What Batteries do You Need for your Arlo Cameras

The Arlo Wire-Free Camera uses (4) CR123 lithium 3-volt photo batteries. Arlo wire-free cameras work best with non-rechargeable batteries that came with your Arlo Wire-Free Camera purchase, as well as non-rechargeable batteries from other high-quality, well-known, and established battery manufacturers.

Arlo prohibits the use of any rechargeable batteries with the Arlo Wire-Free Camera because they may damage your camera or pose a burn or fire hazard.

The Arlo Wire-Free Camera requires four batteries and it is not recommended to mix up batteries of different types and different brands as it could result in poor performance and less efficiency. So, all four batteries should be lithium batteries of the same brand.

Be careful not to confuse Lithium and Ion batteries. Lithium batteries are non-rechargeable. Never attempt to recharge these types of batteries because they may cause fires, etc.

What are CR123A Batteries?

CR123A batteries are categorized by their 34.5 x 17mm or 2/3A cell size, high 3-V, lithium (LiMnO2) chemistries. CR123A batteries are a great option for lithium camera batteries. They are non-rechargeable batteries.

Are there also Rechargeable CR123A Batteries?

Rechargeable CR123A batteries are referred to as RCR123A. They are shorter than the CR123As (16mm) and Lithium-Ion chemistries. They come with lower energy capacities and are usually 3.6 – m3.7 voltage. Not all cameras can use CR123A and RCR123A.

Why Use CR123A Batteries for Arlo Cameras

Arlo recommends the use of CR123A batteries for your Arlo security camera for numerous reasons.

Higher Voltage

CR123A batteries come with higher voltage as compared to other batteries so they can supply sufficient energy to your Alco Security Camera. CR123A batteries have a voltage of 3.0 volts (nominal).  The most common voltage of a CRA123A battery is 3.7 volts.

No Voltage Drops

A Lithium CR123A battery has a steady voltage curve allowing high power for the battery. Voltage drops can cause unpredictable performance which could compromise a security system especially those connected to wireless networks.

Lighter Weight

The CR123A has a lighter weight than most batteries. Most CR123A batteries are lighter than AA batteries.

Longer Battery Life

The CRA123A, on average, has a battery life of 3 – 5 years that is why it is known as a camera battery. These batteries are durable and last longer compared to other types of batteries.

Rechargeable vs. Non-Rechargeable Batteries

Arlo says their Wire-Free Cameras are for use with non-rechargeable batteries, non-rechargeable Lithium batteries for that matter. Lithium batteries work best with Arlo cameras because they are long-drain devices that run 24/7 but only work at a fraction of that time (when they detect motion).

Non-rechargeable lithium batteries can withstand extreme temperatures making them ideal for outdoor Arlo cameras and other outdoor fixtures.

Non-rechargeable Lithium batteries also last longer than rechargeable batteries. Rechargeable batteries last longer because you can recharge them.

When comparing rechargeable and non-rechargeable Lithium batteries, you need to take in consideration their applications.

Rechargeable batteries work best in high-drain electronic devices that need a lot of energy. Non-rechargeable Lithium batteries work best in long-draining devices that need a constant stream of low power such as Arlo security cameras.

How to Replace Batteries of Arco Cameras

Non-rechargeable CR123A batteries meet all power and reliability requirements of Alco security cameras. They work well in keeping your securing cameras up and running while not being too hard on your budget.

They are a few steps you need to do when replacing the batteries of your Alco cameras.

  1. Remove the old batteries.
  2. Shut off your router.
  3. Turn on the power of your router.
  4. Insert the new batteries into your cameras.
  5. Re-sync your cameras.

How long does a CR123A Battery Last?

How long a battery lasts depends on the battery consumption of your device, how intense it is used, the ambient temperature, and a lot of other factors. It also depends on the frequency of its use, except for security cameras wherein batteries are constantly in use.

If you use CR123A batteries in your Arlo alarm sensor, they may last for about 3 to 5 years. As a general rule, though, the lifespan of  CR123A batteries depends upon the device you use it with and how you use the batteries.

Are CR123A and CR123 Batteries the Same?

Yes. CR123A and CR123 batteries are the same. These batteries are also often referred to as 123, 123A. DL123, DL123A, and SF123.

The letter C in CR123A and CR123 signifies that it is a lithium battery. The letter R stands for round and 123 means one-third. So, it means, 123 batteries are one-third the size of cell batteries. Some manufacturers add the letter A to show that it is an A cell.

CR123A Batteries for Arlo Cameras

Read on to learn more about the CR123A before you decide to insert them in your Argo cameras.

All CR123A batteries are lithium batteries. They are not hazardous to the environment but need to be disposed of properly. Since these batteries mostly come in bulk packs, they can be safely stored in a cool, dry place under normal temperature.

This is one of the most important things that you should remember about the batteries you insert in your Arlo cameras. Never insert two batteries will different types or even brands. If you do, you run the risk of these batteries leaking and, thus, affecting the performance of your Arlo camera.
