A couple years ago I started with Energizer and Duracell rechargeables, but less than 6months later I found that they wouldn't hold a charge. I then found the Eneloop brand and purchased some of the early version white Eneloops. Much better, but I found that they discharged quite a bit after sitting around for more than a couple weeks. Finally, I discovered the 2400mAh Eneloop Sanyo XX, which have been great for the last 6months. Only problem is that I seem to have lost a few of the batteries so I'm looking to make another purchase.
So I'm wondering if there are other/newer battery cells that exceed the performance of the Eneloop/Sanyo XX?
FWIW, I'm using these almost exclusively for wireless triggers and Speedlights, and I value a cell that is able to retain a high percentage of it's max capacity while not being used for weeks at a time.
