I rebuilt a battery and it didn't work. why?
hoping that rebuilding the battery pack would help, i bought 4 cordless phone batteries, each consisting of 3 smaller batteries and equaling 3.6v. all together that created the 14.4v that is needed to replace the original, acid leaked batteries. i wired them in series to get the 14.4v.
I think that it may have not worked because the original batteries were nimh (nickel metal-hydride), and these new ones were nicd (nickel cadmium).
Upon observing the internals of the laptop earlier, before i bought the batteries, i noticed some peculiar things:
-there were a few spots where some components were added, (eg- resistors, capacitors, jumper wires, all were smt)
-a unbranded piece in the battery power area, labeled on the board as XFER1. it is black and has five connections on each side of the component, which seem to have copper wires attached to them leading inside the component.
-no marked fuses on the board. the (apple released) manual for disassembling the machine states "you can blow a (soldered) fuse on the board", but there are no spots where a fx (x representing a number, eg: f1) is present, and most of the smt components in the suspected area are not marked and lok much like the same piece.
can anyone help me figure out what may be wrong? the ac adapter port works but the battery doesn't, would uploading pictures help people help me?
