how to power led strip light with batteries？

LED strips are flexible and versatile lighting products, but require a power supply to illuminate. What if you want to use the LED strips in a location where you don't have access to a power source or outlet? You may be wondering if there is any portable power solution!To get more news about Neon Signs supplier, you can visit htj-led.com official website.

In this article, we show you how to select and connect a rechargeable battery (or standard AA batteries) to an LED strip, and allow you to use your LED strips anywhere!

Could you power your led strips by battery instead?

LED strip lights can be powered by a battery, but you’ll likely need to rewire them. The most important thing is matching the voltage of the strip – too many volts will damage the strip. Too few, and it won’t work. A 3-meter strip will last around 20 hours if connected to 8 AA batteries.
The strip light we use is DC12V. The output of the battery is 1.5V. So we need to connect the battery in series. Then the output of the battery will be added up. 8pcs*1.5V=12V. So we need to use 8 pcs AA battery in series to make a DC12V power.

3V Coin Cell Battery

A 3V coin cell battery is a type of small, circular battery typically used to power small electronic devices such as watches, calculators, and remote controls. They are also known as button cell or coin cell batteries and are usually made of lithium, alkaline (manganese dioxide), or silver oxide. Coin cell batteries are designed to be used in devices that require a small, compact power source and are commonly used in devices that need to be powered for an extended period with minimal maintenance.

3.7V rechargeable battery

Rechargeable battery use in many products. As I know, battery can use in camping lanterns, headlamps, flashlights, book light, work lights, bake lights, night lights. This lights are easy to take away. Let’s see how we use this rechargeable battery in led strip light. 3.7V*3pcs=11.1V. We also can use 3pcs rechargeable battery in series to make a power.
9V Alkaline Battery

A 9V alkaline battery is a type of cylindrical battery commonly used to power small electronic devices such as smoke detectors, carbon monoxide detectors, and portable radios. These batteries are typically made of zinc-carbon or zinc-manganese dioxide and have a voltage of 9V.

Alkaline batteries are known for their high energy-to-weight ratio and can deliver a steady voltage for an extended period. 9V alkaline batteries are often used in devices that require a high current, as they can provide a large amount of power in a small, lightweight package. It is important to note that 9V alkaline batteries are not rechargeable and should be replaced when they no longer provide sufficient power.
Normally, this battery is bigger. We see this battery in our cars. And some night market will use this battery power the led light when they are doing business. And this battery is rechargeable. This battery can power any led light which input is DC12V. And because of the capacity of this battery is big, so this battery can use longer than AA battery and 3.7v rechargeable battery.

What batteries are best for LED lighting strips?
Among all the above batteries, I like 12V Rechargeable Lithium Battery the most as it provides 12V, the same as the LED strip. It is rechargeable, while it is more expensive. I won’t choose a 9V Alkaline Battery since the LED will not be fully lit. I won’t pick a 3V Coin Cell Battery, as it is difficult to link them together. Instead, I will select 1.5V AA/AAA Alkaline Battery or 3.7V Rechargeable Battery according to my different requirements. p.s.: If we decide 1.5V AA batteries, we need a battery box to connect eight batteries, since 1.5*8=12V is exactly the voltage of the LED strip. If we choose 3.7V batteries, we also require a battery box to connect three batteries because 3.7*3=11.1V, which is closest to the voltage of the 12V LED strip.
