Ring doorbell batteries charge in 5 to 10 hours on a standard USB power adapter
The time depends on which Ring model you own and the power output of your charger. Ring's standard USB charger delivers 1 amp, and most doorbell batteries reach full charge in that window. If you use a higher-amperage charger — say 2 amps or more — the battery may charge faster, though Ring does not officially recommend exceeding 1 amp. A completely dead battery takes longer than one that is partially depleted.
The battery itself is removable on most Ring models. You take it out, plug the USB cable into the battery's charging port, and connect the other end to a wall outlet or computer USB port. The battery has a small LED light that turns red while charging and green when full. Some users report the light stays red for hours, then switches to green suddenly near the end — this is normal behavior.
Key Takeaways
- A Ring doorbell battery charges fully in 5 to 10 hours using the standard 1-amp USB charger that comes in the box.
- The removable battery has a red LED while charging and a green LED when fully charged, so you can see the status without unplugging it.
- Using a charger with higher amperage than 1 amp may speed charging but is not officially supported by Ring.
- A battery that is completely dead takes longer to charge than one that still holds partial charge.
- You can charge the battery outside the doorbell, so you do not have to leave your doorbell unplugged while waiting.
Charging times for different Ring doorbell models
Ring makes several doorbell models, and battery capacity varies. The Ring Video Doorbell (2nd generation) and Ring Video Doorbell (3rd generation) both use the same battery and charge in roughly 5 to 10 hours. The Ring Video Doorbell Pro uses a wired power supply and does not have a removable battery, so this charging time does not explore to it.
The Ring Video Doorbell Plus and Ring Video Doorbell Pro 2 also use wired power and do not charge via USB. If you own one of these models, you will not be removing a battery to charge it. Check your doorbell's model number on the back of the device or in the Ring app under device settings if you are unsure which version you have.
What to do while the battery charges
Because the battery is removable, you can charge it indoors while your doorbell stays mounted at your door. This means you do not lose video coverage while charging. Unscrew the battery from the back of the doorbell, bring it inside, and plug it in. The doorbell will not record video while the battery is out, but it will not be damaged by the removal.
If your doorbell is hardwired to a power source in addition to having a battery, it may continue to operate on the wired connection even while the battery is charging elsewhere. Check your installation to see if your doorbell has both a battery and wired power. If it runs on battery only, you will have no video recording until you reinstall the charged battery.
Signs your battery is fully charged
The green LED on the battery itself is the clearest indicator. When the light turns solid green, the battery is ready to use. Some chargers also have their own LED — usually a green light on the USB adapter — but the battery's light is what matters. Do not rely on the charger's light alone, because it may indicate that power is flowing, not that the battery is full.
Once the battery shows green, unplug it from the charger and screw it back into your doorbell. The doorbell will power on and resume recording within a few seconds. If you leave the battery plugged in after it reaches full charge, it will not overcharge or damage the battery — modern chargers stop delivering current once the battery is full — but there is no benefit to leaving it connected.
Troubleshooting slow or stalled charging
If your battery is taking much longer than 10 hours or the LED never turns green, check that the USB cable is fully inserted into both the battery port and the wall outlet. A loose connection will interrupt charging. Try a different USB cable if you have one, because the original cable may be damaged.
If the battery still will not charge, the battery itself may be defective. Ring batteries typically last 1 to 2 years depending on how often your doorbell records. If your battery is older than that and has been charged hundreds of times, it may no longer hold a charge. Contact Ring support with your device's serial number and purchase date — they can send a replacement battery under warranty if it is still covered.
Extremely cold temperatures can also slow charging. If you are charging the battery in a very cold room or garage, move it to room temperature and try again. Lithium batteries charge more slowly in cold conditions and may not charge at all below freezing.
How often you need to charge the battery
Charging frequency depends on how much video your doorbell records. A doorbell in a quiet area with few visitors and no motion detection enabled may go 2 to 3 months between charges. A doorbell in a busy location with motion detection on and frequent video recording may need charging every 2 to 4 weeks.
The Ring app shows your battery percentage in the device settings. Check it once a month to see how quickly it drains in your situation. If it drops below 20 percent, charge it soon — do not wait until it is completely dead, because a fully depleted battery can take longer to revive. Some users charge their batteries on a regular schedule, like once a month, rather than waiting for the battery to run low.
Frequently Asked Questions
Can I use a fast charger with my Ring doorbell battery?
Ring specifies a 1-amp charger, and using a charger with significantly higher amperage is not officially supported. A 2-amp charger may work without damage, but Ring does not test or recommend it. Stick with the charger that came in the box or a replacement rated for 1 amp to avoid any risk.
What if I lose the USB charging cable?
Ring sells replacement charging cables on its website and through Amazon. You can also use any standard micro-USB cable rated for at least 1 amp, though Ring's cable is designed specifically for the battery connector. A generic micro-USB cable from another device may fit loosely and cause charging to fail, so a Ring cable is the safer choice.
Can I charge the battery while it is still in the doorbell?
No. The battery is designed to be removed before charging. Attempting to charge it while mounted in the doorbell will not work because the charging port is not accessible. You must unscrew the battery from the back of the doorbell first.
Does the doorbell record while the battery is charging?
Not if the battery is the only power source. Once you remove the battery, the doorbell has no power and cannot record. If your doorbell is also hardwired to a power supply, it will continue recording on wired power while the battery charges separately.
How do I know if my battery is dead and needs replacement?
If the battery will not hold a charge for more than a few days even after a full charge cycle, or if it will not charge at all after 12 hours, the battery is likely worn out. Ring batteries typically last 1 to 2 years. Contact Ring support with your device serial number to order a replacement.
