So 4 AAA's going your way. --- End quote --- Thanks. One will get damaged with wires soldered on it for testing, so that leaves 3 for a product. |

When the product stops, low batt comes on etc I have my time (and video proof). --- End quote --- Right, but that's no fun :) I already learned a lot by building it and setup the automated measuring procedure. For the characteristic curves I checked my HM8012 multimeter and the uCurrent with this nice device: http://www.voltagestandard.com/DMMCheck_Plus.html (with the nice case you can see at the bottom, but an older version, without the AC/DC switch, just DC). Cross checked with a BM257s multimeter and all results are very well below 1%. And the ADG608 switch is really good, no difference when measuring the voltage at an input and when switched to an output. |

But looks like they removed the feature in later software? https://www.picotech.com/support/topic6815.html :o Maybe the Picolog software supports your Picoscope. But they have a nice and documented API, it is easy to write some data logging program for it. |

There could still be 10%-20% left in there. --- End quote --- Which is the ballpark we all expect the Batteriser to improve things by on most modern products, at best. If that turns out to be the case then it's a dead duck product. No one is going to give up the functionality of their battery gauge for 10-20% extra battery life and have the thing just die on them. |

One of Batteroo principal claims is that they can be used with "dead" batteries. I think we need to do tests starting with "dead" batteries and show the public how much longer things will run. eg. A LED torch might start up again with a Batteriser but I don't think it'll run for more than 20-30 seconds. That's a looooong way off the 80% that Bob claims it will do. :-// This would make for good, simple to understand video footage ("Batteroo lies!"). |
