I need a battery pinout for this system.

Since I have largely given up on my A1181 (Late 2006) since the charge issue looks to be extensive and it needs other parts replaced, I don’t want to spend money if I can avoid it. I know this may not work so I’m setting my expectations low (expect it to not work, but hope it does).

Since the notebook can’t charge the battery and it shows every possible sign of probable motherboard damage, I’m seeing how I can jump the battery the notebook came with to try and see if the signs are board related. This is how the notebook behaves:

• Charge light comes on briefly but goes to green within seconds
• There are times the battery doesn’t show up when I tried to make it try by running without and replacing it. I need to cut power off before it even attempts to register it.
• The battery gets mV of charge if I constantly mess with the adapter, so it’s trying but either the computer is forcing it to stop when it does it’s sanity check or the motherboard has issues keeping it going. I also see it does hold a few mV of charge with a multimeter.

Since I do not know if the notebook even works (or if the motherboard is bad), I would rather not buy a battery and see if my existing unit is jumpable to get it to a state it’s going to even work at all. I’m going to keep what I put in minimal for safety reasons unless I somehow need more (3.7V max to start). I’m going to keep the notebook if it works (even though I’ve moved onto something newer, since I don’t want to waste this one) but if it doesn’t I’ll relegate it to a throwaway loaner with the caution it can’t charge batteries until it gets worse. I’m suspecting charge rejection because modern BMS boards (even copy onses) have onboard lockouts that create this problem. This protects the user, but requires these to be jumped to use them once it happens.

I cannot find a pinout for this battery I can work with, so I’m hoping someone here has one I can use to at least jump it and see if it’s the battery or motherboard.
