Ring doorbell batteries take two to four hours to charge fully, depending on which model you own and whether you use the official charger
The charging time for a Ring doorbell battery varies by model. The Ring Video Doorbell (2nd generation and newer) and Ring Video Doorbell Plus typically charge in two to four hours with the official USB charger. The Ring Video Doorbell Pro and Pro Max, which have larger batteries, may take closer to four hours. Older Ring models like the original Video Doorbell can take up to ten hours.
The charger you use matters. Ring's official USB charger delivers the correct power output and charges fastest. Using a different USB charger — even one rated for phones — can slow the process significantly or fail to charge the battery at all. The official charger comes with most Ring doorbells, but if you've lost it, you can buy a replacement from Ring's website or major retailers.
Temperature also affects charging speed. Cold batteries charge more slowly than warm ones. If your battery has been outside in winter, bring it indoors and let it warm to room temperature before charging. Charging a very cold battery can also damage it permanently, so patience here saves money later.
Key Takeaways
- Ring Video Doorbell models charge in two to four hours with the official USB charger, while older models may take up to ten hours.
- Using the official Ring USB charger is essential — third-party chargers often fail to charge the battery or charge it very slowly.
- Cold batteries charge more slowly and can be damaged by charging while frozen, so warm the battery to room temperature first.
- You can charge the battery while it remains in the doorbell, or remove it and charge it separately using the same USB charger.
Charging the battery in the doorbell versus removing it
You have two options: charge the battery while it sits in the mounted doorbell, or remove it and charge it at a desk or table. Both methods use the same official USB charger and take the same amount of time. Charging in place is convenient if you want to avoid removing the doorbell from your wall or door frame. Removing the battery is faster if you need your doorbell working immediately — you can swap in a second battery (if you own one) while the first charges.
To remove the battery, open the doorbell's faceplate by pressing the release button or tab on the side, depending on your model. The battery slides out easily. The USB charger has a small connector that plugs directly into the battery's charging port. You'll see a light indicator on the battery itself — usually red while charging and green when full. Leave the battery plugged in until the light turns green, even if it seems to stop changing after an hour or two.
Why your Ring battery might charge slowly
If your battery is taking longer than expected, the charger is usually the culprit. Check that you're using Ring's official USB charger, not a phone charger or generic USB cable. The connector should fit snugly into the battery's port with no wiggling. If the connection is loose, the battery may not charge at all, even though it appears to be plugged in.
A damaged charging port on the battery itself can also slow or prevent charging. If the port looks bent, corroded, or has debris inside, gently clean it with a dry cloth or a small brush. Do not use water or liquids. If the port is visibly bent, the battery may need to be replaced — Ring sells replacement batteries for most models at a reasonable cost.
Battery age matters too. Ring batteries degrade over time, especially if they've been exposed to extreme heat or cold for long periods. An older battery that once charged in two hours might take three or four hours after a year or two of use. This is normal wear and does not mean the battery is failing — it will still hold a charge and power your doorbell normally.
What to do while the battery charges
Your Ring doorbell will not record video or send notifications while the battery is removed and charging. If you need continuous monitoring, buy a second battery so you can swap them — one charges while the other powers the doorbell. Ring sells spare batteries individually, and they cost between thirty and fifty dollars depending on the model.
If you cannot wait and do not have a spare battery, you can temporarily power the doorbell with a USB cable connected to an outlet near your door. This is not a permanent solution, but it keeps the doorbell working during the charging period. Some Ring models support this, while others do not — check your doorbell's manual or Ring's support site to see if your model allows it.
How often you'll need to charge
Most Ring doorbells need charging every two to three months, depending on how much activity they see. A doorbell in a busy area with frequent motion detection and video recording will drain the battery faster than one in a quiet location. During winter, batteries drain faster because cold reduces their capacity. During summer, you might go three or four months between charges.
Ring's app will notify you when the battery is low, usually when it drops below twenty percent. You do not have to wait for this warning to charge — charging proactively every two months prevents the doorbell from going offline unexpectedly. If you travel frequently or want to avoid thinking about charging, consider a wired Ring doorbell instead, which draws power from your home's existing doorbell wiring and never needs charging.
Troubleshooting a battery that won't charge
If your battery will not charge after thirty minutes with the official charger, try these steps in order. First, unplug the charger and inspect the charging port on the battery for debris, corrosion, or bent pins. Use a dry cloth to clean the port gently. Plug the charger back in and wait another thirty minutes.
If the battery still does not charge, try a different USB power outlet — sometimes a wall outlet or USB hub is faulty. Plug the charger into a different outlet in your home and wait another thirty minutes. If the battery charges in the new outlet, the original outlet may be the problem.
If the battery does not charge in any outlet, it may be defective. Ring offers a one-year warranty on batteries from the date of purchase. Contact Ring's support team with your proof of purchase, and they can send you a replacement. If your battery is outside the warranty period, you can buy a new one from Ring or from retailers like Amazon or Best Buy.
Frequently Asked Questions
Can I use a phone charger to charge my Ring battery?
Phone chargers often have the wrong power output and may not charge the battery at all, or charge it very slowly. The official Ring USB charger is designed specifically for Ring batteries and charges them reliably in two to four hours. If you've lost your charger, buy a replacement from Ring's website rather than risk damaging the battery.
Is it bad to leave the battery charging overnight?
No, it is safe to leave the battery plugged in after it reaches full charge. The charger stops delivering power once the battery is full, so leaving it plugged in overnight will not damage the battery or the charger. The light indicator will show green, confirming the battery is fully charged.
Why does my battery drain so fast?
Frequent motion detection, video recording, and cold weather all drain the battery faster. If your doorbell is in a high-traffic area or near a street, it may record constantly and need charging every month instead of three months. Cold temperatures also reduce battery capacity — the same battery lasts longer in summer than in winter.
Can I charge the battery in freezing weather?
Avoid charging a battery that is below freezing. Bring the battery indoors and let it warm to room temperature before plugging in the charger. Charging a frozen battery can damage it permanently and reduce its lifespan. If your battery has been outside in winter, wait at least thirty minutes after bringing it inside before charging.
Do I need to fully drain the battery before charging it?
No, Ring batteries use lithium-ion technology and do not require a full drain before charging. You can charge the battery at any time, even if it still has fifty percent power remaining. Charging partially and frequently is actually better for long-term battery health than waiting until it is completely empty.
