How Long Do Wireless Security Camera Batteries Last (Guide)

Typically, wireless security cameras last 3 to 6 months. But you can increase life by using disabling night vision, betting on a better internet connection, and allowing the battery to completely drain before you recharge it. 

Wireless security cameras work with batteries and typically last 3-6 months. Learn how to maximize battery life and how to replace them with us below. 

Wireless security cameras have their own place in the security camera market. These cameras run on onboard batteries and transmit data wirelessly through WiFi. This gives these cameras some exclusive advantages over traditional wired security cameras.  

Battery Life of the Most Popular Wireless Security Cameras

Since these cameras do not require any intrusive changes to be made, they are really easy to mount and set up. These cameras can also be mounted almost anywhere, allowing you to surveil from almost any location without worrying about how the wires will get there. But batteries have a limited life. The following chart shows the battery life of some of the most popular wireless security cameras in the market.

What Types of Security Camera Batteries Last Longest?

There are three main types of batteries used in security cameras today. Li-Ion batteries, Ni-Cd batteries, and Ni-MH batteries. Each of these types has its pros and cons. We are going to discuss these separately.

Using Alkaline or Rechargeable Li-Ion, Ni-Cd, or Ni-MH Batteries

NiCd (Nickle Cadmium) Batteries 

Nickel Cadmium batteries are the cheapest of the batteries. The batteries are now an older technology, and they suffer from what’s called the lazy battery effect. If you charge these batteries before they are fully discharged, they “memorize” the new charging cycle and decrease their battery life. The way to avoid this problem is to let the battery discharge completely before you change it. (1)

If the lazy battery effect is properly dealt with, these batteries have impressive longevity. They can be charged and discharged 1000 times. This amounts to charging the battery once a day for three years. Wireless security cameras need to be charged every six months or more, so you will not be using the 1000 charges. 

Ni-MH (Nickle-Metal Hydride) Batteries

These batteries cost more than NiCd batteries, but they don’t have the lazy battery effect problem. These batteries can be charged and partially discharged as many times as you like. They will not drop in their capacity due to the lazy battery effect. 

Nickle-metal hydride batteries have a significantly larger capacity than NiCd batteries. These batteries are also fairly common, and their chargers are quite easy to find. (2)

These batteries have a higher energy density and provide more power. This means these batteries occupy less space in the camera. 

However, these batteries take longer to charge, and they are sensitive to extreme changes in temperature. 

Lithium-ion Batteries

Li-ion batteries are more compact and lighter in weight than other batteries. These batteries are also able to provide a higher voltage. These batteries also have a low self-discharge rate compared to other batteries. This means that the capacity of a Li-ion battery will stay the same for a long time. 

These batteries can be charged much faster and not more tolerant to changes in temperature. They also have a high energy density. 

One downside of these batteries is that they are not compatible with other chargers and require a special charger. But if you buy a wireless camera, the charger will be included. 

Does Battery Size Matter?

Size is definitely one of the factors that determine how long a battery lasts, but it’s certainly not the only factor. The type of battery and the chemistry of the battery plays a much larger role in determining everything from battery life, battery capacity, and battery voltage. 

With that having been said, for two batteries of the same chemistry, the larger one will have longer battery life. This is because the larger battery will be able to hold more charge. But this is where the correlation ends. A larger battery does not provide more volts or amps to the camera.  

What Hurts Battery Life?

Depending on the type of battery, there are different factors that may impact the battery life. But the most significant factors are common to all the battery types. Here are some factors that negatively impact the battery life of a camera. 

Slow Internet Connection Speeds

A wireless security camera spends a lot of its energy budget storing and sending data. However, if the internet connection is slow, the camera will spend more time sending the data and will have to store it for longer. This will result in battery drainage regardless of the kind of battery there is inside the camera. 

Extreme Heat and Cold

Batteries generate electrical power via chemical reactions that take place inside the battery. These chemical reactions are temperature-dependent. Most battery manufacturers recommend these batteries to be used and charged at room temperature. Operating at much higher or much lower temperatures can significantly decrease the battery life. 

Weak Signal Strengths Between Device and WiFi Network

If the WiFi device is not close to the camera or if there are a lot of concrete walls between the WiFi and the camera, the result will be similar to that of slow internet speeds. The camera will have trouble transferring data and may have to store it for longer. The result would be the drainage of the battery at a much faster rate. 

Ways You Can Save Battery Life

Place a Light Near the Camera 

If your camera is infrared enabled, it probably has significantly shorter battery life. Night vision takes a lot of power. If you get a camera without night vision, it will probably have much longer battery life. You may place a light near the camera, so your camera never has to use its night vision. Either way, place a light near the camera so it can see at night without using extra power. 

Recharge Only When the Battery Runs Out 

If you recharge the battery only when it is completely drained, you will have to charge it less often. This would increase the battery life. 

Get a Stable Internet Connection 

A slow internet connection can result in a lot of batter drainage. In order to save power, get a stable connection. 

Place Your WiFi Closer 

Place your wife closer to the camera or place the camera closer to the WiFi so that the signal from the WiFi does not have to pass through a lot of walls. 

Battery life depends on several factors, some of which can be exploited to increase the battery life. Now that you know what causes different types of batteries to age, you can actively keep your battery from self-discharging.
