--- Quote from: dcac on December 22, 2016, 07:36:43 pm ---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. --- End quote --- I think the official measurement given was "half a bee's dick", IIRC. |

Excellent thread guys. :-+ I don't think the minute weight of the sleeve would make a hell of a difference personally and if you were going to start factoring in those minuscule details then you may also want to consider that the moving parts of the train over time will probably free up with wear, I wouldn't worry about it at this point in time. |

It is important to verify experiments. The Batteroo sleeve was the other one I have, so no faulty sleeve, no faulty battery. Time confirmed, 61 minutes this time. --- End quote --- We should include this measurement in the google doc too, just to keep the record. |

Pretty please, with cherries on top, add labels to the legends (or whatever they are) on these graphs. I'm having flashbacks of college & failing grades on lab reports for not having everything labeled correctly.[emoji52] Sent from my SM-G900V using Tapatalk |

But doesn't matter much, the interesting result is that the advantage is 3% instead of 300%. --- End quote --- I understand your argument. I am just curious whether that 3% extra turns out to be 0% in real term. I think your test results should be indicative for all direct battery powered motorized devices and "toys", including the monkey ... The other device types of interest are those with built-in DC-DC convertors and those with pulsed power consumption. The interest is mainly on checking all different predictions made throughout the 300+ pages. --- End quote --- Yes, I can almost guarantee that if the bare battery from the test with bare battery had been left to rest for an hour and reinserted again bare, without the batteroo, it would have run for at least as long, probably longer again than it did with the batteroo on. As a kid that was always my method with dead batteries, swap them back and forth giving them time to rest and the toy would always run again for a good while. You'd actually get a better increase in life from the "dead" battery by biting it hard and reinserting it than by putting a batteroo sleeve over it. Seriously. --- End quote --- I remember back when I was a kid, someone 'taught' me to put dead batteries out in bright daylight and they'll recover some 'energy' from the sun... I wonder if it's just the natural battery regeneration after all... Or maybe there's some truth in that the heat affects the chemical inside and it 'rearranges' to give higher recovered voltage or something? :-// At any rate, Is that train a pure resistive load ie. no regulation circuit at all? Also I agree, should do the test with the parameter of 'reinserting' 1) Test A without batteriser until train stops, keep battery aside and after a while (fixed time) and maybe some treatment(biting, sun-drying? :-DD) reinsert and continue experiment 2) Test B with batteriser, same as above, reinsert battery into batteriser and re-test. 3) Test C without batteriser, reinsert into batteriser and re-test 4) Test D with batteriser, reinsert without sleeve back and re-test Cheers :popcorn: |
