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. --- End quote --- Well, they will, but once they realise it's the Batteroo doing it they'll stop using them. Or just forget them and throw them away with the dead cells and not bother to replace them. I think it'll have a brief surge in sales if it ever makes it to the shelves of a supermarket but it'll be on the shelf end 'tat' display and, if the company survives, eventually end up being sold via direct marketing TV shopping channels. |

I'd like to see inside that MP3 player --- if you can find a datasheet for the DC-DC it uses, you can compare the stated Vi(min) to the observed results. --- Quote from: EEVblog on December 20, 2016, 11:47:30 am --- --- Quote from: Fungus on December 19, 2016, 12:46:40 pm ---If it cut out at 1.1V then it's not using all the battery.

--- Quote from: Fungus on December 20, 2016, 11:52:14 am ---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. --- End quote --- That is precisely why I have this test as part of my spreadsheet. It's done in a controlled manor so you can easily get a direct "extra run time" percentage from the "dead" battery. |

I don't know if you can regard the claims in the Batteriser Twins commercial that was mentioned in an earlier thread as an official Batteroo statement, but they make a very simple claim that should be easy to test. https://www.eevblog.com/forum/blog/eevblog-751-how-to-debunk-a-product-(the-batteriser)/msg1093066/#msg1093066 "Guaranteed to increase battery life by at least two times, because two is better then one" |

Who sells those AAA to AA battery adapters in Sydney? I thought Jaycar used to have them, but can't find on their website. |
