Hi Rick,
Good questions. The Hybrio cells are similar to the other NiMH brand cells that are advertising the Ultra Low Self Discharge (ULSD) or "ready to use" aspects of these "new" cells. Are they really that new or just optimized to have way less of a self discharge issue? Hard to say since they have not been on the market all that long - at least in this country. That said, the Sanyo Eneloop, the RayOVac Hybrid, the UltraLast/UniRoss Hybrio cells are all much better at retaining their charge than the current highest capacity NiMH batteries in the 2700 mAh range. Which are really new and which are the same but with another companies shrink wrap on them? Who knows for certain... We are getting some ULSD cells with our greenbatteries.com brand on them really soon too. We are not going to advertise 90% charge retention though. I have obtained test samples of the Sanyo and Hybrio cells and they both seem to be over advertising the actual charge retention feature. I'll write more on that later, but for now these cells really do retain their charge for much longer. For the casual NiMH battery user this is a good alternative. Serious battery power hounds will still want to get the most mAh from their batteries, if they use the charged cell all at once and/or in a few days.
Remember, if you compared the 1800 mAh battery of yesteryear and a 2700mAh battery from the same manufacturer, but made today, you will typically get a higher self discharge rate in the newer higher capacity battery. Lots of variables though, it is hard to really nail it down unless you do lots of battery testing and analysis. I believe that the manufacturers do not really want it to be common knowledge to the general consumer that there is no best battery for all situations and that they have always traded one battery feature/attribute for another. i.e.- less self discharge usually results in less mAh capacity.
FYI - Battery manufacturers are certainly not going to divulge the specifics of their, sometimes proprietary, chemistries. This is kind of a good thing. We really want the battery makers to make better batteries for our future. Can you say lithium ion batteries for our cars... Now that is what I am talking about!!
Hope that helps.
Sincerely,
Curtis

I've been doing some research on these batteries on the web. The manufacturer of these is doing a real smoke and mirrors act on their website when it comes to the chemistry.
On your website they're billed as Nickel Metal Hydride. Is there anything more to the chemistry than that? When visiting the manufacturer's website, they make these cells sound like they have the low self-discharge characteristics of LiIon and the chargability of NiMH.
What's the scopp on Hybrio cells compared to conventional NiMH cells?
Thanks for your time. Nice website, by the way.
