Hello,
Started playing with my old Powerbook 1400c...and of course my battery is completely dead.
I was thinking about trying to rebuild/refurbish my old battery myself...by opening the battery case, and replacing the cells inside.
So far I have opened the case, and removed the intact battery pack.
The info on the battery pack is:
- Manufacturer Sanyo
- Model 8HR-4/3AU
- 9.6V
- 3500 mAh
- AL H
- Ni-MH batteries
I have read a bunch of "generic" articles on rebuilding/replacing the batteries in the a laptop battery pack...my problem is, when it comes to my specific Powerbook 1400 battery, I cannot find replacement batteries for the battery pack.
Many of these "generic" articles say find some 1.2 volt Ni-MH AA batteries (preferably with the metal tabs on the ends of the batteries).
The problem is, the Powerbook 1400 battery pack has 4 long cylindrical batteries comprising the battery pack...and each long cylindrical battery is longer than 2 AA batteries (see picture).
So if I used 8 AA Ni-MH 1.2v batteries...they wouldn't be long enough to fill the original plastic battery case.
So my questions:
1. Has anyone successfully done this (replace the batteries in a 1400 PB)?
2. Anybody know where I can get the proper length replacement batteries for the battery pack?
Thanks,
- Nick
