They are however most likely to have a short lifespan....
Not any known fact just my experienced opinion... :D

Re: NEC produces 30 second battery charge
 

the battery lasts 80 hours in a minidisc player, zoombini........

Re: NEC produces 30 second battery charge
 

mmmmm... must be some charger!

By my calcs:

charge_current >= 80 * 60 * 2 * discharge_current

If the minidisk player takes a mere 100mA then the charge current must be greater than 960 amps - that's gonna get hot!

lol talk about a bunch of whining people, lets not slag this technology down before seeing it in action ?

seems promising if it lives up to its specs......

Re: NEC produces 30 second battery charge
 

Sounds ideal for my digital camera

Cyclon lead-acid cells have been around for years and support 'practically unlimited' charge currents:

i dont think its the same technology........

:shrug:

Re: NEC produces 30 second battery charge
 

That's not the lifespan, though. It may well last 80 hours in a minidisk player, but it doesn't state how many times it can be charged before it can no longer accept a charge and will need to be replaced.

Cylon batteries provide a charge that can last thousans of years :D

Re: NEC produces 30 second battery charge
 

the lifespan stated was the longest time it would last, charged, as with all battries such as rechargeables you do need to replace them eventually.......

Re: NEC produces 30 second battery charge
 

There would be a huge demand for batteries like this. Kids toys would would be given a boost. I would love to have my remote control car last longer than 20 mins. Along with my camera, my mouse, cordless headphones, mobile phone.

maybe they will be swept under the rug though a la "the prisoner"... it would put duracell etc etc out of business wouldnt it, and of course we cant have that...:pp

Re: NEC produces 30 second battery charge
 

I reckon the drawback will be cost.

Incog.

Re: NEC produces 30 second battery charge
 

Kronas mate, I don't think that your following what I was saying.

The charge time of the battery may be 80 hours, but at a very high charge rate it is very common for the lifespan (how long it can be used before its nackered - not gets flat) to be considerably shortened by it.

ALthough we can only hope that it will be a superb battery, last ages & do what its supposed to do for a long, long time..
All hail battery development.. :D
