours. The Ring Video Doorbell (2nd Gen) and Ring Video Doorbell SE both take around 5 to 10 hours, with the SE typically closer to 10 hours because it has a smaller battery capacity.

If you own an older Ring doorbell model — such as the original Ring Video Doorbell or Ring Video Doorbell Pro — check the manual that came with your device or Ring's support site for your specific model number. Charging times have improved with newer hardware, so older models may take longer than the times listed above.

What affects charging speed

The power adapter you use makes a real difference. A standard USB power adapter rated for 1 amp will charge more slowly than one rated for 2 amps or higher. Most modern phone chargers are 2 amps or more, so using a charger from a recent smartphone will charge your Ring doorbell faster than a very old or low-power adapter.

The USB cable itself also matters. A damaged or low-quality cable can reduce the power delivered to the battery. Ring recommends using the USB-C cable that came with your doorbell, or a certified USB-A to USB-C cable from a reputable manufacturer. Avoid very long cables or cables with visible damage, as these reduce charging efficiency.

Temperature affects charging as well. Charging in a cold room (below 50°F) will slow the process. Room temperature (around 70°F) is ideal for charging Ring batteries.

How to charge your Ring doorbell battery

First, turn off your doorbell using the Ring app or by flipping the breaker if your doorbell is hardwired. Then remove the doorbell from its mounting bracket by pressing the release button or unscrewing the faceplate — the exact method depends on your model. Consult your manual if you are unsure.

Locate the USB-C port on the back or bottom of the doorbell. Plug the USB-C cable into the doorbell, then plug the other end into a USB power adapter connected to a wall outlet. A light on the doorbell (usually white or blue) will indicate charging has begun. Leave the doorbell plugged in until the light turns off or changes color, which signals the battery is full.

Do not reinstall the doorbell until charging is complete. Charging while mounted to the wall is not possible and may damage the device.

Charging while hardwired versus battery-only

Some Ring doorbells can be hardwired to your home's existing doorbell wiring. If your doorbell is hardwired, it will charge slowly and continuously from the power supply while mounted on the wall. In this case, you may never need to remove it to charge manually — the battery stays topped up automatically.

If your doorbell is battery-only (not hardwired), you must remove it and charge it manually every few months, depending on how often the doorbell is used. A doorbell that records many motion events or receives frequent visitors will drain the battery faster and need charging more often. Most battery-only Ring doorbells need charging every 3 to 6 months under normal use.

Signs your battery needs charging

The Ring app will send you a notification when the battery level drops below 20 percent. At that point, you have time to plan a charging session, but the doorbell will still function. If the battery drops to zero, the doorbell will stop recording and responding to motion until you charge it again.

If your doorbell is hardwired and the battery is draining quickly despite being plugged in, the power supply may not be delivering enough current. Ring requires a transformer rated for at least 16 volts and 10 volt-amps (VA). An undersized transformer will charge the battery slowly or not at all while the doorbell is in use.

Troubleshooting slow or failed charging

If your doorbell is not charging after several hours, first check that the USB cable is fully inserted into both the doorbell and the power adapter. A loose connection is the most common reason charging appears to fail. Try a different USB cable and power adapter to rule out a faulty cable or adapter.

If the doorbell still does not charge, the battery itself may be defective. Ring batteries are covered under the manufacturer's warranty for one year from the date of purchase. Contact Ring support with your proof of purchase and the model number of your doorbell (found on the back of the device) to discuss a replacement.

Do not attempt to open the doorbell or remove the battery yourself. The battery is sealed inside the device and cannot be replaced separately.

Frequently Asked Questions

Can I charge my Ring doorbell while it is mounted on the wall?

No. You must remove the doorbell from its mounting bracket to access the USB-C charging port. Attempting to charge while mounted may damage the device or the charging port. Remove the doorbell, charge it fully, then reinstall it.

What power adapter do I need to charge a Ring doorbell?

Any USB power adapter rated for 5 volts and 1 amp or higher will work. A 2-amp adapter will charge faster. Most modern phone chargers meet these specs. Avoid very old or low-power adapters, as they may charge slowly or not at all.

Why is my Ring doorbell battery draining so fast?

High motion activity, frequent video recording, or cold weather can drain the battery quickly. If your doorbell is hardwired, a weak power supply (less than 16 volts, 10 VA) may not be charging the battery fast enough to keep up with use. Check your transformer's rating and consider upgrading if it is undersized.

How often do I need to charge my Ring doorbell?

Battery-only doorbells typically need charging every 3 to 6 months under normal use. Hardwired doorbells charge continuously and rarely need manual charging. The Ring app will notify you when the battery drops below 20 percent, giving you time to plan a charging session.

Is the Ring doorbell battery replaceable?

No. The battery is built into the doorbell and cannot be removed or replaced separately. If the battery fails, you must replace the entire doorbell unit. Ring batteries are covered under the one-year manufacturer's warranty.
