how long will a 12v battery last with an inverter

- nominal voltage vs actual voltage: nominal voltage of the lead-acid batteries is 12V, but the actual voltage of fully or almost fully charged lead-acid battery is ~13.5 volts. When calculating actual runtimes, constant power discharge tables are of great help, but even without them, one can approximate runtime using a few assumptions... Just be sure not to forget that these ARE the assumptions, while the constant power discharge tables are official data given by the battery manufacturer (and that may change without prior notice!). Hooking the fan up to a larger battery pack isn’t an issue as long as you get the voltage correct. If the battery is being discharged faster, its actual capacity decreases, and when the lead-acid battery is being discharged for 1h, the actual capacity is around 50-72% of nominal capacity, battery dependent.
