Blink cameras use AA batteries, and most models take two of them
The standard Blink indoor and outdoor cameras run on two AA batteries. This is true for the Blink Mini (wired version), Blink Indoor, Blink Outdoor, and Blink Video Doorbell models. You do not need a special battery type — any standard AA alkaline battery from a grocery store or drugstore will work.
The Blink XT2 and original Blink Outdoor also use two AA batteries. If you own an older Blink model or a newer one, check the battery compartment on the back or bottom of the camera to confirm the slot size before you buy replacements.
Battery life varies by model and usage. Most Blink cameras last between one and two years on a single set of AA batteries, depending on how often motion detection triggers recording and how many live views you stream. Cold weather shortens battery life noticeably.
Key Takeaways
- Blink cameras use two AA alkaline batteries, which you can buy at any drugstore or supermarket.
- Battery life typically ranges from one to two years per set, though frequent motion alerts and live streaming drain them faster.
- The battery compartment is on the back or bottom of the camera and opens with a coin or screwdriver.
- Cold temperatures reduce battery life, so expect shorter performance in winter months.
How to locate and open the battery compartment
The battery compartment sits on the back of indoor Blink cameras and on the bottom of outdoor and doorbell models. Look for a small rectangular panel or door, usually marked with a battery symbol or the word "Battery."
To open it, use a coin (a dime or penny works) or a small flathead screwdriver and turn counterclockwise. Some models have a small tab you can pull instead. Once open, you will see two slots labeled with a plus and minus sign showing which direction the batteries go.
Insert the two AA batteries with the positive end (the flat side marked +) facing the direction indicated in the compartment. Close the door and turn clockwise until snug — do not force it.
When to replace your batteries
The Blink app will send you a notification when battery level drops to 20 percent. This gives you time to buy replacements before the camera stops working. You do not have to wait for the alert — you can check battery status anytime in the app under device settings.
Replace both batteries at the same time, even if only one is low. Mixing old and new batteries can cause one to drain faster and may damage the weaker one. After you insert new batteries, the app will update the battery percentage within a few minutes.
Alkaline versus rechargeable AA batteries
Standard alkaline AA batteries (like Duracell or Energizer) are the most common choice and work reliably in Blink cameras. They are cheap, widely available, and perform consistently in most conditions.
Rechargeable AA batteries (NiMH type, like Eneloop or Amazon Basics) also work in Blink cameras. They cost more upfront but save money over time if you replace batteries frequently. The trade-off is that rechargeable batteries have a lower voltage (1.2V instead of 1.5V) and may drain slightly faster in some models, though most users report acceptable performance.
Do not use carbon-zinc batteries (the cheapest type) — they drain too quickly in motion-detection devices. Stick with alkaline or rechargeable NiMH for best results.
Factors that drain batteries faster
Motion detection is the biggest battery drain. Every time the camera detects motion and records a clip, it uses power. If your camera is in a high-traffic area or pointed at a window where trees or cars move frequently, expect shorter battery life.
Live view streaming also drains the battery. Each time you open the app and watch the live feed, the camera is working harder. Frequent live views can cut battery life by several months.
Temperature matters. Batteries perform worse in cold weather — below 50 degrees Fahrenheit, you may see 20 to 30 percent shorter life. If your outdoor camera is in a cold climate, plan to replace batteries more often in winter.
WiFi signal strength affects battery drain too. A camera with a weak connection to your router works harder to stay connected and uses more power. Moving your router closer or adding a WiFi extender can help.
Blink battery models and their differences
| Camera Model | Battery Type | Quantity | Typical Life |
|---|---|---|---|
| Blink Indoor | AA alkaline | 2 | 1–2 years |
| Blink Outdoor | AA alkaline | 2 | 1–2 years |
| Blink XT2 | AA alkaline | 2 | 1–2 years |
| Blink Video Doorbell | AA alkaline | 2 | 1–2 years |
| Blink Mini (wired) | None — powered by USB | — | N/A |
The Blink Mini wired version is the only model that does not use batteries — it plugs into a USB power adapter. All other current Blink cameras use the same two-AA setup, so you can use the same batteries across multiple cameras if you own more than one.
Frequently Asked Questions
Can I use 9V batteries or other sizes in my Blink camera?
No. Blink cameras are designed for AA batteries only. The compartment will not fit other sizes, and using the wrong battery type can damage the camera. Stick with standard AA alkaline or rechargeable AA batteries.
Do I need to remove batteries before I reset my Blink camera?
No. Resetting the camera through the app does not require removing batteries. If you need to do a hard reset, the instructions will tell you to hold a button for a specific time — the batteries stay in place.
Why is my battery draining faster than the stated one to two years?
High motion activity, frequent live streaming, cold weather, and weak WiFi signal all shorten battery life. If your camera is in a busy area or outdoors in winter, expect to replace batteries every 6 to 12 months instead of 24 months.
Can I leave old batteries in the camera if I am not using it?
It is better to remove them. Old batteries can leak and damage the camera's battery contacts. If you plan to store a Blink camera for more than a month, take the batteries out and store them separately.
What should I do with old AA batteries after I remove them?
Take them to a battery recycling program. Most electronics stores (Best Buy, Staples) and some grocery stores have battery drop-off bins. Do not throw them in the trash — they contain materials that should be recycled.
