The battery in your Ring doorbell lasts about six to twelve months depending on how many people press it and how cold it gets, then you remove it, charge it separately, and put it back in

Ring doorbells use a rechargeable lithium battery that sits inside the device. When the battery runs low, the Ring app sends you a notification. You do not need tools, a technician, or a replacement part — you take out the existing battery, charge it with a USB cable, and reinstall it. The whole process takes about five minutes, plus however long you leave the battery charging (usually two to three hours for a full charge from empty).

The battery does not wear out in the way a traditional alkaline battery does. Instead, it holds less charge over time, the same way a phone battery does after a few years. Most people replace the battery once a year or once every eighteen months. You can buy a replacement battery from Ring's website or from retailers like Amazon for around thirty to fifty dollars, but recharging the original battery works just as well and costs nothing.

Key Takeaways

  • Ring doorbell batteries last six to twelve months before needing a charge, and the app notifies you when the battery is low.
  • You remove the battery by loosening a single screw on the bottom of the device — no special tools required.
  • Charge the battery with any standard USB-to-micro-USB cable, which takes two to three hours from empty to full.
  • The battery is the same whether you own a Ring Video Doorbell 3, 4, or Pro model, though the screw location varies slightly.
  • If your battery drains faster than expected, check whether your Wi-Fi signal is weak or whether the device is in direct sunlight.

How to remove the battery from your Ring doorbell

Start by looking at the bottom of your Ring doorbell. You will see a single Phillips-head screw holding a small metal plate in place. Use a Phillips-head screwdriver to loosen this screw — you do not need to remove it completely, just loosen it enough that the plate slides out. On some Ring models, the screw is on the side rather than the bottom, so check your specific device if the bottom is blank.

Once the plate is loose, gently slide it downward or to the side (depending on your model) to expose the battery. The battery is a rectangular black or silver block about the size of a deck of cards. Grip it firmly and pull it straight out toward you. Do not force it — if it does not slide out easily, make sure the metal plate is fully loose.

Set the battery aside on a clean, dry surface. You now have access to the charging port on the back of the battery, which is a small micro-USB socket. This is where you will plug in your charging cable.

Charging the battery and reinstalling it

Use any standard USB-to-micro-USB cable — the same type that charges older Android phones or many portable speakers. Plug the micro-USB end into the battery and the USB end into a wall adapter or computer. A wall adapter rated for at least 1 amp (1000 mA) charges the battery fastest, though any USB power source works.

The battery has a small LED light on the front. When you first plug it in, the light will be red. As the battery charges, the light will turn orange, then green when fully charged. This usually takes two to three hours from a completely empty battery. You can leave it charging longer without damage — the battery will not overcharge.

While the battery charges, your Ring doorbell will not function. If you need the doorbell to work during this time, Ring sells a separate backup battery that you can swap in, but most people straightforward charge during a time when they do not expect visitors. Once the light turns green, unplug the cable and slide the battery back into the device, pushing it in until it clicks. Tighten the metal plate screw, and your doorbell is ready to use again.

Why your Ring battery drains faster than expected

If your battery is running out every two or three months instead of six to twelve, something is causing the device to work harder than normal. The most common cause is a weak Wi-Fi signal. Ring doorbells use Wi-Fi to send video and notifications, and a weak signal forces the device to transmit more often and use more power. Check your Wi-Fi signal strength in the Ring app — if it shows two bars or fewer, move your router closer or add a Wi-Fi extender near the doorbell.

Direct sunlight and extreme heat also drain the battery faster. If your doorbell faces west and gets afternoon sun, or if you live in a hot climate, the battery will naturally discharge more quickly. This is not a malfunction — it is how lithium batteries behave in heat. There is no way to prevent this, but it is not a sign that your device is broken.

A third cause is frequent motion detection or button presses. If your doorbell is near a busy street, a tree with moving branches, or a high-traffic entryway, the camera is recording and transmitting video constantly. Each recording uses battery power. If this is your situation, you can reduce motion sensitivity in the Ring app settings, though this means you might miss some events.

When to replace the battery instead of recharging it

After two or three years of regular charging, the battery will hold less and less charge each time. You might notice that it now only lasts three months instead of six, even though you charge it fully. At this point, the battery has reached the end of its useful life and should be replaced with a new one.

Ring sells replacement batteries on its website and through Amazon. The battery costs between thirty and fifty dollars depending on your region and current sales. Installation is identical to the process above — remove the old battery, insert the new one, and tighten the screw. The new battery will come partially charged, so your doorbell will work when ready, though you may want to charge it fully before relying on it for a full six months of use.

If your battery is only a few months old and already draining quickly, contact Ring's support team before buying a replacement. A defective battery is rare but possible, and Ring will often replace it at no cost if it is still under warranty.

Hardwired Ring doorbells and battery backup

Some Ring models, particularly the Ring Video Doorbell Pro and Pro 2, can be hardwired directly to your home's existing doorbell wiring. If your doorbell is hardwired, it draws power from your home's electrical system and does not rely on the battery for normal operation. The battery in a hardwired model serves as a backup in case the power goes out.

Hardwired batteries drain much more slowly because they are only used during power outages. You may only need to charge them once every two or three years. The removal and charging process is identical — loosen the screw, pull out the battery, charge it with a USB cable, and reinstall it. If you are not sure whether your doorbell is hardwired, check the Ring app settings or look behind the device for wires connected to your home's electrical system.

Frequently Asked Questions

Can I use my Ring doorbell while the battery is charging?

No. The battery must be removed from the device to charge it, so the doorbell will not function during charging. Charging usually takes two to three hours. If you need the doorbell to work during this time, you can purchase a second battery from Ring and swap them, or wait to charge during a time when you do not expect visitors.

What type of USB cable do I need to charge the battery?

Any standard USB-to-micro-USB cable works. These are the same cables used for older Android phones, Bluetooth speakers, and many other devices. If you do not have one, they cost a few dollars at any electronics store. The wall adapter should provide at least 1 amp of power, though any USB power source will eventually charge the battery.

Is it normal for the battery to get warm while charging?

Slight warmth is normal, especially if you are charging from completely empty. If the battery becomes hot to the touch or smells unusual, unplug it when ready and contact Ring support. This is rare, but it can indicate a defective battery that should be replaced.

Do I need to fully drain the battery before charging it?

No. Lithium batteries like the one in your Ring doorbell do not have a "memory" and do not need to be fully drained before recharging. You can charge it whenever it is convenient, even if it still has some charge left. Charging from empty takes longer, but charging from half-full works just as well.

What should I do with an old Ring battery?

Lithium batteries should not be thrown in the trash. Take it to an electronics recycling center, a Best Buy store (which accepts batteries for recycling), or check your city's hazardous waste disposal schedule. Some retailers that sell Ring batteries also accept old batteries for recycling.
