If a mAh rating is used then a say 6Ah cell will give t = Ah/I = 6/3.3 or 6/2.5 = 1.8 hours or 2.4 hours at the current extremes, and in practice somewhere in between. The same cell will probably be rated as Wh = Ah x 3.6V = 6 x 3.6 = 21.6 Wh. Run time = Wh/P = 21.6/10 = 2.6 hours. 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. my lil players daycare bismarck nd
