John,
I've never seen this happen with Lithium Ion batteries but I
*have * had this happen with Metal Hydride batteries. I have a few
"sets" of AA MH batteries that I used for a year that will no longer
hold much of a charge (I believe the brand is Mempro). They will work
alright in a low drain item like a flash light but will barely power-up
my older Olympus UZ digital camera.

Subject: [OM] rechargable lithium ion batteries
I normally use two rechargable 3 volt lithium ion battery packs in an OM
flash gun with my E510. The flash is a dedicated gun for the E series.
When the flash has not been used for several days the battery packs do
not bring the flash gun to life. If I change over to four Ultra Duracell
1.5 volt batteries the gun springs to life. If I then change yet again
to the LI battery packs the flash springs to life immediately. It is
almost as if the flash needs to be initially energized with the Duracell
batteries before the LI packs become operative.
The LI packs are only a matter of a few weeks old, are fully charged and
the connector points on both packs and in the camera are clean.
When I start off from "cold" with the LI packs installed in the flash
gun, the gun still remains inoperative even if I jiggle the packs
slightly or apply a little pressure to the slide mount cover on the
flash gun casing so as to effect a "better" contact between the
terminals on the packs and in the camera.
Does anyone have any idea about what might be ailing my flash gun and /
or LI battery packs?
