as a side note, i may have thrown out batteries in the past that i believed to be dead, but in reality, more than one of my controllers simply stopped working with the play n charge cable. i think i have two controllers now (out of 6) that will successfully charge a battery for more than 5 seconds.[/QUOTE]
Yeah, I had similar experiences with charge and play cable but when I got the quick charge kit, and the batteries started to actually last for 8-10 hours instead of 30 minutes. I had thought it was the batteries but after trading in a 2nd three month old "dud" battery to gamestop, I thought I should give the quick charge kit a try and it works much, much better than the cable.
