Batteriser / Batteroo Toy Train Test

Full unedited test (in a single video shot) of the Batteriser / Batteroo AAA sleeve with a toy train. Footage sped up 10 times during the boring laps.
19:45 End of first test
31:51 End of second test

Result:
169 minutes and 508 laps without Batetriser
94 minutes and 351 laps with Batteriser
(31% less laps, and 44% less run time with the batteriser)

3 minutes and 10 extra laps on the "dead" battery with the Batteriser (Just under 2% extra life based on laps)
Not 200%, not 20%, a lousy 2%

Conclusion = The Batteriser FAILS on both metrics, on new batteries and on dead batteries. And it doesn't extract all the energy from a battery either.
