Hi, i refurbished a Powerbook 540c pack with modern cells. They should probably have the doubble energy then the original ones. But there is something more. The electronic of the battery seems to calculate with the resistance of the cells. They are all soldered serial and there is already a resistor. Due to this all, the Powerbook 540c doesnt recognize the real capacity of the battery. Until now i didnt find the time, but next will be to measure the resistant of an original battery and then modify the self-refurbished with an resistor. So that the refurbished one has the same reading as the original. Probably then i get more power out of it. -- +---------------------------------------------------------------+ | () Gruesse/regards [EMAIL PROTECTED] | | /\ Manfred Guentner www.serv.de.eu.org | +---------------------------------------------------------------+ -- PowerBooks is sponsored by <http://lowendmac.com/> and...
