Re: How many battery "breakthroughs" is that this year?
It's almost as if we've erased from our collective consciousness the horror that was NiCad.
Oh, to be young and naive again!
Once upon a time (up until the nineteen seventies), the portable world ran on carbon/zinc drycells.
Anything under D size was practically worthless, and it took a minimum of two of those to give you nearly a half hours use.
Then you chucked them, bought more, and carried on for almost another half hour, provided they hadn't leaked and eaten away the electrical bits of the device.
Compared to them, NiCads were a godsend!
But, everyone knows that batteries have never improved, so I'm told. ☺
