Ring battery devices charge in two to four hours on average

Most Ring doorbells and cameras with removable batteries take between two and four hours to reach a full charge when plugged into a standard USB power adapter. The exact time depends on which Ring model you own, the power output of your adapter, and whether the device is in use while charging. A Ring Video Doorbell (2nd Generation) typically needs about three hours, while smaller cameras like the Ring Stick Up Cam may charge faster at closer to two hours.

The battery itself is a rechargeable lithium-ion pack that comes out of the device. You remove it, plug the included charging cable into the battery (not the camera), and connect that cable to any USB power source — a wall adapter, computer, or power bank all work. Ring does not recommend charging the battery while it remains installed in the device, though some newer models support in-device charging through a wired connection.

Key Takeaways

  • Ring battery devices charge in two to four hours using a standard USB adapter and the cable that comes in the box.
  • Charging time varies by model: smaller cameras charge faster than full-size doorbells, and older models may take longer than newer ones.
  • A higher-output USB adapter (2 amps or more) will charge the battery faster than a low-power phone charger.
  • You should remove the battery from the device before charging it, unless your specific Ring model supports in-device charging.
  • Most Ring batteries hold a charge for several months in normal use, so you may only need to charge every few months rather than weekly.

Charging time by Ring model

Ring makes several battery-powered models, and they do not all charge at the same speed. The Ring Video Doorbell (2nd Generation) and Ring Video Doorbell (3rd Generation) both take roughly three hours. The Ring Stick Up Cam and Ring Stick Up Cam Elite charge in about two hours because they have smaller batteries. The Ring Spotlight Cam and Ring Floodlight Cam, which are larger, may take up to four hours.

If you own an older Ring model from before 2020, check the manual that came with it or the product page on Ring's website — charging times for discontinued models are not always listed in current support documents. Ring has also released newer versions of most cameras, and the newer versions sometimes charge faster due to improved battery chemistry or charging circuits.

How the power adapter affects charging speed

The charging cable that comes with your Ring device is the same for all models, but the USB power adapter you plug it into makes a real difference. A standard phone charger outputs 1 amp. Ring batteries charge noticeably faster with a 2-amp or higher adapter — you may cut 30 to 45 minutes off the total time. Many modern wall adapters for tablets or laptops output 2 amps or more and will speed up charging.

Plugging the battery into a computer's USB port will charge it, but much more slowly — computer USB ports typically output only 0.5 amps. A power bank works fine as long as it has enough charge left to complete the job. Ring does not publish a specific amp requirement, but 2 amps is a safe standard that will not damage the battery and will charge it at a reasonable pace.

What to do while the battery charges

You cannot use your Ring device while the battery is out being charged. If you need continuous video coverage, you have two options: buy a second battery and swap them, or choose a wired Ring model instead. Many people who own battery Ring devices keep a spare battery on hand so one is always charging while the other is in use.

A spare battery costs between $30 and $50 depending on the model. If you charge one battery while using the other, you will never have a gap in coverage. This is especially useful if your Ring device is your primary security camera or if you live somewhere with frequent motion alerts.

How often you actually need to charge

Ring batteries do not need charging every week or even every month for most users. A fully charged battery lasts anywhere from two to six months depending on how many times the camera records video, how many motion alerts it sends, and the weather. Cold temperatures drain batteries faster, so winter may require more frequent charging than summer.

If your Ring device records video constantly or you have motion detection set to very high sensitivity, the battery will drain faster and you may need to charge every six to eight weeks. If the camera sits in a quiet area with few motion events, you might go three to four months between charges. Ring's app shows your battery level, so you can check it whenever you want and charge before it runs completely dead.

Troubleshooting slow or failed charging

If your battery is taking much longer than the expected time to charge, first check that the charging cable is fully inserted into both the battery and the power adapter. A loose connection will charge very slowly or not at all. Try a different USB power adapter if you have one available — a faulty adapter is a common cause of slow charging.

If the battery still will not charge after trying a different adapter and cable, the battery itself may be defective. Ring batteries are covered by a one-year warranty from the date of purchase. Contact Ring support with your proof of purchase and they can send you a replacement. Do not attempt to open or repair the battery yourself — lithium-ion batteries can be dangerous if damaged.

Frequently Asked Questions

Can I charge the battery while it is still in the Ring device?

Most Ring models require you to remove the battery before charging. However, some newer Ring doorbells support in-device charging through a USB-C or micro-USB port on the back of the device. Check your product manual or Ring's website for your specific model — if it supports in-device charging, it will be clearly stated in the specifications.

What happens if I leave the battery plugged in after it is fully charged?

Ring batteries have built-in protection that stops charging once they reach 100 percent, so leaving the battery plugged in overnight will not damage it. However, it is not necessary — you can unplug it as soon as the indicator light shows it is full. Unplugging it will not harm the battery either way.

Why is my Ring battery draining so fast?

Fast battery drain is usually caused by high motion detection sensitivity, frequent video recording, or cold weather. Check your Ring app settings and lower motion sensitivity if you do not need alerts for every small movement. Cold temperatures can cut battery life in half, so if you live somewhere with harsh winters, plan to charge more often during those months.

Is it safe to use a fast charger or high-amp adapter?

Ring batteries are safe with adapters up to 2 amps. Higher-amp adapters designed for tablets or laptops will not damage the battery because the charging circuit inside the battery regulates how much power it accepts. Using a 2-amp or higher adapter is actually the best way to charge quickly without any risk.

Can I charge my Ring battery with a wireless charger?

No. Ring batteries only charge through the wired USB cable that comes with them. Wireless charging is not supported on any Ring battery model. You must use the included cable and a USB power source.
