RE: z50 battery oddity

For what it's worth, I've tried www.batteryrefill.com for my old Thinkpad 570.

I am in Québec City, so if I throw the battery in a padded envelope, it'll get to you in a day or two. I'll send you another e-mail from my IBMCA address, and you can reply to that with a mailing address. You can buy me a coffee the next time I'm in mtl to cover postage :P

I am curious though, because in my experience, old laptop batteries that don't hold a charge still get up to their rated voltage with the mains plugged in -- they just don't hold it for very long once you remove the power.
