To find out how long a car battery can power LED lights, use this formula: Duration (hours) = Battery Capacity (Ah) / LED Current (A). For example, a 45Ah battery powering a 0.5A LED bulb lasts for 90 hours (45Ah / 0.5A). This calculation effectively estimates how long your battery will last.
To calculate the duration, divide the battery capacity by the light’s current draw. In the example of a 10-watt LED, a car battery could power the lights for up to 57 hours (48 amp-hours divided by 0.83 amps). However, running the battery completely can damage it. Therefore, it is advisable to utilize only 50% of the battery’s capacity for safety.
This discussion highlights the energy efficiency of LED lights and the importance of understanding power consumption. Next, we will explore practical applications and safety measures when using a car battery to power LED lights, ensuring a reliable and safe experience.
