Batteriser: legit or scam?

[ALIVE]

One way they could get those numbers:
1) Put the batteries into a high-drain device like a fancy digital clock.
2) Once it's saying that they're dead, remove them and Batterise them. They will indeed have a lot of remaining chemical energy stored in them, but the internal resistance versus the high drain current results in a high internal voltage drop.
3) Put the Batterised batteries into a low-drain device like a clock or remote control.
4) The low-drain device runs for a darn long time. *
5) Ignore the fact that it would also run for a darn long time without the Batteriser on it.
6) Find a marketer with really lousy ethics.



Back when they burned through AA alkalines like crazy at work using them on digital cameras, I'd gladly take the "dead" ones for my atomic-radio-controlled clock at home, if for no other reason than to keep them out of the trash a little while longer for whatever that's worth. They'd run it for several months because of its low drain current.
I did finally introduce them to the wonderful world of low-self-discharge NiMH AAs, so my supply of alkalines stopped. Eneloop time.

hight power is the worse scenario
because of the chemistry of the battery is not only the voltage thats goes down but also the capacity

so there is no way to get the 800% scenario they are saying

also low current draw is the worse for them because the converter will consume power so it will reduce the life

so we start from a dc-dc can help to get more life
and we end up nope practically it wont. lol
