Ring doorbell batteries charge in 5 to 10 hours with a standard USB charger

A Ring battery — the rechargeable pack inside Ring video doorbells and cameras — takes roughly 5 to 10 hours to charge fully, depending on which Ring model you own and what charger you use. The exact time varies because Ring makes several battery types across different product lines, and a faster charger cuts the time down.

Most Ring devices ship with a USB charging cable. If you use the cable that came in the box with a standard 5-watt phone charger, expect the longer end of that range. If you plug into a faster charger — anything rated 2 amps or higher — you can shorten it to the lower end. The battery itself holds enough charge to power a Ring doorbell for months between charges, depending on how much motion and activity it records.

Key Takeaways

  • Ring batteries charge in 5 to 10 hours using the included USB cable and a standard phone charger.
  • A faster charger (2 amps or higher) cuts charging time closer to 5 hours instead of 10.
  • Different Ring models use different battery types, so check your device manual for the exact specifications for your model.
  • The battery drains faster if your Ring records frequently or if you live in a cold climate, so you may need to charge it more often.

What affects how fast your Ring battery charges

The charger you use makes the biggest difference. Ring batteries are lithium-ion packs that accept a range of charging speeds. A weak charger — like an old 500-milliamp phone charger — will take the full 10 hours or longer. A modern phone charger rated for 2 amps (2000 milliamps) can cut that time nearly in half. You do not need anything exotic; any USB charger you already own that outputs 2 amps or more will work.

Temperature also matters. Lithium-ion batteries charge more slowly in cold weather. If you live somewhere that gets below 50 degrees Fahrenheit, or if you leave your Ring outside during winter, charging will take longer. Extremely cold temperatures can also prevent the battery from charging at all until it warms up. Room temperature (around 70 degrees) is ideal.

The battery's current charge level affects speed too. A battery that is completely dead charges fastest in the first half of the cycle, then slows down as it approaches full capacity. This is normal behavior for lithium-ion batteries and protects their lifespan.

How to know when your Ring battery is fully charged

The Ring app on your phone shows the battery percentage in real time. Open the app, go to your device, and look for the battery indicator — it displays as a percentage or a battery icon. When it reaches 100 percent, the battery is fully charged and you can disconnect the cable.

Some Ring models also have a light on the device itself that changes color during charging. Check your device manual to see what the light means for your specific model. Once the light stops changing or turns a steady color, the battery is done charging.

Why your Ring battery drains faster than expected

Motion recording is the biggest drain. Every time your Ring detects motion and records video, it uses battery power. If you live on a busy street, have frequent deliveries, or have pets that trigger the motion sensor, your battery will drain much faster than someone in a quiet area. You can extend battery life by adjusting motion zones in the Ring app to ignore areas where you do not care about recording.

Live view also drains the battery. Each time you open the Ring app and watch the live video feed, you are drawing power. Frequent live view checking can noticeably shorten the time between charges.

Cold weather drains batteries faster than warm weather, even when the device is not actively recording. Lithium-ion batteries lose capacity in cold temperatures, so a Ring doorbell in Minnesota will need charging more often than one in Florida.

Poor WiFi signal forces the device to work harder to stay connected, which drains the battery faster. If your Ring is far from your router or has a weak signal, moving the router closer or adding a WiFi extender can help.

Charging your Ring battery without removing it

Some Ring models allow you to charge the battery while it stays installed in the doorbell. Ring Video Doorbell (2nd and 3rd generation) and Ring Video Doorbell Pro models have this feature. You straightforward plug the USB cable into the charging port on the device itself, and the battery charges in place.

Other models, like the Ring Video Doorbell Wired, do not have a removable battery at all — they draw power directly from your home's existing doorbell wiring. If you have a wired model, you do not need to charge anything.

Check your device manual or the Ring website to see whether your specific model has a removable battery and whether it can charge in place. If you are unsure, the safest approach is to remove the battery and charge it separately using the included cable.

How often you need to recharge your Ring battery

In typical use, most Ring batteries last 2 to 3 months between charges. "Typical use" means a doorbell that records a few times per day — a few deliveries, some passing traffic, maybe a neighbor walking by. If your Ring records constantly or you live in a very cold climate, you might need to charge it every 4 to 8 weeks instead.

The Ring app will send you a notification when the battery drops below 20 percent, giving you time to charge before it dies completely. You do not have to wait for that notification; many people charge their Ring batteries on a schedule — say, once every two months — to avoid the device going offline unexpectedly.

Troubleshooting a Ring battery that will not charge

If your battery is not charging, first check the cable. The USB cable that comes with Ring devices can wear out or get damaged. Try a different USB cable — any standard USB-A to micro-USB cable will work. If a different cable charges the battery, the original cable is the problem.

Next, try a different charger. A weak or broken power adapter can fail to charge the battery even if the cable is fine. Plug the cable into a different USB charger — a phone charger, a computer, or a USB power bank — and wait 30 minutes to see if the battery percentage increases in the Ring app.

If the battery still will not charge, it may be defective. Lithium-ion batteries can fail, especially if they have been exposed to extreme heat or cold. Contact Ring support with your device serial number and purchase date; they can send you a replacement battery.

Frequently Asked Questions

Can I use any USB charger to charge my Ring battery?

Yes. Any standard USB charger will work, though faster chargers (2 amps or higher) will charge the battery more quickly. The cable that comes with your Ring is a standard USB-A to micro-USB cable, so you can replace it with any compatible cable if it gets damaged.

What happens if my Ring battery dies completely?

Your Ring doorbell will stop recording and go offline. You will not be able to see live video or get motion alerts. Once you charge the battery back to at least 5 percent, the device will reconnect to your WiFi and resume normal operation.

Is it bad to leave my Ring battery plugged in after it is fully charged?

No. Modern lithium-ion batteries and chargers are designed to stop charging once the battery reaches 100 percent, so leaving it plugged in overnight or longer will not damage it. However, unplugging it once it is fully charged is a good habit and saves a small amount of electricity.

Why does my Ring battery drain so fast in winter?

Cold temperatures reduce the capacity of lithium-ion batteries, so they drain faster and charge more slowly. If your Ring is mounted outside in freezing weather, this is normal. You may need to charge it more frequently during winter months.

Can I buy a second battery so I always have a charged one ready?

Yes. Ring sells replacement batteries separately, and you can keep a spare fully charged and swap it in when the one in your doorbell runs low. This is a practical solution if you want to avoid any downtime while charging.
