[Power] replacement RTC batteries for XO-1 and XO-1.5; which are recommended?

[Nicholas]

Sorry but this might be worse than useless info.

OLPC 1.5 and later RTC batteries appear to be CR2032 cells w/welded tabs and heatshrunk with a connector.

1: Salvage the old connector
2: Order some generic parts
3: Sit down and a skilled soldering iron wielder can spend an afternoon doing a dozen or so batteries laptops at a time (spend less than a half a second on each tab, waiting for the first tab to cool before going on to the second).

Helpful--or not :)
