The charger is model MC-SC1400 and it is self-powered (doesn't use a power adapter). The battery charges great, but I don't know how long it will last in a computer, esp. one with a G3 upgrade. It was my spare, way back when, and it worked great when I stored it. I think it had about 45 minutes or so with my NuPower G3 upgrade, 233, less time with my NuPower 216.
Best reasonable offer as of about 7/1 can have both. It will cost about $5 to ship, and I will only ship to continental US.
Email me if interested.
