How to power led strip light with battery?

Use a battery instead of AC power outlets for your strips. You won’t always have access to an electrical outlet to power your strip lights. In situations where you need a battery, it’s handy.

Can I use a battery to light an LED

Batteries are used in flashlights, cars, and other electronic devices. LED lights are no different. In fact, a battery is an excellent power source for LED strips.

Why should you use a battery to power an LED strip?

There are some places where it is difficult to access AC220V power. Like basements, cabinets, and closets under sinks, drawers, and garages. We can’t find a socket because they are not easy to access. Some LED lights can use batteries. Just like a flashlight, camping light, some decor light, and gift lights. That is why we need to use batteries as power for our LED strip light. And sometimes, we need to make demo kits for our clients to show our LED strip lights.

How to Select a Battery for Strip Lighting

Here are some tips for choosing a battery for strip lighting: consider the size of battery, the type of battery, and the wattage of the battery.

  • Voltage

  • capacity

  • connectivity

Voltage: When you’re choosing a battery, make sure to use one that doesn’t have more voltage than your strip needs. Connecting a 12V strip to a battery that produces more than 12 volts can damage or destroy it.
Capacity: A battery’s capacity is a measure of how much power it can hold. It’s measured in watts-hours (Wh) or milliamp-hours (mAh). The higher a battery’s capacity value in mAh, the longer it will last.
Connectivity: You also need to make sure the connectors on your battery pack and LED strips match. Most battery packs have open wiring or DC connectors. LED strips have open wires, copper pads, or DC plugs.

What type of battery should I use to power my LED strip light?

In general, there are three kinds of batteries you can use.

  •   1.5V AA battery.
  •   3.7V rechargeable battery
  •  DC12V battery

1.5v AAA or AA alkaline batteries:

The strip light we use requires a DC12V power source. The most available batteries on the market are AAA and AA alkaline batteries, which produce the same 1.5-volt output when fully charged. So we need to connect eight AA batteries in series to make a DC12V power supply. You can see a battery box in the market as the following figure shows:

3.7V rechargeable battery:

Many products use rechargeable batteries. As you know, these batteries can be used in camping lanterns, headlamps, flashlights, book lights, work lights, brake lights, and night lights. These lights are easy to take away. Let’s see how we can use rechargeable batteries in LED strip lights.

For example, 3.7V*3pcs=11.1V. We also can use a 3pcs rechargeable battery in series to make power.

For unlimited power on the go, you can’t beat a 12V Lithium battery. Because of its size, a 20,000 mAh battery provides the most capacity compared to other types of batteries. It is rechargeable, so you can use it over and over again. It’s rechargeable and can be used again and again, which makes it perfect for applications like powering an automobile’s electronics or running a laptop computer.

How do I connect the LED strip to the battery?

Batteries have positive and negative poles. Connect the LED strip light’s positive pole to the battery’s positive terminal, and connect its negative pole to the battery’s negative terminal. When you don’t want to use your LED strip light, flip the switch on the battery to turn off the power.

How Long Do LED Strips Last?

A larger battery will power an LED strip light longer than a smaller one. When you’re using the same battery, a smaller power LED strip light will consume more energy. It’s just like our mobile phones. When we are using new phones, their batteries can last for two days. After we use them for a year, they only last one day. The same thing happens with LED strip light batteries; the new ones last longer and older ones are used up faster.

How to Increase Battery Life ?

How to Increase Battery Life

Batteries can only power your devices for so long before they lose their charge. This is called battery drain. You have to buy new batteries or recharge the ones you have, in order to use your device for an extended period of time. There are some easy steps you can take to extend the life of your batteries.

  • Add a Switch
  • Add a Dimmer
  • Decrease the Lighting

Add A switch:

A switch is a simple device that you can use to turn a circuit’s flow of electricity on and off. Some LED-to-battery connections use switches, too. When you’re not using your LED lights, turning them off can save you a lot of energy by preserving your battery’s life. Because LEDs are already energy-efficient devices, adding a means to turn the power off only makes sense!

Add A Dimmer:

The more LEDs in use, the more power your battery will consume. For example, a single coin cell battery can power an LED bulb for 11 hours; however, when you add another bulb to the circuit, your battery’s life decreases significantly to just over 5 hours. To offset unnecessary power consumption, decrease the number of LEDs in use to meet your ideal battery life.

Conclusion:

Batteries are necessary for many electrical devices, including LED strip lights. To ensure your LED strip lights perform as intended, you need to match the correct battery specifications to your lighting project.
