| EEVblog #751 - How To Debunk A Product (The Batteriser) |

I had a 1GB MPIO MP3 player that was nearly hopeless on AAA NiMH batteries so I ended up connecting it to an external AA battery to get a day out of the thing. I never measured what its cut-off voltage was but I would guess it was not very far down the NiMH discharge curve. |

One case where a large percentage of the battery capacity is wasted is in high drain devices like digital cameras. But such a booster will not be useful for that and the only way to use the remaining capacity is in lower drain devices like clocks. |

The 800% figure could hold up when taking a medium current device like a Xbox-Controller and one of these ultra-cheap Alkalines. In my experience, the cheap ones can cause the controller to fail at 1,3V Open-Loop Cell-Voltage. Good batteries and Ni-Mh Accumulators can power my controller down to 1,1V or even 0,9V (accumulator). What is missing in the video: Discharging an Alkaline right down to the point where it is completely empty highly increases the chance that it starts leaking. Try leaving a fresh battery inside a powered flashlight (the old ones without LEDs) for 3 or 4 days and they most likely start spilling their guts. The only place where I can see a real use for these devices: LED Flashlights that use only a resistor with the LED in series, instead of a proper Driver-IC (Which I assume is true for about 90% of all available types of LED-Flashlights). With the Batteriser, there would be no fading of the light-intensity when the battery-voltage drops. Only problem there: Most of these LED-Lamps I know use one or several AAA-Batteries. So in conclusion, it is, and probably will be for quite some time, cheaper, greener and generally better to just use Accumulators, like I'm doing for about 10 years now :) |

Maybe the Batteriser founder has simply misunderstood the expert he asked for a statement... Dr. Kiumars Parvin of San Jose State University is quoted to have said: “We tested the Batteriser sleeve in our lab and we confirmed that the Batteriser taps into 80 percent of energy that is usually thrown away,”. He did not say "... taps into the 80 percent of energy that is usually thrown away." He probably mant to say - or maybe even said, and is quoted incorrectly: "... taps into 80 percent of the energy that is usually thrown away." That would actually make sense, taking the converter losses and some remaining unusable capacity at <0.6V into account. Just omitting a single word makes that quote so much more effective in advertising ::) |

You're not supposed to put this on a new battery and use it all the time, you're supposed to put it on a 'dead' battery so you can keep on using it a bit longer. --- End quote --- Read their website, that is not what they imply. Use on new batteries seems the primary usage scenario. |
