hi, I read thru it briefly, it looks like they have improved the self discharge curve with regards to remaining capacity of the battery. but its only 10% improvement after 30 days, a 20% improvement after 6 months and an infine improvement after 9 months because a standard nimh would be dead.
Any improvement is good of course, but nothing to get too excited about unless you dont use your batteries for a long long time after stopping all charging. I trickle my spares all the time on stanby, mine have essentially 100% capacity whenever I need them. These batteries would be of no help in my case, but your mileage may vary. >From what I have read, the best way to keep your spare nimh ready to go at any moment is to pulse charge them, that is you put a timer on a trickle charger and give them a low current "top off" charge for an hour a day. I have found by experimentation that a continuouse very low charge works too but it prolly degrades the overall life of the cells, I really dont know for sure, but its certainly nothing major because I seem to be getting same lifetime on my nimh batteries even with the trickling.

He's right and we are all wrong. He will assure you of that. I don't know why I even let myself get sucked into this sort of thread.
