Important Factors That Can Affect Your Results
While the calculator provides a theoretical estimate, real-world conditions can influence actual battery performance. Temperature plays a major role, as batteries generally perform better in moderate climates and lose capacity in extreme cold or heat. Chemical reactions inside the battery slow down in cold weather, reducing available amp-hours, while excessive heat can accelerate degradation and shorten overall battery life.
Battery age and cycle count also impact results. Older batteries may not hold their full rated capacity due to internal wear and reduced efficiency. Additionally, the rate of discharge matters; discharging a battery very quickly can yield less total energy than a slower discharge due to internal resistance losses, a phenomenon often described by Peukert’s Law in lead-acid batteries.
System inefficiencies, such as voltage drops in cables or losses in inverters, must also be considered. If you are converting DC battery power to AC, your inverter efficiency rating should be factored into your device power input to get a more accurate runtime.
