You can buy external laptop batteries from www.batteryspace.com. They have NiMH packs with multiple plugs to adapt to various laptop power jacks. I'm not too sure how long their warranty is, but I've never had problems with their batteries.
Just out of curiosity, why do you want an external battery?
Try http://www.ebuybatteries.com , they have many IBM laptop batteries, not sure internal or external, but they have 1 year replacement warranty. Good service, quick email response.
