Iout =250mA @ Vout =1,5V at the load means you have : Iin=Iout*Vout/Vin *Eff = .25*1,5/1*0,88 = 330mA ... --- End quote --- Iin=Iout*Vout/Vin/Eff = .25*1,5/1/0,88 = 426mA I think at this current and state of discharge, the battery ESR has a significant impact. The AAA battery should be stopped working long before reaching 1 V discharge state. |

I realize this is a bit grasping at straws, but how much does the Batteriser weigh? and how much does the Toy train weigh? together with the AAA cell. A AAA cell weigh about 11.5g and I’m guessing the train except for the engine parts is mostly plastic but still not easy to judge it's weight. In any case the train with the added weight of the batteriser, even if it’s relatively small, would require more energy to move around. |
