Battery Run-Time Calculation

First, Calculate Total Power Consumption Wattage of the 12V DC LED Fixture:

    • Total Power Consumption (watts) = Power Consumption (watts/ft) x Length (ft)
    • For example, if the LED 12V DC Tape light runs 3 watts per ft and the project requires 16 ft of LED Tape Light, then the total power consumption is 3 watts x 16 ft = 48w
  1. Secondly, Calculate the Amp Power: 
    • Amp Power = Total Power Consumption (watts, calculated in step 1) / 12V DC
    • For example, the amp power of the 3 watts per ft 12V DC LED Tape Light is 48 watts ÷ 12V DC = 4 Amps
  2. Finally, Calculate the Runtime:
    • Total Runtime = Amp Hour (Ah) of the Battery ÷ Amps (calculated in step 2)
    • The total runtime of STDC12-3.2 battery with 3 watts per ft 12V DC LED Tape Light is 3.2 Amp Hour ÷ 4 Amps = 0.2 Hour
