Having those as rechargable is very good! I just have some ordinary batteries as rechargable but those run out quickly. The Titanium ones I have aren't rechargable though. I wish they were.
Okay, I now have a DVD-ROM drive, a new CD-RW drive to replace my slow 8x (new is 40x), a CD-ROM drive, and two zip drives (I never even use the one ). I had to use one of those splitter cables to even get power to everything, LOL
