News New battery tech promises 20-second charge

I have even better news then this. A new charger that can recharge ordinary alkaline batteries up to 30 times. Yes those Duracell not-rechargeable' batteries!

 

It's sales hype juggling apples and pears

You can bet "an entire day" isn't 24, or even 8 hours. But lets think of the charger needed;

 

Doesn't a standard L-ion Battery have quite a high internal resistance thus the reason it gets hot when charged?
Wouldn't this make these batteries get really hot if charged quickly?
Or is the reduction of the internal resistance what's enabled the faster recharge times possible?

Anyway, supercapacitors should beat these in almost every way if what I've read/heard about them is to be believed.
In fact, I think there's been a screwdriver released in te states that uses supercap tech.
90 second chage for 90 mins of use.

 

ere stick ya tongue on this Xp, is it still charged? lol
