AA Li-ion (dumb cells) from Energiser RECHARGEABLE and 2 other brands in the charger that was included with the batteries (and 2 alternate Li-ion chargers).
1 weak after a "full charge" (charging LED out), and multiple brand Cameras (set to Li-ion) say 1/2 charge or less.
The non-rechargeable "Lithium" battery has Excellent shelf life.
1 set of with the problem I would have said, bad part. 6 combinations of cells, chargers and Cameras.. 
YMMV |
Sorry that you had such bad experience, but that sort of anecdotal evidence is really not a basis to disregard scientific facts concerning the technology. In fact, since you did not mention specific voltages or other actual measured data, there is no real way to know where things went wrong in your anecdote.
The Wikipedia article that I cited has 71 references to back up statements made in the article, so claiming the article is wrong about the very low self discharge rate of Lithium chemistry cells is arguing against a very large weight of scientific evidence. Maybe if you read the article and the cited references you would be able to understand what went wrong in your anecdote?
FWIW, I have been using unprotected "dumb" Lithium cells in electric flying model aircraft and other devices for several years, and have never ever seen any easily measurable self discharge. Lithium cells certainly are not perfect, but self discharge is not one of their imperfections and is orders of magnitude better than Nickel based cells.
