It is "# With negative delta V cut-off function". While charging a battery's voltage steadily rises, untill it gets full then the voltage dips slightly, which the charger senses and turns off.
Charge them all when you get them. If you don't get around to using some of them within like, 6 months, charge them again so they don't self drain too much.
Actualy its a new thing, some of the newer batteries don't behave quite the same so sometimes the peak voltage detection doesn't always trip it off soon enough. others just use it as a failsafe, in case somethign screws up and the battery dangerously overheats. I wouldn't worry about batteries...
Its a whole 2 buck less now!
Man I remember when you got extra for trading in games with the box and manual and paid a little more for a used game with the same. Now its pay more no matter what. I'd be all over used games if it wasn't such a joke.
If its a smart charger it is okay. A 2 hour charge is only 0.5C, plenty slow if it stops charging at the right moment. If its a timer or one where you just leave it plugged in for however long, then yeah thats bad.
Its best to use a 'smart' charger. ni-cd batteries are very tough and can take quite a bit of abuse, but ni-mh are rather fragile in comparison. Overcharging (or overdischarging) them can ruin them quickly. Pretty much anything other than a flashlight will cut off before it overdischarges though.
I'm definitly keeping my cube untill i get wii component cables. I will probably end up up not doing anything with it and just keep it. I am such a packrat. I still feel sad whenever I think about how I traded in my SNES and a big pile of games for a PS1 and one game when I was younger :(
Yeah with Zelda I was playing laying on the couch with my hands stretched out over my head, relaxing from all the wiis ports I played with my friend and his little cousin early yesterday. That kid was hilarous, my friend filmed him on his digital camera, hopefully i'll be able to put it up on...
