The PB 540 I just got in from eBay came with two batteries that are both detected by the system and pass all tests in EMMpathy/Lind/Apple's utilities, so they are certainly good candidates to rebuild. While they do hold enough charge to keep the system in sleep mode unplugged, they will not power the laptop itself while it's on. When I do eventually get around to rebuilding them, I'd like to know a few things:
1. What cells should I use? I'd like to get like-for-like replacements to the original cells if possible, not hacking up a pre-built pack and fitting it in like some have done.
2. How do I get the casing open with the least damage?
3. Is there anything that I need to do, like keeping the EMM powered while I install the new cells?
Here’s a picture of the packs. No visible external corrosion!
