Ellis Gibson (B.Sc. in Mechanical Engineering) A 3-amp load drains a 12v battery based on its amp-hour (Ah) capacity. For example, a typical car battery with 50 Ah delivers 3 amps for about 16.7 hours (50 Ah ÷ 3 A). Higher discharge rates can lower actual capacity, causing quicker drain. Consider the battery type and its discharge rate for accuracy. Using … Read more
A standard car battery has about 60 amp-hours. With a 25-amp draw, it will drain in roughly 2.4 hours (60 Ah / 25 A). Higher amp draws lead to quicker depletion. To protect battery lifespan, keep the draw below 50 milliamps. This helps prevent battery damage from excessive discharge. However, real-world conditions often affect this … Read more
An 18W LED light draws about 1.5 amps from a 12V battery. A fully charged 12V 10Ah battery can power it for roughly 6.67 hours. Factors like battery health and efficiency can change this time. Always consider all devices using power to avoid unnecessary battery drainage. Next, divide the battery’s capacity by the current draw … Read more
