My Eneloops are 07 and still fine I meant Energiser not everready, its too early for me.

Sanyo didn't need rocket scientists to claim a unique process, just a patent (which I assume the have). I'm using Eneloop and Kodak pre-charged. Can't see much difference, both are excellent at holding their charge. While I'm posting, will someone tell me how I can determine who owns or doesn't own a camera in this group.

LOL. > Sanyo didn't need rocket scientists to claim a unique process, just a > patent (which I assume the have). Getting a patent is easy. Defending it is the hard part. The cause of self-discharge in Ni-Cad and NiMH batteries has been well known since they were first invented--the plates swell and press against the separator. You can reduce the swelling by depositing less active material on the plates, but this reduces capacity. The goal in NiMH batteries was always higher capacity. Sanyo made a decision to reduce the capacity and decrease the self-discharge. I wonder if anyone is actually paying them royalties or licensing fees for this. > While I'm posting, will someone tell me how I can determine who owns or > doesn't own a camera in this group. A P&S or a D-SLR?

There are a number of fairly obvious fakes (if you read between the lines), but there is no way to really know for sure, so take *all* posts ( including mine ;) with a grain of salt. -- John "Assumption is the mother of all screw ups."
