Web4 mrt. 2024 · To measure a battery's capacity, use the following methods: Connect the battery to a constant current load I. Measure the time T it takes to discharge the battery to a certain voltage. Calculate the capacity in amp-hours: Q = I×T. Or: Do the same, but use a constant power load P. Calculate the capacity in watt-hours: Q = P×T.
WebBased on this, we can now calculate how long will a 200 Ah battery be able to power an 800 W 240 V air conditioner: 200 Ah Battery Life = 200 Ah / 3.33 A = 60 hours. As we can see, because the amp draw is halved, the battery life is increased. That’s because an 800 W air conditioner on 240V requires fewer amps than an air conditioner on 120V.
