It would be just great to be able to measure how much more energy they can get more from a battery with a Batteriser: Take a fresh set of batteries and discharge the batteries with constant power until the battery voltage drops to specific cut-off voltage, for example 1V. Now, attach the Batteriser to the battery and measure how much more energy you can squeeze from the battery until the output voltage of the Batteriser drops below that same cut-off voltage. You may also want to repeat the test with a constant current for the comparison purposes.
Yep, this will be one of the standard test I'll be doing when I get my hands on some.
And a parametric graph as well based on various constant current and constant wattages (close enough to how the majority of electronics products will behave)
Sadly though it would take far too long to do this for light loads. But even Batteroo have (now, not initially) freely admitted that it's not going to perform well on low current drain devices.
Although I would encourage Wayne to actually test these things properly. With a conversion efficiency graph for different loads, and controlled product testing.No need.
His "two identical flashlights" test is enough - so long as he's honest about the results.
If these are just a very limited batch of samples, they probably don't need the approval mark

Actually it may be best to use only one flashlight as you can be sure that the conditions do not vary. Take a set of fresh batteries, drain the batteries until the flashlight stops working or the light becomes very dim. Then attach the Batteriser to the batteries and measure how much longer the flashlight will work.

You can swap the two flashlights around if you don't believe that Batteriser always dies first.Take a set of fresh batteries, drain the batteries until the flashlight stops working or the light becomes very dim.

Most people will just put the thing onto the new batteries.
(who wants to carry the batterisers around in their pocket then fiddle around in the dark trying to fit them to a dead flashlight?)
There isn't a single engineer on the planet that even remotely doubts the Batteriser will "work" as a boost converter and give you 1.5V output from a "dead" or "used" battery.
Some of the things I am interested in include:
What is the standby current (as the Batteriser is always on).
If there are multiple Batterisers, do you end up with an audio frequency noise on the power to the device due to mixing of the switching noise.
If you are powering an AM radio and the Batteriser is switching at perhaps 1.5MHz, how does the radio behave?
What happens when one Batteriser shuts down - does it go open, or is there a forward biased diode junction from the flat battery?
Notice in the Aussie dude's pic, the packaging says Batteroo, whereas the Greek dude's says Batteriser. That makes very little sense to me.
When these parameters have been determined empirically, the model can be fitted to the measurements. Once the model has been tuned in the performance of the Batteroo with various loads can be predicted without having to wait for the batteries to discharge.

Both sets of casings say Batteriser, however, which does make sense if you buy my theory of these being assembled from pre-production prototypes

Bob explained this in an update. They have permission from their Lawyers/Energizer to ship some existign units with the Batteriser name on it. Some people will get Batteriser, some will get Batteroo.
Yep, but it's like the audiophool snake oil claim "you have the listen to it". With the Batteriser true believers it's "you have to try it in the product".
Either:
a) The batteries weren't nearly dead (in which case there wouldn't be a 'noticeable increase in brightness')
or
b) They didn't go for another hour.
...and
(c) What happened after an hour? You stopped the test because it was finished??
It could just be a really crap flashlight (say 2 AAs driving a white led with a Vf around 3V)
Wayne has said anyone is free to come over and do more extensive testing on them. If he was in Sydney I'd take him up on the offer. Although decent product testing will take many days work just for starters.
He has admitted he's not good with the complex characteristic testing of such things and graphing etc. But he will release all his basic product test results.
