WTB: 2nd battery for Dell laptop...

[SaberX]

I know this is mostly a Thinkpad place but seems like a nice few people here still use Dell Laptops.Thought i would try here befor e-bay.

Looking for a 2nd battery that goes in where the dvd-rw drive is.
The model # that i found is Type: 4R084
Rating: 11.1V=== 4320mAh

And will fit the Inspiron 500m, 600m; Latitude D500's, D505's, D600's, D800's; Precision M20, M60.
I'l looking for one for my D820.

Thanks
Bill
