Anyone else seen this system? Rayovac has put out a battery/charger combo
that includes a charger that will "safely" charge four 2000mah AA or AAA
cells in 15 minutes for up to 1000 charges! I don't know if you have to use
their cells only but it is intriguing to say the least. I have been building
my own packs for years so this has definately piqued my interest!

and for just over $40 US! (including four 2000mah AA cells)

Well it's quite obvious that marketing wonks have take over the Ray-O-Vac
company.  Kind of like these come on adds where you can win up to $10,000.

Just what do they really mean when the say "up to"?

And for the record, this Rayovac I-C3 Technology 15-minute Charger
is not the "the first of its kind".  General Electric sold a 15 minute
system and held the patent on 15 minute charging over 30 years ago.

Check your US Patent Office for Pattens by F. H. Mullersman (General
Electric) around  1971 to 1973 time period.

Upon further reading on their site, I noticed that they claim the batteries
"monitor their own internal pressure" and that it is not the charger but the
battery technology that permits this high rate of charge. Do you know how
this is acheived?
