Ring Doorbell Batteries Charge in 5 to 10 Hours With a Standard USB Cable
A fully drained Ring doorbell battery takes between 5 and 10 hours to reach full charge when you use the USB charging cable that comes in the box. The exact time depends on which Ring model you own and the power output of the USB adapter you plug it into. A standard 1-amp adapter will charge more slowly than a 2-amp adapter.
You do not need to remove the battery from the doorbell to charge it. Ring batteries are removable, and you charge them by connecting the USB cable directly to the battery itself — not to the doorbell. This means you can charge one battery while another is installed in your doorbell, which is useful if you want continuous operation.
The battery does not need to be completely empty before you charge it. You can top it up at any point, and partial charges take proportionally less time. A battery at 50 percent will reach full charge in roughly 2.5 to 5 hours.
Key Takeaways
- Ring doorbell batteries charge in 5 to 10 hours with the included USB cable, depending on your adapter's power output and the battery model.
- You remove the battery from the doorbell and plug the USB cable directly into the battery to charge it, not into the doorbell itself.
- A 2-amp USB adapter charges faster than a 1-amp adapter, so using a higher-output charger can reduce charging time by 1 to 2 hours.
- Partial charges take less time — a battery at 50 percent charge will reach full in roughly half the time of a complete charge from empty.
- You can install a second battery in the doorbell while the first one charges, so you do not lose video recording during the charging period.
Which Ring Models and Battery Types Determine Charging Speed
Ring makes several doorbell models, and not all use the same battery. The Ring Video Doorbell (2nd Gen), Ring Video Doorbell (3rd Gen), and Ring Video Doorbell 4 all use the same rechargeable lithium-ion battery, which charges in 5 to 10 hours. The Ring Video Doorbell Pro uses a wired power connection and does not have a removable battery, so charging time does not explore to that model.
The Ring Video Doorbell Wired (released in 2023) also runs on wired power and has no battery to charge. If you own a Ring Video Doorbell Elite or the original Ring Video Doorbell, those models use the same battery type and charging time as the 2nd and 3rd generation models.
The battery capacity is the same across these models — 4,000 mAh — so the charging time does not vary between them. What changes the speed is the USB adapter you use and how much charge is already in the battery.
USB Adapter Power Output Makes a Real Difference
The USB cable that comes with your Ring doorbell is the same for all models, but the adapter you plug it into matters. Ring includes a 1-amp adapter in the box. If you use that adapter, expect the full 5 to 10 hours for a complete charge.
If you use a 2-amp adapter instead — common on phone chargers and tablet chargers — you can reduce charging time to roughly 4 to 6 hours. A 2.4-amp adapter will charge even faster. The higher the amp rating on your adapter, the quicker the charge, but Ring does not recommend using adapters above 2.4 amps, as they can damage the battery.
Check the label on any USB adapter you already own. Most modern phone chargers are 2 amps or higher. If you want to speed up charging and do not have a higher-output adapter, buying a 2-amp USB power adapter costs between $10 and $20.
How to Charge Your Ring Doorbell Battery Correctly
Remove the battery from the doorbell by pressing the release button on the back of the battery and sliding it out. The battery is a rectangular block about the size of a deck of cards. Do not try to charge the battery while it is still installed in the doorbell — the USB port is on the battery itself, not on the doorbell housing.
Plug the USB cable into the port on the battery. The cable has a micro-USB connector on one end. Plug the other end into your USB adapter, then plug the adapter into a wall outlet. A light on the battery will indicate charging status — usually a red light means charging, and a green light means fully charged.
Leave the battery plugged in until the light turns green. Do not unplug it early, as the battery may not hold a full charge. Once it is fully charged, unplug the cable and reinstall the battery in the doorbell by sliding it back in until you hear a click.
Charging Time During Different Seasons and Weather
Ring doorbell batteries drain faster in cold weather because lithium-ion batteries lose efficiency in low temperatures. If you live somewhere with winters below 40 degrees Fahrenheit, you may need to charge your battery more often — potentially every 2 to 4 weeks instead of every 3 to 6 months. This does not change how long charging takes, but it means you will be charging more frequently.
Hot weather does not significantly affect charging time, but it can reduce the overall lifespan of the battery over years of use. Storing a fully charged battery in a cool, dry place when you are not using it helps preserve its capacity.
If your battery will not hold a charge or charges much more slowly than 5 to 10 hours, the battery may be failing. Ring batteries typically last 2 to 3 years before they need replacement. A replacement battery costs between $30 and $50 depending on the model.
What to Do If Your Battery Is Charging Slowly
If your battery is taking longer than 10 hours to charge, check the USB adapter first. Plug the adapter into a different outlet to rule out a faulty wall socket. If it still charges slowly, try a different USB adapter with a higher amp rating — a 2-amp adapter instead of the 1-amp one that came in the box.
Inspect the USB cable for damage. If the cable is bent, cracked, or the connector is loose, it may not deliver power efficiently. A damaged cable should be replaced; Ring sells replacement cables for around $15.
If you have tried a different outlet, a different adapter, and a different cable and the battery still takes more than 10 hours to charge, the battery itself may be degraded. This is normal after 2 to 3 years of regular use. Order a replacement battery from Ring or an authorized retailer.
Having a Second Battery Means No Downtime
Ring sells a spare battery for most of its battery-powered models. The spare battery costs between $30 and $50. If you buy a second battery, you can charge one while the other is installed in your doorbell, so your video recording never stops.
This is especially useful if you live in a cold climate where batteries drain quickly, or if you want to avoid the 5 to 10 hour wait when your battery runs low. straightforward swap the batteries — remove the drained one, install the charged one, and plug the drained battery in to charge while you continue recording.
If you have two batteries, you can stagger charging so that one is always ready. Charge one battery while the other is in use, then swap them when the installed battery reaches 20 to 30 percent charge. This approach keeps your doorbell running continuously without gaps in video coverage.
Frequently Asked Questions
Can I charge my Ring doorbell battery while it is still installed in the doorbell?
No. The USB charging port is on the battery itself, not on the doorbell. You must remove the battery by pressing the release button on the back and sliding it out, then plug the USB cable directly into the battery. The doorbell does not charge the battery — only the USB cable does.
What happens if I use a USB adapter with more than 2.4 amps?
Ring does not recommend using adapters above 2.4 amps because they can overheat and damage the battery. Stick to adapters rated between 1 and 2.4 amps. A 2-amp adapter is the fastest safe option and will charge your battery in 4 to 6 hours instead of 5 to 10.
How often do I need to charge my Ring doorbell battery?
Charging frequency depends on how much motion your doorbell detects and your climate. In mild weather with moderate activity, most users charge every 3 to 6 months. In cold weather or high-activity areas, you may charge every 2 to 4 weeks. The Ring app shows your battery percentage, so you can charge whenever it drops below 20 percent.
Is it bad to leave my battery plugged in after it reaches full charge?
No. Modern lithium-ion batteries like the one in your Ring doorbell have built-in protection that stops charging once the battery is full. Leaving it plugged in overnight will not damage it. However, unplugging it once it reaches full charge is a good habit and saves a small amount of electricity.
Can I use any micro-USB cable to charge my Ring doorbell battery?
Yes, any standard micro-USB cable will work. You do not need to buy a Ring-branded cable. However, make sure the cable is in good condition — a damaged or loose connector will charge slowly or not at all. If you are having charging problems, try a different cable before assuming the battery is faulty.
