How Long Can LED Strip Lights Run While Maintaining Car Battery Health?
LED strip lights can run for approximately 8 to 10 hours on a car battery without significantly impacting battery health, assuming typical usage. The average car battery has a capacity of around 48 amp-hours, which means it can provide around 1 amp of current for 48 hours. Most LED strip lights consume between 0.2 to 0.5 amps per meter, so running about 5 meters of LED strip lights would typically draw around 1 to 2.5 amps. This indicates that the lights can safely operate for several hours without a full drain.
Several factors can influence the exact duration. The total length of the LED strip, the specific current draw of the lights, and the existing charge level of the car battery all play significant roles. For instance, if the LED lights consume 2 amps and you have a fully charged 48 amp-hour battery, continuous operation would deplete the battery in about 24 hours.
