Calculator for battery run time for Lead Acids batteries

This is a simplified battery capacity calculator for Lead acid batteries is using the Peukert's law. In essence this calculator is using Peukert's constant k=1.2 (as be best valie is around 1.1 and the worst 1.3). I'm not taking in the account Lead Acid battery need to stay above 10% of i't rated capacity and assuming we are draining battery to 0. You need to know: a. Time needed to run your loads in hours;  b. Load currents in Amps.

Run time for lead acid batteries I (load current), (A)
Battery capacity C, (Ah)
