In this case, Dave did the proper thing and tested a couple of devices and showed that they do not stop working at 1.35 V. Problem is that Batteroo then says Dave performed the test the wrong way... Unless you yourself can tell who's right it comes down to trust.
Then Batteroo finally came out and admitted that it was actually 1.1V under load they talking about, thus proving I am completely right. After 5 years of developing this and never once mentioning it in the patent or their website or any promo material, press, or videos etc, they finally admitted it. But it only lasted a day or two before they removed the mention of 1.1V under load form their website.
Luckily I had it screen captured:
Everyone should keep reposting this everywhere!
It blows their claim completely out of the water, and it's why they had to change the wording in their promo video too, their logo etc.
They know that once they admitted that it's trivial for anyone to look a battery datasheet and see how much energy is really wasted in the battery at the 1.1V cutoff they have admitted. That puts their product, buy their own admission!, in the territory of only applying to a smaller number of badly designed products. No wonder they removed it.
The only thing they had left to defend themselves was the ridiculous and embarrassing claim that I did the testing wrong.
I'm in two minds whether to do another video busting absolutely everything they have done and have said, and changed etc. But I know it won't amount to a hill of beans.
Should I bother?
