Anyone looking to enhance the security and safety of their homes will be at least a bit familiar with motion detecting lights. These handy lights help with protecting the external parts of the home by flooding lights the moment it detects any form of motion. A motion activated light helps to keep perpetrators from getting near their target because they cannot rely on the cover of darkness to conceal their presence.

Flood lights are also a great security measure for homeowners who arrive late at night. Many attackers hide behind the shadows and wait for their victims to come home. As soon as residents walk up dark driveways or even front porches, they take the opportunity to grab their victims. A motion sensor light brightens dark corners, revealing strangers and would-be attackers.

However, the concern of many homeowners is how these devices work through the night. Simple research will show that there are three common kinds of motion activated lights: solar powered, battery operated, and those that use electricity. These three kinds all have their pros and cons, but many find that battery-powered sensors are very dependable.

Do Motion Sensor Lights Have Batteries?

No. Not all types of motion activated lights use a battery as their power source. Only two types usually include batteries: solar powered and, well, battery-powered sensors. Those that run on electricity do not contain batteries as they are connected to a different power source and that is more than enough to keep them operating.

What Is The Difference Between Solar Power Batteries And Regular Batteries?

When shopping for a new security light consumers will often encounter different wireless options. These two are solar powered and battery powered motion activated lights. If these devices both use batteries, what sets them apart?

To make a better purchasing decision it is important to compare these two types of devices. Given that you have opted out of a sensor that requires wiring and electricity to function, here’s what you need to know about motion detecting lights that have batteries:

Solar Powered Lights

These lights come with a solar panel, which also serves as a protective hood over the lights. This kind of device harnesses the power of the sun to recharge the batteries that it uses for power. Normally, the batteries that come with solar powered motion activated lights are permanently attached to the device. This is because the battery charges itself, which eliminates the need to change them when they are low on power.

This is an eco-friendly option, but there are a few problems with batteries that are charged by the sun. First of all, when the weather turns gloomy the batteries will not properly charge and the power may not be enough to keep the device active through the night. This can pose a serious security risk. Another issue is the fact that the batteries are attached to the device. This means that when the battery malfunctions the whole system needs replacing, which is more expensive than getting a fresh set of batteries.

Battery Powered Lights

These motion sensing lights require the use of a few batteries to function. Many of these lights have a battery detector to inform homeowners when the battery is low in power so that they can quickly change them for a fresh set. These are also wireless and relatively easy to install on any wall. They are usually waterproof and are less likely to short-circuit because of the lack of exposed wires.

It is advisable to invest in rechargeable batteries and always have a set that is fully charged on hand to make battery replacement easier, cheaper, and more convenient. The downside to this is when they start to run out of power, the lights are no longer as bright. Frequent battery changes can be a hassle, but gloomy skies and power outages aren’t an issue with this kind of security light.


Do motion sensor lights have batteries? No, not all of them do. Those that have batteries are easier to install and manage because no wires are involved. These lights are also smaller than those that have wires, which means they can blend in with your home’s design very well. Battery or no battery, having at least one motion-activated light at home is a great way to keep everyone safe from attackers lurking in the dark.
