I did read that it would charge 150 times, which they equated to a year's of use. I do not use batteries like they seem to be speaking of, as in portable PCs, etc. but it would be nice if the technology was extended to regular AAA, AA, C & D cell batteries. Yet, it may be too expensive, even if they did, because I get a lot more charges than that on the batteries that I use. I have some Ray-O-Vac AA 15 minute rechargeables that are over 7 years old, and are still working.
