Interesting project. http://www.linuxjournal.com/content/rebuilding-laptop-battery Watch out for the (non)resettable fuse (depending on design) on some PCBs that blow to protect the battery pack from trouble: http://hackaday.io/page/247-replacing-lenovo-laptop-lithium-batteries http://hackaday.com/2011/08/01/who-knew-thinkpad-batteries-require-a-jump-start/ Then you also have to hope the rest of the circuitry is stll ok! These days I just hunt Amazon, or Batteries+ (local PDX-Vancouver, also can special order), for a good deal. The house repair "honey-do" list is never ending... _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
