OB600NiMHBattDissect.PDFOB600BattDissect Page 1 of 4 Omnibook 600 Battery Dissection I have a spare OB NiMh pack that's pretty well shot, so thought I'd look into the possibility of rebuilding it with new cells. It's the HPF1058A, rated 9.6 v and 1.7AH. All information presented here is for education only. I don't recommend anyone tampering with their battery packs, and take no responsibility whatsoever for any consequences of use of this information. Feel free to copy, share, or disseminate this info as desired, as long as this disclaimer is included. Some of the details here are similar to those that can be found in the article on rebuilding the OB300-530 battery pack on Chris Erickson's site. (or Alternative link) Although I haven't gotten to the point of actually replacing the cells, it appears that their size and shape is such that they could be replaced by the same cells mentioned in that article: Part # P016T-ND from www.digikey.com. Currently they are $4.93 each for the "T" part, with the metal tab
readme.txt4/26/2000 By Christopher Erickson 11/27/2000 Updated Rebuilding Omnibook 600C, 600CT and 800CT LiIon battery packs. Because of the difficulty in finding replacement LiIon cells, rebuilding these battery packs is not presently possible. It is speculated that LiIon cells are not generally available to the public because they pose a fire hazard if improperly handled. This includes shorting cells, excessive heat from soldering and other dangers. NiMH and NiCd cells have different charge and discharge characteristics than LiIon and it is assumed that the battery management circuit inside the battery pack is fully incompatible with all but LiIon cells. One last note is that LiIon cells are about 3.7 volts each, not like Alkaline, NiCd and NiMH cells, which vary from 1.2 to 1.5 volts each. This means that it would take twelve NiMH cells to replace four LiIon cells. If someone were to find LiIon cells for sale somewhere, I would recommend ones with solder tabs.
