It can have a nominal capacity of 500 mAh. If you need a reliable and long-lasting battery for your devices, then a 9V alkaline battery is perfect. The alkaline electrolyte is a mixture of potassium hydroxide and sodium hydroxide, both highly corrosive.ĩV alkaline batteries are also known for their long shelf life they can last up to 10 years when stored properly. 9V Alkaline BatteryĪ 9V alkaline battery is a battery that uses an alkaline electrolyte to produce a voltage of 9 volts.

It is made up of two or more cells that are connected in series or parallel. 3.7V rechargeable batteryĪ 3.7V rechargeable battery is a battery that can be recharged and used multiple times. Multiple batteries can be installed in one battery box, connected in series.
Battery boxĪ battery case is an excellent option if you need to connect multiple AA/AAA batteries. However, the capacity of AA batteries can be as high as 2400mAh. Alkaline batteries have a longer shelf life than other types of batteries, making them a good choice for devices that are not used frequently.ĭue to its small size, the capacity of the AAA battery is only 1000mAh. These batteries are often used in flashlights, remote controls, and other small electronics. 1.5V AA/AAA Alkaline batteryġ.5V AA AAA Alkaline batteries are common in many electronic devices. The amount of electrical current a coin cell battery can produce is determined by its size.Ĭoin cell batteries are typically made of lithium or zinc-carbon, although other materials such as silver-oxide or mercury-oxide can also be used.Ĭoin cells can only supply 3 volts at 220mAh, enough to light one to a few LEDs for a few hours. When the battery is used, the cathode and anode react with the electrolyte to create an electrical current. Coin cell batteries get their name from their size and shape, similar to a coin.Ĭoin cell batteries are made up of two electrodes, a positive electrode (cathode) and a negative electrode (anode), separated by an electrolyte. These batteries are also known as button cells or watch batteries. Coin cell batteryĪ coin cell battery is a small, cylindrical battery often used in small electronic devices such as watches and calculators. Common batteries generally include Coin cells, alkalines, and lithium batteries. There are a variety of batteries that can be used to power LED strips, each with a specific role. What batteries can be used to power LED strip lights? LED strips generally have open wires or DC connectors. A battery pack has open wires or DC connectors as its output terminals. Connecting the batteryĪnother thing is you need to make sure your battery and LED strip connectors are compatible. The result is the expected operating hours of the battery. Below are the mAh values of some standard batteries.įinally, you divide the battery’s mAh value by the LED strip’s mA value. You can find the mAh value on the battery. Then you multiply A by 1000 to convert it to mA. Then divide the total power by the voltage to get the total current A. You can quickly learn from the label of the LED strip that the power of one meter of LED strip, the total power is the power of 1 meter multiplied by the total length.

You may have a question, how to calculate how long a fully charged battery can be used to light up an LED strip?įirst, you need to know the total power of the LED strip.
This value indicates the hours the battery can deliver a specific amount of current (mA) or power (W) before it runs out of charge. Calculating power capacityīattery capacity is usually measured in milliamp hours, abbreviated as mAh, or watt-hours, abbreviated as Wh. And for 24V LED strips, you can connect 2 pcs 12V batteries in series, because 12V * 2 = 24V. The output voltage of a single battery may not reach 12V or 24V, and you can connect multiple batteries in series to get the voltage required by the LED strip.įor example, for a 12V LED strip, you need 8 pcs 1.5V AA batteries connected in series (1.5V * 8 = 12V). Otherwise, it will permanently damage the LED strip.
You need to ensure that your battery’s output voltage cannot exceed the working voltage of the LED strip. You must focus on the output voltage, power capacity, and connection. How to choose a battery for LED strip lights?Ĭhoosing a battery for an LED strip is very simple. Many of our sample display boxes are battery-powered so that we can display samples to our customers anytime, anywhere. But you can easily carry the battery with you. If you want to go camping outdoors, you can’t find power. The batteries are portable, so you can take them wherever you go.
Why do I need to use a battery to power LED strip lights? However, rechargeable batteries are recommended since they last longer and save energy. Yes, you can use any battery for lighting up LED strips. 17 Conclusion Can I light up LED strip lights with batteries?
