I have assembled a 300 units of 3650 LED lights which draws a total power of roughly 6 Amps (130Watts) and I want to power it using a 12V 18Ah Lead Acid Battery.
My question is, how long or how many hours the assembled light will last before the battery gets fully discharged?
Is there a certain formula that I can use to get the total hours consumed?
Many thanks in advance for your help.
