I'm using the Maha 801D. Great charger/ individual circuits for each battery, soft and normal charge modes plus soft an normal recondition modes. 8 cells AA or AAA any combo.
using 16 Eneloops now, but with four flashguns I'm gonna need more! Panasonic may change things I don't know but I found that when I read the data sheets CLOSELY I found that the eneloops optimize the things important to me (charge cycles and flash recycle time). there is no free lunch, so of the four parameters:
charge cycles (life)
capacity (number of flashes per charge)
internal resistance (recycle time)
self discharge rate
you can't optimize all four at the same time. increase capacity and you will give up internal resistance and/or number of cycles and discharge rate. Batteries with the highest charge cycles rating will tend to have a lower capacity
