What to consider when choosing a battery to power LED lighting

Home > News > Products > The Best Batteries to Power LED Lights

LED lights have become a popular choice for efficient and reliable lighting solutions due to their energy efficiency and long lifespan. From providing safe working conditions on construction sites to adding lure to advertising displays, LED’s flexibility is being harnessed by professionals worldwide. To power these lights optimally, selecting the right battery is crucial. Below we’ll explore the advantages of using Tracer Power 12V rechargeable lithium batteries to power LED applications.

What kind of battery do I need for LED lights?

LED lights require a stable and consistent power supply to operate efficiently. When choosing a battery for LED lights, consider the following factors:
Energy Density- Opt for batteries with high energy density, as they can store more energy in a smaller and lighter package. Making them suitable for portable and space-constrained LED lighting applications.
Lifespan- Consider the battery’s lifespan and the number of charge-discharge cycles it can endure before its capacity significantly degrades. Longer-lasting batteries will result in reduced maintenance and replacement costs over time.
Self-Discharge Rate– Look for batteries with a low self-discharge rate, which means they can retain their charge for longer periods without frequent recharging. This feature is essential for LED lights used in intermittent use scenarios.

While other batteries like lead-acid, NiMH, and alkaline may suit specific applications, Tracer Power lithium batteries outshine them with their exceptional energy density, lifespan, and self-discharge rate.

How long will a 12-volt battery run 12V LED lights?

To determine the runtime of 12V LED lights with a 12V battery, divide the battery’s capacity (Ah) by the total current draw of the LEDs (in amps). For example, Tracer Power 12V 10Ah battery can power LED lights with a current draw of 0.5A for around 20 hours.

Powering Lights with Lithium Polymer (LiPo), Lithium-Ion (Li-Ion) or Lithium Iron Phosphate (LiFePO4)?

Lithium Polymer (LiPo): LiPo batteries have a higher energy density, meaning they can store more energy in a smaller and lighter package. This makes them suitable for applications where weight and size are critical factors.

Lithium Iron Phosphate (LiFePO4): LiFePO4 batteries have a lower energy density compared to LiPo batteries but they compensate with an increased charge cycle life. LiFePO4 can be charged and discharged 4x more then LiPo making them more cost effective over a longer period of time.

LiFePO4 also have a flatter discharge curve meaning they will deliver a more consistent voltage supply, resulting in more stable and constant brightness. As a result, the LED lights will remain brighter for a more extended period before the battery’s voltage drops significantly enough to affect their performance.

Lithium-Ion (Li-Ion) sits in the middle for most characteristics when comparing it with LiPo & LiFePO4. Lightweight compared to LiFePO4 and an increase in charge cycles compared to LiPo. Tracer supplies these in Module/Carry Case Kit formats. ranging from 12V 50Ah-150Ah.

3 Steps to work out how many LED’s a 12V battery can power?

How many LEDs can I run off a 12V battery?

The number of LEDs you can run off a 12V battery depends on the battery’s capacity (Ah) and the individual LED’s current draw (in amps).
Step 1) Calculate the total current draw of the LEDs: Find out the current draw of each LED Light/LED Strip in amperes (A). If you have multiple LED Lights/LED Strips, add up their individual current draws to get the total current draw.
Step 2) Check the capacity of the 12V battery: The capacity of the battery is usually measured in ampere-hours (Ah) and indicates the amount of charge it can hold. For example, if you have a 12V battery with a capacity of 10Ah, it can theoretically deliver 10 amps of current for one hour or 1 amp for ten hours.
Step 3) Divide the battery capacity by the total current draw: To estimate the number of LEDs the battery can power, divide the battery capacity (in ampere-hours) by the total current draw of the LEDs (in amperes). If the final answer is a positive figure the battery can power that amount of LEDs. The result will give you an approximate runtime in hours.

How to convert Watts (W) to Amps (A)

To convert watts into amps, you need to know the voltage of the circuit or device you are working with. The formula to convert watts to amps is:
Amps (A) = Watts (W) ÷ Voltage (V)

5W LED = 5÷12=0.41A

Work out run time:
10Ah ÷ 0.41 = 24 Hrs

If the battery was to power 3x the lights
10 ÷ (0.41+0.41+0.41) = 8hrs

Please Note: The cut off voltage of the Equipment may impact the run time depending on the chemistry discharge curve characteristics.
