SANYO 2700 AA w/lower self-discharge rate?

[chrome-addict]

I just noticed that the new Sanyo 2700 AA boasts "super lattice alloy technology" and lower a self-discharge rate. Does anyone know how the discharge rate compares to the Enloop AA's?

Their self discharge rate is still much higher than the eneloops.

IMO- Eneloop batteries are one of the best batteries you can buy right now. Very low discharge rate and enough power to power some high drain items plus you get alot more cycles with the eneloop batteries than you do with the higher capacity batteries.

I bought both. Plan to use 2700's when I need a lot of power like flash or heavy digcam use and willing to topoff at each use. Otherwise, I an using Eneloop for all other applications.

I did a test at 6 weeks, the 2700's still has much more charge over Eneloops with at least 300/400mah per C9000. Both batteries were new. Pleasantly surprised. Now running a longer test and will test later as batteries age.

This may be true for new batteries, but it is my understanding that to get the super high capacities like 2700 the separator is very thin causing the battery to be far less robust. A simple drop of these batteries off a desk is enough to tear the separator and send them into a whirlwind of self discharge. I had some Duracell 2650s that were working fantastic until I dropped my 360 controller, one of the two batteries quickly developed high self discharge after that event. I bought a ton of the Hybrids with the coups that were floating around, and I'll take the lower capacity of these batteries if they are more robust. So far they seem to be. I tossed a pack of them around for a while, knocking them around. I'm waiting to see how they deal with a little bit of physical abuse.

In defence of some of the higher capacity batteries, I have a pair of Rayovac 2500's that I have in a MiniMag at work that gets knocked around a bit and they seem to be holding up quite well with no indication of extreme self discharge.
