Ring doorbells primarily use two AA lithium batteries for power. These batteries provide consistent energy in extreme temperatures and last longer than alkaline cells. Most Ring models, including the Ring Video Doorbell 2, Ring Video Doorbell Pro, and Ring Video Doorbell Elite, rely on this configuration.
Lithium AA batteries offer higher voltage (1.5V nominal) and better performance in cold climates compared to standard alkaline batteries. They maintain capacity over time, making them ideal for outdoor devices exposed to weather fluctuations. The battery compartment is accessible via a small screwdriver or the included tool, located near the base of the device.
For users who prefer not to replace batteries regularly, Ring offers solar-powered options. The Ring Solar Panel for Video Doorbell attaches to the back of select models, reducing reliance on disposable batteries. However, even solar-equipped units include AA batteries as backup during low-light conditions.
Ring doorbells draw power from AA lithium batteries to operate motion detection, video recording, and two-way audio. The device activates when motion is detected or the doorbell button is pressed. Power consumption spikes during video events, especially when recording in high resolution or using night vision.
Battery life varies based on usage frequency. A typical Ring Video Doorbell 2 lasts between 6 and 12 months on a single set of AA lithium batteries under average use. Heavy usage-such as frequent motion triggers or continuous live view sessions-can reduce lifespan to as little as four months.
The doorbell includes a battery indicator in the Ring app. When the charge drops below 20%, the app sends a notification. This feature prevents sudden shutdowns during critical moments, such as when a visitor arrives or suspicious activity occurs.
Not all batteries are equal. Ring recommends using only high-quality AA lithium batteries. Alkaline batteries may work initially but degrade quickly in cold weather and fail prematurely. Rechargeable NiMH batteries are not recommended due to lower voltage and inconsistent performance.
| Battery Type | Voltage | Expected Life | Best For |
|---|---|---|---|
| Alkaline (AA) | 1.5V | 3-6 months | Occasional use in mild climates |
| Lithium (AA) | 1.5V | 6-12 months | Standard use, cold climates |
| Rechargeable NiMH (AA) | 1.2V | 2-4 months | Not recommended by Ring |
Some users report that certain brands of lithium batteries-like Energizer Ultimate Lithium-last longer than others. Independent testing by Consumer Reports confirmed that these batteries retain 90% of their capacity after 10 years of storage, outperforming alkaline cells by over 50% in low-temperature environments.
Using counterfeit or generic batteries risks damage to the doorbell's internal circuitry. Ring's official support documentation warns against third-party batteries that do not meet IEC standards for size, voltage, and safety certification.
AA lithium batteries are used because they deliver stable voltage under stress and temperature extremes. Outdoor doorbells face freezing winters and scorching summers. Standard batteries lose efficiency above 60°C or below -20°C. Lithium chemistry maintains performance across a wider range-typically -40°C to 70°C.
These batteries are also lightweight and compact, fitting precisely into the doorbell's sealed housing. Their design prevents leakage, a common issue with alkaline batteries left in devices for extended periods. Leaked electrolyte can corrode contacts and permanently disable the unit.
For example, a homeowner in Anchorage, Alaska, reported that their Ring Video Doorbell 2 continued functioning through a winter with temperatures dropping to -30°C. The original lithium batteries remained effective, while a neighbor's device using alkaline cells failed after two weeks.
Many assume Ring doorbells run solely on AC power. While hardwired models exist, most Ring devices are battery-operated. Even wired versions include batteries as backup during power outages. The Ring Video Doorbell Pro, for instance, supports both hardwired and battery-only modes.
Another misconception is that all Ring doorbells use the same battery model. The Ring Video Doorbell 3 uses a different internal connector than earlier models. Attempting to swap batteries between generations can damage the contact points or prevent proper seating.
A lesser-known fact: Ring doorbells do not use coin-cell batteries like those in watches or remote controls. The AA format was chosen for ease of replacement and availability. You can buy AA lithium batteries at grocery stores, hardware outlets, or online retailers-no special tools required.
I once replaced the batteries in my Ring Video Doorbell Pro during a storm. The device had stopped sending alerts. After installing fresh AA lithium cells, it resumed normal function within 30 seconds. The process took less than five minutes, and the battery indicator in the app updated immediately.
To replace batteries, remove the front panel using the included screwdriver. Lift the cover to access the battery tray. Slide out the old cells and insert two new AA lithium batteries with correct polarity. Reattach the cover and press the reset button if prompted.
For optimal longevity, avoid leaving the doorbell in direct sunlight or near heat sources. High ambient temperatures accelerate battery degradation. Store spare batteries in a cool, dry place-ideally between 10°C and 25°C.
If your Ring doorbell shows "Low Battery" frequently despite fresh batteries, check for firmware updates. Outdated software can misreport battery levels. Update via the Ring app under Device Settings > Firmware Update.
Always dispose of used batteries properly. Lithium batteries should not be thrown in regular trash. Many retailers, including Home Depot and Best Buy, offer free battery recycling bins. Local hazardous waste facilities accept them too.
Understanding what batteries do Ring doorbell use ensures uninterrupted security monitoring. Using the correct AA lithium cells improves reliability, extends device life, and avoids unexpected failures during peak usage times.
