Battery capacity plays a pivotal role in determining how long it can discharge an equivalent amount of energy. Measured in amp-hours (Ah) or watt-hours (Wh), the capacity indicates how much energy the battery can hold. Larger capacity batteries typically provide extended discharge times. For example, a 100Ah battery rated at 12 volts can deliver 1,200 watt-hours of energy.

When analyzing a battery’s runtime, one must consider its efficiency. Not all energy stored is available for use; some energy may be lost due to heat and internal resistances. Optimally, using a high-quality battery with lower internal resistance, like lithium-ion types, allows for better efficiency and thus, longer discharge duration.

In real-world applications, such as powering electric vehicles, understanding battery capacity is critical. An electric vehicle may have a 75 kWh battery, enabling a range of about 300 miles on a single charge, contingent upon driving conditions and the electrical load. Discharge calculations reveal how different driving scenarios (urban vs. highway) can significantly fluctuate the time it takes for the energy to deplete.

2. POWER DRAW OF APPLIANCES

The power consumption of connected devices is equally crucial in estimating how long a battery can supply power. Determining the total wattage of appliances being powered provides insight into discharge timing.
