That YouTube page also has a video of the Batteriser tested on flashlights. Check it out if interested.
This video and study published by Duracell claims that batteries thrown away on average have 67% capacity left. https://youtu.be/JglYXZgP740 .
Next point, this study by Dr. Rolfz in Switzerland claims that 10% of batteries thrown away contains 1.4v left when discarded. http://www2.ife.ee.ethz.ch/~rolfz/batak/ICBR2003_Zinniker.pdf This Swiss conference study is very interesting. The results show that the average battery in the test retained 33.3% of the battery's capacity...10% were considered "new" and it looks like over 60% had over half of the capacity. 30% of discarded batteries have 50% energy left in them...which is again a very significant point...this means if device could use the other 50%..., one can double the life of the battery.....The point that I want to pay more attention to is that the assumption is that Batteries would stop working at 0.9 volts...however with Batteriser we can draw the remaining power till around 0.6 volts which is gives additional life extension to the battery
Also interesting was their extrapolation that 20 million Swiss Francs (about $21.2 million USD) worth of battery value is thrown away every year in Switzerland!
The most important point from this article is that 10% of batteries had cut off voltage greater than 1.4 volts, which means that 1.5 billion batteries have greater than 1.4 cut off voltage. 1.4v is much higher than Batteriser’s patent claim of 1.3 to 1.35 volts cut off voltage...
